Dual Voice Coil Sub Wiring Diagram. When it comes to wiring a dual voice coil subwoofer, knowing the correct diagram is crucial. Dual voice coil (DVC) subwoofers have two separate voice coils, each with its own set of terminals. This allows for different wiring options and the flexibility to match the subwoofer's impedance to the amplifier.. Dual voice coil speakers are extremely similar to single voice coil models except for having a 2nd voice coil winding, wire, and wire terminals. They both use a small gauge wire tightly wound on a speaker "bobbin" (tube) that rests inside a magnet attached to the cone. They produce sound when a musical signal is supplied.
