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.

How to Wire a Dual 2 ohm Subwoofer to a 1 ohm Impedance

Dual 2 ohm Subwoofer Wired to 1 ohm

Wiring a dual 2 ohm subwoofer to a final impedance of 1 ohms can be achieved wiring the voice coils together in parallel.

This is a very common wiring method used by those that really want to push their subwoofer and amp to the limits for heavy bass. Since the 1 ohm final impedance is not as stable as 2 ohm or 4 ohm configurations, it is commonly recommended by professionals to only wire to a single ohm for you know what you are doing.

Subwoofer Wiring Steps:

1Connect both positive terminals on the subwoofer

2Connect both negative terminals on the subwoofer

3Connect a positive subwoofer terminal to the positive terminal on the box

4Connect a negative subwoofer terminal to the negative terminal on the box

At this point you should have all the postive terminals connected together and all the negative terminals wired together. This method is called ‘series’ wiring and enables the dual 2 ohm subwoofer to achieve a 1 ohm final impedance.
