Buck PomerantzI've been tinkering with electronics ever since I was a kid - starting with taking apart and putting back together televisions and radios. I always got them back together again and working. I took courses in radio and electronics as a teenager, and became a ham radio operator. I worked in my high school's stage crew, running sound, lights, and a movie projector. After college, I joined a rock 'n roll band as the soundman and learned how to lug around and operate the gear that helps make music sound good and loud.Working in a music store in Austin, Texas, I spent a few years manufacturing, installing, repairing, and operating sound systems. Our customers were recording studios, nightclubs, and touring bands. Eventually I moved back to Charlottesville, Virginia and opened a small demo recording studio.
In 2006, I finally came to my senses and got this job at Crutchfield. They actually pay me to ramble on, rant, and explain the things I love about music, electronics, and getting good sound.Given my background, they put me to work writing about some of the most complex electronic products Crutchfield sells: car amplifiers, digital signal processors, wiring, professional sound mixers, and PA systems. Ported enclosure with dual 10' CompC subwoofersConfusion concerning watts, amps, and ohms has been around for as long as people have been putting subwoofers in cars. Watts and ohms are entangled in a series of mathematical formulas that link them intimately together such that when one of them undergoes a change in value, the other often does too.
Briefly, here's how it worksAmplifiers provide the electrical pressure in a circuit; ohms measure the resistance, or load, against that pressure; and watts measure how much power is released as work. So, using one of those math formulas, an amplifier that provides 100 watts of power through a 4-ohm speaker, will produce 200 watts through a 2-ohm speaker, because it's easier to push that reduced load. Voice coil makes sound — amplifier pushes itAt the heart of every speaker and sub is a voice coil. This is the device that puts up the electrical resistance and performs the work.
(The amplifier provides the power.) The resisting property of a coil is called its impedance and is measured in ohms. The lower a speaker's impedance, the easier it is for an amp to supply power to it. Problems arise when the amp's output meets very little resistance (low impedance) and it tries to put out more power than it was designed to produce. This leads to the amplifier overheating and then, hopefully, shutting down to protect itself from burning up.
You don't want the amp to over-do itSo the capability of an amplifier has to be considered before applying a load to it (hooking up a speaker). The manufacturer's specifications indicate an amp's minimum impedance requirements.
Almost all amps can drive a 4-ohm load. Most amps can work with 2-ohm loads on each channel, but not when the channels are together. Some amps can drive a load as low as one ohm. The two channels of this can be bridged by wiring the sub as indicated (click to enlarge) Wiring options change a sub's impedanceTo add to the confusion, in multiple-sub systems, the total impedance depends on how the subs and their voice coils are wired together — in parallel or in series.
Parallel wiring means that the connection ends of each device are connected to the same things — plus to plus, and minus to minus. Series wiring means that the devices are wired one after the other — a plus of one to a minus of another.When speakers or voice coils are wired in series, you add their impedances together to find their total impedance. Two 4-ohm speakers wired in series have a total impedance of 8 ohms. When speakers or coils are wired in parallel, however, the formula for their total impedance is more complicated.
When the impedances of all the devices are the same, their total impedance, when wired in parallel, is that impedance value divided by the number of devices. For example: four 4-ohm speakers wired in parallel have a total impedance of 1 ohm. This has a built-in jumper so you can choose whether it has a 1-ohm or a 4-ohm total impedance (click to enlarge) Dual Voice Coils give you even more wiring optionsSubwoofer manufacturers make subs with dual voice coils (DVC) to take advantage of this difference in wiring schemes, so the user has more freedom of system design. A DVC 4-ohm sub can be wired into a system as a or as an load. A DVC 2-ohm sub can have a total impedance of.
An example using 4 subs:If I wanted 4 subs in a system, I might consider using 4 DVC 2-ohm subs, each with their voice coils wired in parallel to make them each 1 ohm subs, and then wire the 4 of them in series so my amplifier could drive them as a single. Or, I could wire the voice coils in series, making them all 4-ohm subs, and then wire the subs in parallel so the amp would see the total load as. It would depend on my particular amplifier — which load it would do the best with. Match power to power — use RMS onlyTo make subwoofers sound their best, they should be powered by an amp whose RMS output rating comes close to or even slightly exceeds the total of all the subs' top RMS ratings. If you want to run three subs whose RMS ratings are 300 watts each, you'll need about 900 watts RMS of power to run them.Underpowered subs won't sound good or play very loud.
Then, if you were to turn up the input to compensate, the amp could end up sending out clipped or distorted signals that could damage the subs. It's okay to overpower your subs a little bit, as long as the signal's distortion-free, because they're made to withstand occasional peaks well beyond their normal RMS rating. What's right for you?The sub and amp you need depends on what you want to hear. If you plan on listening to music at moderate volume levels or have a smaller car, a subwoofer with a lower power handling rating, say 100 to 250 watts, and a matching amp is a good combo.The ultimate goal is to have the amp send its full power to subs that can handle it. The object of using different wiring options to optimize the impedance is to get the most power out of the particular amp and subs you have at hand.
This also happens to be the most efficient way of running an amp & sub system. For more wiring specifics, check out our.If you want to get right into choosing a subwoofer, take a look at.
Ryan Blythe from Mooresville Posted on 3/25/2019I have a 2010 Chevy avalanche that I want to add new door speakers and a sub to. Would I be better off with a 5 channel amp and running at 4 ohm or doing a separate mono and dropping impedance. I am not sure what side of the coin to shoot for. I don't want crazy competition bass but I would like a little power. Also in that truck should I do a single sub like a 10 or 12?
Will the 5th channel run a pair? And at what rms should I run new door speaker wires? Thanks for your help. Anthony Simmons from Omaha Posted on 3/7/2019I have 2 old but never used kicker comp s 12's svc 4 Ohm about 600 watts 300 rms apiece and, a lanzar 3000watt 1500rms 2 ohm amp. I though that I should wire them down to a 2ohm load but after doing some research.
To protect the amp and the speakers I've read that I should wire them in series so the amp which (after researching it) tends to get hot when wired for max power (I dont need that much power anyway) I read that wiring them in series will save the life of my subs and amp. It's a budget set up so I'm trying to be careful. I know alot of what goes on with a sound system depends on specs and wiring can you tell me if im headed in the right direction for the equipment that I have?
Peter Posted on I really do not know where you chaps are getting your ideas from! The solution to all of these matching problems is clearly explained in the Maximum Power Transfer Theorem which states quite unequivocally that Maximum Power is transferred when the impedance of the load matches the impedamce of the source. If there is a mismatch in the impedances either up or down the transfer of power will be less.
The amount of power is irrelavent provided both source and load are capable of handling It. All power references should be in RMS for accuracy. The answer then is simple, make sure you know the impedance of the source then match the impedance of the load to it as near as you can, or if you already have the load then match the source to it.
One thing to remember- the high currents you are talking in, 400W at 2ohms is 200A and will need really hefty cables to conduct it and the impedance of these may need to be worked into your equation. Matt from Los Angeles Posted on 6/21/2018Hi Buck, I'm trying to figure out the best impedance load for my Tesla 3, which has a 250 amp fuse feeding the 12 v system. So that's a limiting factor. I have several amps and an AudioControl DM-810 DSP for a full SQ build, but my main question is about the sub configuration. The sub amp is a Rockford T2500-bdcp, which will run a 10 in Sundown NSv4 (2,500 w RMS). I want to prioritize sound quality rather than just sound pressure, while keeping in mind that I only have a 250 amp main fuse.
Amps get less efficient at lower impedance loads, but will running the sub at 2 vs 4 ohms be much of a difference for the low end sub? It's a DVC that I can order in either dual 1 ohm or dual 2 ohm for either 2 or 4 ohm wiring. Note that the sub will have two 10in passive radiators, and I'll probably cross it over at about 65hz. I also have two 8 in woofers on 200w each that will pick up from about 55hz to about 125hz.
For the main sub amp (T2500-bdcp), it will RMS 3,100 at 1 ohm, about 2,600 at 2 ohm, and about 2,000 at 4 ohm. I'd like to do 4 ohm, but I'm not sure that's enough power for such a beefy sub.
Thanks in advance. Jay from NPB Posted on 4/18/2018Hello Mr. Pomerantz, I have (2) DVC 2 Ohm Pioneer shallow mount subs being powered off of a 1000w Sound stream class D mono amp with only one +,- out put. The amp can handle either 4 or 2 Ohm loads. I want to run the subs at 2 Ohms so I wired the DVC in series on ea. By adding a small jumper wire connecting the +. Of them and paralleled + to + to the + terminal and did the same but for the - side.
I just want to know if the amp will see that as a 2 Ohm load, or a 8.? Thanks, Jay.
Jaecen Foytik Posted on 4/2/2018Hi, I've got a Planet Audio AC12D 4-ohm DVC 12 inch subwoofer and a Crunch PZX1800.2 class Ab 2-channel amplifier.The amp is rated for 900w rms bridged at 4 ohms and 450w rms x 2 channels at 2 ohms. Is there a way to wire these 2 in order to achieve the full 900w rms? I'd rather not go to 8 ohms, but will wiring at 8 ohms cut the output in half? What about wiring in bridged mode and adding a 2 ohm resistor to make it the 4 ohm impedance? If it's not possible to achieve the full RMS, would this mean I need to change the sub or amp? Thank you in advance!. Dillon from Sierra vista Posted on 3/20/2018Im building a system and was wondering.
Do i have to bridge my Sub? Here is what im looking at:Rockford Fosgate R169X3 Prime 6 x 9 Inch 3-Way Full-Range Coaxial Speaker x2 (130w total RMS)Rockford Fosgate R165X3 Prime 6.5-Inch Full-Range 3-Way Coaxial Speaker x2 (90w total RMS)Pioneer TSW261S4 10-Inch Champion/SINGL 4OHM/1200W/4 Equalizer (350w RMS)and the amp I'm looking at isCar Amplifers BOSS Audio PV3700 Phantom 3700 Watt, 2/4 Ohm Stable Class A/B, 5 Channel, Full Range, Bridgeable, Mosfet with Remote Subwoofer Control (but I've read that RMS is close to 1000w)Is this amp to much and if so could you reccomend one to fit my build that's under $120.
I would like to connect all 4 speakers and the sub to it.Thanks in advance. Jay from NPB Posted on 2/20/2018Hi Buck, thank you for the FAST reply!
I understand - I ended up using a on-line speaker Ohm calculator and got 1.7 Ohms with my new speaker configuration. I decided to use a mono block amp for the 8' speakers. The mono block is fully compatible with my other amp.
![]()
This now leaves me a 2 speakers wired in parallel configuration, a tweeter at 3 Ohms and a mid at 4 Ohms on one channel of the 4 channel amp. My question to you is with music/frequency variances will my 4 channel 2 Ohm stable amp see this 1.7 Ohm load as a 2 Ohm load and clear this minus.3 Ohm hurdle.?. Buck Pomerantz from Crutchfield Posted on 2/19/2018Jay, First of all, measuring a voice coil's electrical resistance to DC is not the same as measuring its impedance to AC. Secondly, that is not the way to figure the total impedance of three speakers connected together. For example, three 4-ohm speakers wired together in parallel will have a total impedance of 1.3 ohms.
It sounds to me you should give us a call and talk to an Advisor about what will accomplish your goals. With questions like this, it's always better to have a conversation with a real live human in order to get what will work best for you.
Jay from NPB Posted on 2/18/2018Hi Buck, I am in the process of replacing the speakers in my '04 Tundra D.C. It has the JBL H.U. I cant find ANY useful or reliable info on this system as far as H.U. Or amp specs.
I have taken measurements with my digital multi meter and thought I would simply replace the existing speakers, keeping the Ohm the same as original, in hopes of the original amp powering them - I mean why wouldn't it - the 14 yr. Old newer speakers should be more efficient, so I thought. Now that the speakers are in and I turn up the volume I can tell that it's not as loud and their is some distortion/clipping occurring. So now I have decided to replace the WHOLE system! As it stands all the speakers which I installed and look great are Infinity 6.5' 2 Ohm Kappas 75 RMS/225 Peak in the rear doors, Pioneer 8' 2 Ohm DVC 150 RMS/300w Peak (wired in series for 4 Ohms -.the front doors were 2 Ohms originally but sound better now wired 4 Ohm) in each front door, Massive 2' 4 Ohm 20w RMS/40 Peak mids.
At the 2 0'clock position of the 8' subs, and Infinity 3 Ohm.75' tweeter 45 RMS 135 Peak in the door sail panels. I am planning on installing a Pioneer AVH-200-EX this week and a Soundstream ST4.1200D amp., I am trying to figure out how I can satisfy all loads and thought I would combine the 8' + 2' +.75' (according to your above Ohm calcs. That would average out to 12 total Ohms divided by # of speakers = 3.66 Ohms. Can my amp handle this load.?
Will the new H.U. Add power to the amp?. Buck Pomerantz from Crutchfield Posted on 10/3/2017Jason, Your mono, 1-channel amp has 2 sets of speaker output terminals, wired together inside the amp, for convenience, and if you hook a speaker to each terminal it would result in the two speakers being wired in parallel, cutting the total impedance in half. JL Audio makes 2 versions of their 12W3v2 subwoofer - a DVC 2-ohm (12W3v2-D2) and a DVC 4-ohm (12W3v2-D4).
If you have the 2-ohm subs, you wire them to that amp. If you have the 4-ohm models,. In both setups, each sub's voice coils are wired together in series, while the two subs themselves are wired together in parallel. Matt from Los Angeles Posted on 8/3/2017Hi Buck: I appreciate your prompt response and apologize if I buried my in all of the specifics.
What I meant to ask was a little more technical than whether it's possible to replace factory subs: Will I significantly endanger my factory amp if I install a 1ohm speaker to replace a factory 1.25ohm speaker? That is a 0.25ohm drop, which doesn't seem like much, but I want to get your opinion because your responses show that you have a lot of experience with this kind of thing. I wish I could tell you more about the factory Bose amp, but as I'm sure you know, neither Bose nor Mazda publishes technical specs on it other than a wiring diagram that says the factory door subs run at 1.25 ohms. I've also read online people testing with a power meter to confirm around 50 watts to each door sub.
Other than that, all I know is that it stays clean and has decent power. Thanks in advance!. Matt from Los Angeles Posted on 8/3/2017Hi Buck: My question is whether it's safe to replace a shallow factory subwoofer running on 50 watts each at 1.25 ohms, with an upgrade to shallow subwoofer rated at 150 RMS (600 max) and 1 ohm? If not, would my loss in volume (db) be noticeable from installing an alternative replacement rated at 150 RMS (300 max) and 2 ohms?Specifically, I'm swapping out the stock 8' door sub-drivers (Bose KD45-66-A60) in my 2017 Mazda 3 Grand Touring Hatchback. One replacement option is a dual 2 ohm voicecoil (Infinity Ref-Flex8S) or a single 2 ohm voicecoil (Infinity Ref-Flex8D), but hopeful the dual wired in parallel for a 1 ohm load (first question above). The other option is a single 1.76 ohm voicecoil (Earthquake SWS-8xi).Thanks in advance!. Buck Pomerantz from Crutchfield Posted on 7/15/2017Avery, That 4-ohm 300 watts RMS rated sub may be overdriven by a 500-watts RMS amp, but then again I don't know exactly what your issues are.

Buck Pomerantz from Crutchfield Posted on 3/27/2017Hein, If you're referring to an SSL EV2.200 amplifier, I would advise you not to connect it to that sub at all.
That amplifier is a non-bridgeable 2-channel amp capable of putting out up to 75 watts per channel, which won't do much good for a 200 watts RMS rated sub. Mega evil clash of clans. You should look for a mono subwoofer amp capable of putting out between 150 and 300 watts RMS at 2 ohms.

Brandon from newnan Posted on 3/7/2017Hi Buck, I have a Kenwood 7252 2 channel amp wired to bridged mode with my shiny new JL 10w3v3-4 subwoofer. The owners manual for the Kenwood says in bridged I have 500 rms @ 4ohm, while the sub is 500 rms @ 4 ohms.
When I crank the sub to loud but still reasonable jamming volumes it seems the amp is working extremely hard. I have it wired up with a lightning audio 8 gauge wiring kit.
I also have a seperate amp and wiring kit to my door speakers, alpine pdfx4 which is working fine./Now i realize that my Kenwood amp is about ten years old could it be time to replace with a mono amp? I guess i should have gotten that sub in a 2-ohm version as the cost per watts is cheaper @ 2 ohms vs 4.Please help thanks. Buck Pomerantz from Crutchfield Posted on 3/1/2017Zach, If you were to wire your subs to that amp in the manner you describe, the amp will see a total impedance of one-half ohm and go into protection mode or burn up. Your mono, 1-channel amp has 2 sets of speaker output terminals, wired together inside the amp, for convenience, and if you hook a speaker to each terminal it would result in the two speakers being wired in parallel, cutting the total impedance in half. Two DVC 2-ohm subwoofers can only get wired together to form a one-half-ohm, an 8-ohm, or a. Buck Pomerantz from Crutchfield Posted on 1/4/2017Shannon, There is no best, there only is.
Parallel and series are different wiring schemes that get used in different situations - one isn't better than the other. Bridging refers to adjacent channels of an amplifier that can work together to produce more power than just one channel. It isn't better or worse than unbridged amp channels. An RCA connection is a line level connection.
Perhaps you were thinking of speaker-level connections, hence your reference to an LOC. Almost all car amplifiers made today feature built-in line level converters and will accept speaker-level inputs. The advantage of using one is convenience. The best way to choose components for a car audio system is to give Crutchfield a call (1-888-955-6000) and talk to one of our Advisors who'll make certain you get the right gear for yourself and your vehicle. Shannon from Gotham City Posted on 1/3/2017This question is certainly subjective for each listener and may vary depending on how many components and will have to be termed 'generally speaking'.Assuming all component ratings are equal to (or near to suggested specs) ex. Rated speaker/amp ohms, wattage, etc. Using mfg suggested wiring.
What do you think is the best (subjective) way to wire Parallel or Series or Bridged? What are the pros and cons of each?And then your thoughts, feelings, xp (pros and cons) on wiring RCA versus Line input? Is sound quality or bass response any different between the two (any advantage between LOC to just amp line inputs - where available)?Lastly does a factory HU vs aftermarket change any of your answers to the above?Maybe another way to put it is (in a perfect world, unlimited budget yeah right) how would you wire/install and choose components for your own personal system?Me personally, I want quality sound, tight bass (decent thump but not a rattling, deafening bass, yes I am aware of dynamat). Buck Pomerantz from Crutchfield Posted on Josh, I can find no information about a JL Audio w-1X3 subwoofer. If you meant their W1-v3 model, then you could wire two of them to that amplifier.
Make sure the amp gain is set so no distortion can play. Your mono, 1-channel amp has 2 sets of speaker output terminals, wired together inside the amp, for convenience, and if you hook a speaker to each terminal it would result in the two speakers being wired in parallel, cutting the total impedance in half. For your set-up, that's exactly what you can do: wire one sub to each set of terminals.
It's electrically the same as in the diagram. Kevin jefferies from Virginia Beach Posted on i have 2 svc kicker subwoofers 4 ohms each, 300 rms each running a 4 channel 1200 watt amp, i know 4 channel isn't meant for 2 subwoofers but I'm trying to work with what i have. My amp says '2 Ohm stable stereo operation' but i think that for speakers so i don't know if that has any thing to do with the subwoofers. The amp description says ' Power output: 150 Watts x 4 at 4 ohms; 300 Watts x 4 at 2 ohms; 600 Watts x 2 at 4 ohms bridged' I'm trying to get the most bass i can. How should i wire it. Lauro Gallardo from Phoenix Posted on 9/2/2016Mr.
Pomerantz.I recently bought a 10 ' Clarion SVC, rated at 300 rms, 4 ohm.I have a very basic amp, it is 2 channel, 50 watts x 2 at 4 ohm, and 100 watts x 2 at 2 ohm.I know I will underpower my amp, but not by much, my concern is with the Sub, only says 4 ohm, and I will bridge the amp to give the sub 200 watts at 2 ohm.Can I damage my sub, or my amp by doing that?Sorry if I sound confused, the true is that I really am, as Im just entering in the world of car audio. Buck Pomerantz from Crutchfield Posted on 7/27/2016Darren, That subwoofer comes pre-wired internally to present a 2-ohm load at its terminals and there's really only one way to wire it to an amplifier. Using dual-lead speaker wire, connect the positive and negative terminals of the sub to the positive and negative output terminals of the amp. The amp has two pairs of speaker output terminals that are wired together - just use one set. If your amp is a Pioneer GM-D9601, the recommended power and ground wiring size is 4-gauge. Bogdan from Bacau Posted on 4/19/2016Hi,I think i have a problem with heating of a JBL GTO 75.4 amplifier.
Daniel from jericho Posted on 3/30/2016I have an alpine swr-1241d DVC subwoofer with 2 4ohm coils, so it can either be 8 or 2 ohm. I also have a kenwood 7201 amp, which is 2ch 150w @4ohm, or bridged 460w @4ohms, it is not 2ohm stable bridged. This sub will be replacing the stock sub (though in its own ported enclosure) in a 2012 non-tech pkg Acura TL, the rest of the sound system will remain the same.
I will use a LOC with remote turn on off the stock sub wiring for signal.which would be better to power the sub, running each channel to a coil seperately, or running the coils in series at 8 ohms?It seems like running the amp in 2ch mode would give 300w, whereas running it bridged at 8ohms would only give 230w. The 8ohm wiring would NEVER tax the amp.
Would I notice a difference in quality between the two wirings? Would I notice a difference in volume progression (how much the sub signal is amplified compared to the rest of the system.
I.E will the sub get louder faster for the same signal on the lower resistance?). Buck Pomerantz from Crutchfield Posted on 3/21/2016Jeremy, The Rockford Fosgate P1 2X12 is an enclosure with two 12' subs and a total impedance of 2 ohms, so you couldn't have wired it as a 1-ohm load to that amp unless you connected two of them together.
Then, the amp would have gone into protection mode and saved your subs. It sounds like the amplifier's gain was never set correctly, which could have led you to play distorted signals trying to get enough bass sound, and burn out your sub. Check out for help setting an amp's gain.
Trevor from Winnipeg Posted on 3/21/2016Hi,I just bought an Alpine SWR-10D4 Subwoofer, (dual 4 ohm voice coils, rated 1000W RMS), off of a friend. When he had it he had a 1000 watt amp and ended up frying the sub after using it just 40 minutes. By the time he got it replaced under warranty, he decided to buy a different one anyway so sold me his replacement. I obviously don't want to break this one, and was wondering what amp/wiring combination you'd recommend? Goal is to put the least strain on my alternator/amp/sub. It's going in a ford fusion if that makes any difference.Thanks.

Michael Damian from College Station Posted on 2/20/2016I have 2 kicker comp r 12' subs and want to know if its possible to hook them up to a kicker dx 1000.1 mono channel amp? The subs have only one positive and one negative terminal per subwoofer. Each subwoofer also has a switch that you can flip to either 1ohm or 4ohm.I tried wiring a positive and negative terminal together between the two subs, and then wiring a positive terminal on the subwoofer to a positive terminal on the amp, and then wiring a negative terminal on the same subwoofer to a negative terminal on the amp. I also had the switches on both subwoofers flipped to 1ohm. When doing this, the subs would hit hard, but would cause the power protection light to come on and then cause the subwoofers to stop playing at that volume. This was my attempt at series wiring without understanding ohms, which is why I tested it out by setting both subs to 1ohm.I then tried wiring a positive terminal to a positive terminal on each sub; same with the negative terminals. I then connected the positive terminal from one sub to the positive terminal on the amplifier, and then a negative terminal on the same sub to the negative terminal on the amp.
When doing this, I had the subwoofer switches both flipped to 4ohms. This was my attempt at parallel wiring, but it failed.
The subwoofers don't hit as hard, and the power protection light still comes on when they hit hard.I could really use some help, would like these subwoofers to work well with this amp. Danny from Rochester Posted on 2/16/2016HiI recently purchased 2 kicker type r 12' dvc 2ohm subs. Only thing is they have an Independence switch on them for 1ohm or 4ohm. I also have a Boss ar4000d monoblock amp I would love to hook these subs up to this one amp. Some say it can be done no problem some say it can't be if I set the Independence switches to one ohm my amp is 1ohm - 4ohm stable how should I wire these subs to my amp without cooking anything? I've looked all over the internet for diagrams and I am totally stumped.
And I don't want to fry my subs or amp any help would be appreciated. Buck Pomerantz from Crutchfield Posted on 1/26/2016Andrew, Two SVC 4-ohm subwoofers get wired to an unbridged 2-channel amplifier, because 2-channel amps are rarely stable for 2-ohm loads when bridged.
They'd connect to a mono, 1-channel amp, where the two subs are wired together in parallel, halving the total impedance. Whichever way they're wired, each sub will receive one-half of whatever wattage the amp can put out. So if your amp has a total output of 550 watts RMS, each sub will receive 275.
Andrew M from Massapequa Posted on 1/25/2016I'm a little confused. If I have 2 SVC 4ohm subs rated 275w RMS each.and my wiring options are 1) to a 2ch amp 4ohms each channel, the amps rms should be close to 275w.2)but on a single channel (mono/bridged) in paralell seeing 2 ohms. Should the amp be rates 275W rms at 2ohms with both subs in parallel each seeing the same wattage, or do i need an amp capable of producing 550w on a single channel seeing a 2ohm load?
I think I typed all that out correct haha. Im confused about what amp rating I should look for when wiring in parallel, normal rated rms for one sub, or double it.
Jimmy mccarty from Dos Palos ca 93620 Posted on 1/21/2016Hey how's it going I have to earthquake 10 inch subwoofers they are 4 ohms and single coil I wired them down to 2 ohms to get more out of my amplifier because it is 2 ohm stable I did not really notice a difference though I think it could be my the battery or maybe I need to just do the big 3 upgrade my lights dim real bad too sometimes and I noticed my amplifier use to cut off on certain songs the amplifier would go into protect mode and that was 4 ohms now I have it at 2ohms. Buck Pomerantz from Crutchfield Posted on 12/7/2015Jag, I'm afraid you have the meanings of the terms 'series' and 'parallel' mixed up. When two inductors get wired in series (one after the other), you add the impedances; when parallel (positive to positive, negative to negative), you divide by two. Secondly, you're asking about two very different kinds of subwoofers which have very different requirements for amplification.
The Pioneer sub is DVC (dual voice coil) 4-ohm rated for 600 watts RMS operation. That JL Audio sub comes as a SVC (single voice coil) 2-ohm or SVC 4-ohm model rated for 300 watts RMS. If you're choosing the subs before an amp, you'll have to settle on exactly which model and how many (two?) before being able to spec out which amp will work. Should help.
Jag from Round Lake Beach Posted on 12/7/2015Hello, I'm trying to decide between Ts-w3003d4 and the JL W1V3 subs. I'll be installing these in my existing 12' system.
The subs are sitting coil up in my trunk in a custom moulding. No enclosure.
What would be the best amp to drive these? I am thinking of wiring the 2 coils in series to make them 1 ohm subs while attaching to the amp in parallel, making the amp see them as 2 ohms.
Can this work well? If my thinking is correct, I can get the max RMS power from my subs (as they will be running with 1 ohm resistance), while not trying to push the amp to handle 1 ohm but maybe an amp that can safely handle 2 ohms, 1000 RMS if i go with the pioneer and 600W RMS with the JL's (however, they are rated as 2 ohm 300W RMS subs). If my subs are rated as 2 ohm, can I safely connect them in series to make them 1 ohm?
Does this double my RMS power handling? OR would it be safer to connect them in series as 2 ohms each and in parallel to the amp so the amp sees 4 ohm?Thanks for all your help!. Buck Pomerantz from Crutchfield Posted on 12/4/2015Scott, The only way I can think of to safely connect your gear together is to open the sub box, disconnect the two subs from one another, and wire them to separate channels of the amp.

Buck Pomerantz from Crutchfield Posted on Alain, Not knowing exactly what your car audio dealership said nor exactly how your friend wired your system makes it hard to say what's going on. My guess would be they found the two amp channels bridged together and running that subwoofer wired at 2 ohms, and so rather than spend a lot of time and energy rewiring your system to operate safely but with no additional power possible, they deferred. The only way I can see to wire that gear together is to un-bridge the amp and run each of the sub's voice coils with an amp channel. That way, the amp could send the sub its RMS ratings - 200 watts per coil, 400 watts RMS total. Just make sure each channel of the amp gets the exact same input signal - use a Y-cord.
Buck Pomerantz from Crutchfield Posted on Roberto, Those two subwoofers can only get wired together to form a total impedance of ½ ohm, or 8 ohms. The amps you mention can both handle them wired as a 2-ohm load, but would probably overheat and shut down with the ½-ohm load. A 2-ohm load can be created by either wiring two 1-ohm subs in series, or two 4-ohm loads in parallel. If you aren't familiar with the difference between series and parallel wiring, just set those switches to 4 ohms and wire the subs like in the provided link.

Buck Pomerantz from Crutchfield Posted on 9/28/2015Yannick, Your second and third options will be louder than the first - 500 watts will play louder than 300. Nominally, the second and third options should play the same - the amp sees a 2-ohm load and tries to output 500 watts through it - but the two subs may have different sensitivities.
That's a specification that describes how loud a speaker plays with a standardized input. Two subs of the same brand and power rating may have different sensitivities and one will play louder than the other. Yannick from Montreal / Canada Posted on 9/28/2015Hi, which setup is most powerfull with that amp;Sound Ordonance M-1500 (300 watts RMS x 1 at 4 ohms or 500 watts RMS x 1 at 2 ohms)1- One 12' sub single voice coil 4ohms (thats mean speaker will received 300w RMS)or2- One 12' sub DVC wired final at 2ohms (thats mean to me, each voice coil will received 250RMS).or3- One 12' sub single voice coil 2ohms ( mean spk will received 500RMS).Considering same brand and same watt speakerIs there a difference between number 2 and number3?Thanks!. Shawn from Brown Deer Posted on 9/6/2015I just bought a mono amp.it rating at 2ohms is 2200W x 1 ch. So do I want 1 or 2, SVC or dvc, 2ohm or 4ohm subs. My amp is 1 ohm stable. Do I take advantage of this?
Does 1 dvc 12' 2ohm sub sound same as two SVC 12' 4ohms wired parallel to 2ohm. This is so confusing. I have Boss AR3000D amp ran parallel to 2 12in. SVC 4ohm subs. Sounded real nice, but amp got hot. When I first put in amp I ran speaker outputs + to + and - to - ( 2speakers to one input) 4ohm load.
Amp didn't even get warm. I thought amps work better with least resistance? ( lower ohms). Thank you very much. I hope to hear from you soon. Ray from El Mirage Posted on 8/20/2015Same question right email sorry.Infinity.
1200 watt DVC UNSURE of internal wiring sealed box.When I bridge the sony 1000watt xplode it gets super hot. When using one channel I still get plenty of heat but will run all day. Update I tested ohm from the speaker leads disconnected from the amp I get 2.6 ohms???? What the hey?It sounds awesome I am just concerned about melting down something important. Yes I am running 4 gauge power and negative.
And very heavy speaker wire.Ideas?? Changes?This is the same Ray from a previous question I forgot 1 digit in my email!
Buck Pomerantz from Crutchfield Posted on 8/19/2015Andrew, You should not wire different impedance subwoofers together to the same amplifier channel because the lower impedance sub will get twice the power of the higher impedance sub, possibly under-powering one while over-powering the other. That's a recipe for blowing subwoofers. In your case, if that amp is a Sony XM-2200GTX, you could wire the DVC 2-ohm sub at to one channel of the amp, and the DVC 4-ohm sub at to the other. The DVC 2-ohm sub would receive 200 watts RMS and the DVC 4-ohm sub 250. Without knowing the RMS ratings of your subs, I can't tell you whether it would work or not.
John from los angeles Posted on 8/13/2015i have a 2003 bmw 3251 4dr. Running 3 amps Boss 200watt to run my front Kenwoods 51/2. I have a 1100watt/ 2 ohm stable mosfet boss amp running my 4 6 inch Lanzars at 300watts rms each running in series. Missing that UMFFF factor. So i recently purchased a 3000 watt Lanzar Amp with 2 Lanzar pro 10' at 1200 max each.
I forget the rms on them. I placed them in a ported box which took about half the space of my trunk A lot of rattling which shows its hitting but did not hear or feel a drastic change that i was expecting. Im thinking that its inclosed in the trunk the 4 6inch Lanzars are located in the car, 2 took place in the rear speakers near the rear window. And 2 i had customized myself and placed them in the middle of the rear seats.
What would be the best thing to do with all these since trying to make those 10's be heard would be slim to none because they are pretty much enclosed in the trunk. Can you mix match speakers with different wattage but the same ohmage? In other words running a PUNCH, KICKER, and a JLaudio 12'?. Brenda Flazer from Las vegas Posted on 8/8/2015Hi Buck Pomerantz, I have a question regarding the amp/seb setup i have going on right now.
I am working with a Insignia NS-A1200 amp which is a 1ohm mono channel amp. Using it to power 2 kicker CompR 12inch subs.
Which are the dual coil 2ohm subs. They are capable of switching to either 1ohm or 4ohm impedance. I am not getting the kind of sound i am looking for and these are brand new subs. I am concerned i am highly unpowering the subs. Can you please help me out with how it should be wired or maybe a proper amplifier?
Thanks a lot. Buck Pomerantz from Crutchfield Posted on 7/30/2015Jimmy, Rockford Fosgate P1 subwoofers come in DVC 2-ohm and DVC 4-ohm models, and it sounds like that for whichever ones you have, they're not wired to the amplifier correctly and its shutting itself off for self-protection.

Buck Pomerantz from Crutchfield Posted on 7/21/2015Zayjon, The problem isn't that you have different brand subs, it's that you have two different impedance subs.
A DVC 4-ohm sub can't have the same impedance and an SVC 4-ohm sub. You didn't mention how you're amplifying them, but you should never wire different impedance subwoofers together to the same amplifier. The lower impedance subs will get twice the power of the higher impedance subs, possibly under-powering one while over-powering the other.
That's a recipe for blowing subwoofers. Get separate amps for your different model subs. Kyle from South Africa Posted on 7/7/2015Hi. I have recently purchase x2 Targa 12' DVC 650wRMSx2 4ohm subs, in a SPL box, wired to 2ohms.
I am new to all of this sound stuff and I am wondering what amp to get to play them at their full potential. I was looking at getting the Targa Dynamite 2500wRMS Monoblock (2500wRMS @ 1ohm; 1700wRMS @ 2ohms; 1300wRMS @ 4ohms). What do you recommend is the best way to wire it to this amp or which is a better amp to get? Any help in this regard would be greatly appreciated.

Or will the amp do the same thing?. Chris from Sacramento Posted on 6/15/2015I just received some free alpine subs model (swe-10s4 4 ohm). I was looking for an amp when a friend mentioned he had one lying around. I asked for it and it turns out its a pioneer model (GM-7300M). There are two subs for this one amp and, according to my understanding, I might need a stronger amp.
I figured that might be a good option to wire them in. Would I be wrong in my assumption? That would make them 2ohm correct? I don't really know much about car audio and have only ever done home theater, so this is familiar but still unclear. Any and all suggestions help, thanks!
Links removed. Buck Pomerantz from Crutchfield Posted on 6/1/2015Jason, That is not the way a capacitor gets wired into a system. The cap should be located nearest the subwoofer amplifier, where it can do the most good restoring energy to the system when needed. The cap's positive terminal connects to the amp's positive power line and the cap's negative terminal connects to ground.
Be sure to follow the instructions that will come with your capacitor. As for fuses, in a multi-amp system, where the amps don't have their own onboard fuses, you should indeed fuse each amp's power line between the distribution block and the amp for safety.
And by the way, those subwoofers are each DVC 1-ohm, and two of them can only get wired together to form a 1/4-ohm, a 1-ohm, or a 4-ohm load. Jason from Commerce, TX Posted on 6/1/2015I just want to make sure I'm wiring everything up correctly. 2 Amps (Alpine MRX-F65, Alpine MRX-M110), 4 X Infinity Kappa 60.11CS 6-3/4' to each channel of the MRX-F65, Boss Audio 8 Farad Cap to the MRX-M110 and 2 X Kicker 40 CWRT101 (Wired in series to make a 2 Ohm Load on the amp in a sealed box).

Should the Cap be wired before all the Amps or just the one pushing the subs? And should I have a fuse near the amps in addition to the one near the battery? Here is a link to the wiring diagram I was thinking about. Link removed. Buck Pomerantz from Crutchfield Posted on 5/21/2015Devon, Giving an amplifier's make and model number help identify it much better than a jumble of specs, but I think you're talking about a Kenwood KAC-7201 2-channel amplifier. And the sub - is it an Alpine SWS-12D4?
If so, you have a classic case of trying to pair a 2-channel amplifier with a dual voice coil (DVC) 4-ohm subwoofer - they don't go together very well. The best you can do with that gear is to wire each voice coil separately to each output channel of the amp.
Make sure you keep the polarity of the wiring straight, and feed each channel the identical signal for input. Devon A from Saskatoon Sk. Posted on 5/21/2015I have been given a Kenwood amp, I'm not too knowledgable of the specs besides the basic numbers i've come across.Max Power Output 800 W × 1Rated Power OutputNormal (4 O) (20 Hz - 20 kHz, 0.08% THD) 150 W × 2Normal (4 O) (DIN: 45324, +B = 14.4V) 150 W × 2Normal (2 O) (1 kHz, 0.8% THD) 230 W × 2Bridged (4 O) (1 kHz, 0.8% THD) 460 W × 1.I have a alpine type S12 that says it runs 500w RMS (250 a coil) @ 4ohms.how would I make this work? Is it possible?. Buck Pomerantz from Crutchfield Posted on 4/27/2015Andrew, MTX Thunder 12' 4500 subwoofers came in two models - SVC 4-ohm and DVC 4-ohm. You should never connect subs of different impedances together to the same amplifier - the lower impedance subs will get more power than the higher impedance subs, resulting in unbalanced sound levels and potentially blown subs. If all three of yours are SVC 4-ohm models, I know of no way to safely wire them to that amplifier.
However, if all three of them are DVC 4-ohm subs, then they can safely get wired like.As far as sealed vs ported, check out for help deciding. That amplifier, however, does not have a subsonic filter, so it won't work well with a ported subwoofer enclosure. And there's no way to predict how angling the subs will affect the sound.
Experiment and report back with the results. Andrew Maloch from United States Posted on 4/26/2015i have a spl series 2 z2x-1600 1600 watt max mosfet 2 channel bridgable amp with 2 12'mtx thunder 4500 subs that are bridged.
I just got a 3rd sub that has the same 225rms as the mtx's. How can i wire these with out damaging anything, paralell or series? And when i go to make my box for them should i port it or seal it? And should i have my angles facing outward(so the 2 outside subs face away from each other) or inward( so the 2 outside subs angle towards each other)?
The problem with dual voice coil subs is that the amplifier must be able to drive the load. I am assuming that each coil is 2Ohms each and the amplifier you are driving the subwoofer with is capable of driving that load. If this assumption (of the VC) is true your Amplifier will need to power the 2Ohms of the VC this will be 'Normal'.
If the Amplifier is not capable of powering less than 4Ohms you will need to wire the subwoofer in 'Series'. If the Amplifier is capable of powering half the VC's resistance you can wire it in 'Parallel'. Normal wiring is going to be, Positive on the Amplifier goes to the Positive (red) side on the subwoofer and Negative on the Amplifier goes to the Negative (black) side on the subwoofer, then repeat this for the other output side of the Amplifier to the other VC, easy: This is 'Series'. Now if the amplifier is not capable of driving the load this gets slightly complicated. Positive from one of the positives on the amplifier goes to one positive side of the speaker.
Negative goes to the opposite coils Negative side (black), now you get a short wire of your preference from the Negative that has no other input and run it to the opposite Positive side that has no other input: This is called 'Parallel'. If the Amplifier is capable of running a load lower than the resistance rating of the subwoofer then run the wire from Positive on the Amplifier to Positive on the subwoofer and Negative on the Amplifier to Negative on the subwoofer, and then run a short wire of your preference from the first VC to the other VC, Positive to Positive and Negative to Negative. Double check the wiring Red to Red and Black to Black in everything but 'Series'.

Rockford Fosgate's DVC subs can handle lots of power, so you can enjoy bigger bassThe key difference between single and dual voice coil subwoofers is the multiple wiring options DVC subs offer:. Parallel: A dual 4-ohm voice coil subwoofer with its coils wired in parallel presents a 2-ohm load to your amplifier. Since an amplifier produces more wattage at a lower impedance, the parallel connection ensures you'll get the most output from your amp.
In the same fashion, if you have a stereo amplifier and two DVC subs, wire both subs for 2-ohm impedance (one per channel) for maximum output. Series: Series wiring lets you configure multiple woofers to one amplifier at an acceptable impedance. Wire both coils in series for an 8-ohm impedance, and then wire two 8-ohm subs together in parallel for 4-ohm total impedance (perfect for most 2-channel amps bridged to mono operation). Another example: if you have a high-powered 2-channel amplifier, wire four 8-ohm subs per channel (each channel sees a 2-ohm load). Independent: You can wire each voice coil to a separate channel of your amplifier, if you prefer not to bridge your amp. Independent wiring is a nice option if you're wiring two DVC subs to a 4-channel amplifier — one voice coil per channel. Just make sure the signal going to each coil is exactly the same, or the differences will cause distortion.DVCs and high-performance amplifiers. Look for an amp that's stable at 1 ohm, like this Rockford Fosgate T1000-1bdCP.Some amplifiers are designed with an unregulated power supply — these amps are favored by mobile audio competitors for their superior performance.
An unregulated amp's power increases dramatically when it sees a lower impedance load. For example, an amplifier that produces 75 watts RMS x 2 channels at 4 ohms would double its power to 150 watts x 2 with a 2-ohm load. DVC subwoofers (particularly the dual 2-ohm models) give you the flexibility to wring every bit of power out of this type of amplifier.Also, if you choose to add an unregulated amp as a power upgrade to your existing DVC subwoofer system, you can simply rewire your subs for optimum impedance. Remember that most car amps are stable down to 2 ohms in normal operation, and to 4 ohms in bridged mode.
It's important to check your amp's manual for its operating parameters before hooking up a DVC sub that's wired for low impedance.A DVC sub offers the same performance whether it's wired in series or parallel. Its power handling levels, frequency response, and other specifications do not change — the only difference is the impedance presented to the amplifier. As a result, you'll need to use the enclosure that's recommended for your sub, no matter how it's wired. Jesse from providence Posted on 8/4/2016ok so I have 2 rockford fosgate 12s svc with 250 rms and 8ohm ea. And also I have 2 mtx 10s dvc with 200rms 4ohm ea.

Dual Voice Coil Subwoofer Wiring
I cant think of how I could wire these to get to 2 ohm.I wasn't positive if I wired the 12s (8 ohm svc) in parallel and wired the 10s (4ohm dvc) in parallel, that will put the 12s at 4ohm and the 10s at 2 ohm,- is there a way to wire the sets together in parallel to get to 2ohm? If not what about 4ohm? And how would it b connected to the amp if either would work. Thanks in advance. Robert Ferency-Viars from Crutchfield Posted on 7/5/2016AV, if your receiver has a designated subwoofer preamp output, you should be using that. If it doesn't, then you should see if your receiver has switchable outputs on that rear channel. You can designate those switchable outputs for either full range signal (Rear setting) or for a subwoofer, which means they'll only send out bass frequencies (Sub setting).
If your receiver has neither, and the rear channel is only full range, then you should make sure to set the amp's crossover to Low-pass so that it will block the mids and highs. Anna Kiphuth from Buffalo Posted on 9/15/2015I have a boss mono amp 2800wt, cl D, 1 to 8ohms, 2 10in subs, 1100rms each, dvc 4ohm in a fitted sealed box, only.1cuft short on air space for speakers. Wired in parallel.
Had professional installed, had 2nd set of speakers burn up? All wires are doubled up, all neg from amp to speaker and same with pos.
All wiring diagrams show 1 leading to the other. ( 4 wires on amp pos/neg 2 leds to box port than doubled again to each coil 4 wires 2 leds each speaker.) amp has great THERMAL/OVERLOAD/SHORT PROTECTION, But why is this happining, seems like amp is hot and speakers are if course if buring up. About 80°+ outside, hot and it happens when i turn it up and use the power?
This amp was made for low Independence at 1ohms?.
You have two choices of how to wire this sub.First, is an 8 ohm load. This is called a series set up. Go from the positive of the amp to the positive of one voice coil. Then go from the negative of that voice coild to the positive of the other voice coil. Then go from the negative of that voice coil to the negative of the amp.Second is a 2 ohm load. This is called a parrallel set up. Go from the positive of the amp to the positive of both voice coils.
Then go from the negative of the amp to both negatives of both voice coils.Make sure your amp can handle a 2 ohm load. If you have two subs, you will need a 2 channel amp.Posted on Sep 03, 2011.
