Understanding Dual Voice Coil Configuration A 4 ohm dual voice coil subwoofer features two separate voice coils, each with its own terminals, wired onto a single cone assembly. Safety is paramount; always disconnect the amplifier from power and remove the speaker wires from the back of the amp before touching any connections.

The key is that these coils can be wired in series or parallel, resulting in either 8 ohms or 2 ohms total impedance, depending on your amplifier needs. Series Wiring for Higher Impedance To wire the subwoofer in series, connect the positive terminal of your amplifier to the positive of the first coil.
This configuration adds the resistance of both coils, resulting in a total impedance of 8 ohms, which is ideal for protecting the amplifier while maintaining compatibility. This parallel wiring method drops the impedance to 2 ohms, allowing the amplifier to deliver more current and produce higher sound pressure levels, provided it is rated for such a low load.

Parallel Wiring for Lower Impedance For a lower overall load, connect the two positive terminals together and route them to the positive terminal of the amplifier. Simultaneously, connect the two negative terminals and route them to the negative terminal of the amp.
