Tutorial: Wiring Dual Voice Coil (DVC) Subwoofer Drivers

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 FAQs.

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.
