How to Wire Two Dual 2 ohm Subwoofers to a 2 ohm Impedance

Wiring two dual 2 ohm subwoofers to a final impedance of 2 ohms can be achieved by wiring the voice coils together in series/parallel.

This is a popular wiring method used because the subwoofers are able to maintain the stable 2 ohm impedance, while being able to receive more wattage from the amplifier than the conservative 4 ohm wiring configuration. The wiring method is also very simple to do by wiring the voice coils together in series and the subwoofers together in parallel.

Subwoofer Wiring Steps:

1Connect a positive terminal on sub 1 to a positive terminal on sub 2

2Connect a negative terminal on sub 1 to a negative terminal on sub 2

3Use a short wire jumper to connect the remaining positive terminal to the remaining negative terminal on sub 1

4Use a short wire jumper to connect the remaining positive terminal to the remaining negative terminal on sub 2

5Connect the positive terminal from step 1 to the amplifier terminal

6Connect the negative terminal from step 2 to the amplifier terminal

At this point you should have the two subwoofers connected together by a positive and negative terminal. This is wiring the subwoofers together in ‘parallel’. The jumper cable that connects the positive and negative terminals on each woofer is called wiring the voice coils in ‘series’. Together, this is called wiring in ‘series/parallel’ and is a great way to maintain two dual 2 ohm subwoofers at a 2 ohm final impedance.
