Single Voice Coil (SVC) Wiring Tutorial

With multi-driver sub systems, 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 single voice coil (SVC) 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 section. Additionally, if the user has an idea for a wiring configuration that is not seen here, the user should re-think its implementation (in other words, don’t do it). Most likely, the results will be less than optimal.
