Wiring your subs: Dual Voice Coils

With multi-driver sub systems, which often feature dual voice coils (DVC) on each driver, the level of wiring complexity can be enough to turn-off even the most adventurous of car audio do-it-yourselfers. Fear not though, for we have compiled wiring diagrams of several configurations for dual voice coil (DVC) drivers.

Please note that when wiring multiple drivers it is recommended that series connections between drivers be avoided at all costs. This does not include series connections made between voice coils on the same driver. For more information, please consult our dual voice coil tutorial.

Additionally, if you have an idea for a wiring configuration and you do not see it here, chances are you should re-think its implementation (in other words, don’t do it). You will more than likely find that the results will be less than optimal.

  1. I WANT TO KNOW HOW I CAN WIRE TWO 4 OHM (DVC) SUBWOOFERS TO HAVE AN 2OHM LOAD TO MY AMP.

    MY AMP IS 2 OHM STABLE

  2. Is it possible for me to wire…

  3. Wow, these diagrams are very helpful. Explained this way anyone could understand the best way to wire there subs. Many people do know that wiring your subs the wrong way can ruin the subs and the amplifier. But wiring them the correct way can increase performance exponentially. Most Subs nowadays are dual voice coil, so wiring them correctly is crucial.

  4. since seeing your page I will be trying to wire 6 dvc 4ohm subs. I want to know if my amp puts out 1600w rms at 1 ohm ,how many watts will I see running 1.3 ohm’s in series/parallel?

    • Just wire em up. If the the subs are 2 ohm and the amp is 2 ohm stable. you run it just like you would anything else. Positive from the sub to the amp. Negative from sub to amp. No extensive wiring needed!

  5. @Walter: Wire both subs in parallel, and then wire them in series to the amplifier. This will net you a 4Ohm load going into the amplifier. As long as you weren’t going to be pushing the amp with a 2Ohm load you should be fine. It will certainly limit the maximum output of the amp, but it will be plenty loud, and the extra resistance will add to the clarity of your Subs.

    @Jeremy: Wire both subs for parallel/parallel, this will net you an 8Ohm load, but unless you needed to fill a club or large hall there is still plenty of power for you to get what you need done.

    @ed Garcia: wire two sets of them in series, creating 8Ohms each, then wire those in parallel with each other. We should be down to a 4Ohm system plus the last sub. Wire the system and the last sub in parallel to the amp. This should net you (roughly) a 2Ohm load into the amplifier.

    @Richard: minimally less, somewhere around 1500 Watts.

    @Serafin: Drivers refer to the part of a speaker that actually creates the noise. Speakers are comprised of Drivers, a cabinet, andn sometimes some extra parts like crossovers, L-pads, etc.

    I hope this was helpful for all of you.

    I have a question, and it’s regarding what Walter has asked.
    you suggested wiring the subwoofers in parallel and then in series to the amp for a 4 OHM load with 2 4 OHM DVC Subwoofers.
    Would it be (At Least Theoretically) Possible to wire the subwoofers in series, and then in parallel to the amp to create a 2 OHM load?

    The idea has been bouncing around in my head as to this possibly working, but have not been able to find anything that could back it up.

    I want to know if I happen to be on to something, or if i’m losing my mind over this.

  7. I got a dual voice coil 2ohm sub and a 2ohm amp. Would I have to wire the two voice coils together (series) or´╗┐ do I just wire one coil to the amp since its rated at 2ohms? I want it all in 2ohms but not sure if both voice coils has to be wired and which way should it wired for 2 ohms

    I got the Pioneer TS-W308D2 subwoofer

    Kicker ZX400.1 Amp

    thanks

  9. ive got six re audio 15s that are dual voice coils and 4 ohms each. is there a way i can wire them to one amp with out them over heating?

  10. This diagram really helped me! I have 2 12 inch dual 4 ohm Boss 2300 watt subs with kicker kx1200.1 mono, 1 ohm stable!!!! My shit SLAPP HARD!!!

  11. is there an advantage to running my amp at 2ohms instead of 0.5ohms.

    i want to wire 2 DVC 2ohm 900rms soundstream tarantula T5-12′s to a soundstream tarantula TX1.2600d (still would have to purchase) which has 2600rms at 0.5ohm or 1200rms at 2ohm. obviously at 2ohm there is no where near enough power (600rms short)

    i currently have a soundstream tarantula TX1.2000D but that can “only” be run at 4/2/or 1 ohms according to the website. if i wire this at 0.5ohms will that ruin either my subs or the amp??

  12. I think this is among the so much significant information for me. And i’m satisfied reading your article. However wanna remark on some normal issues, The site style is wonderful, the articles is truly nice : D. Just right task, cheers

  13. I want to know if I can wire 2DVC 4ohm subs into a 2ohm load?

    If I wire each subwoofer sepratly into a 2ohm load, then connect them both into the same amp output, would this work?

    please email paulyjohn94@gmail.com ASAP

    thanks!
