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.

How to Wire a Dual 4 ohm Subwoofer to a 2 ohm Impedance

Wiring a single dual 4 ohm subwoofer to a final impedance of 2 ohms can be achieved wiring the voice coils together in parallel.

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 ‘parallel’ wiring and enables the dual 4 ohm subwoofer to achieve a 2 ohm final impedance.

This is a very common wiring method used for most single subwoofer installations because the 2 ohm load is stable, yet offers a fair amount of power.

Subwoofer Wiring Diagrams

The most important thing about installing a subwoofer is making sure that it is wired properly to the correct impedance. For the first time installer, it might seem like a tricky and confusing task, but in reality it is a really simple thing to do. If you know what wiring configuration you want to use, click on the link below for a diagram and explanation.

Subwoofer Wiring Recommendations

Not sure which to use? If you haven’t purchased your sub and amp yet, the following popular wiring configurations can help you in your buying process.

One subwoofer to Dual 2 ohm

This is my preferred method for a single subwoofer (and probably the most popular). Dual 4 ohm subwoofers are common and the simple wiring config down to 2 ohms provide a good balance for more power while still staying stable.

Two Subwoofers to Dual 2 ohm

When installing 2 subwoofers, I recommend maintaining a final impedance of 2 ohms. This is for the same reason as the one subwoofer to 2 ohm (more power and stable). This is done by getting two dual 2 ohm subwoofers and wiring them to 2 ohm.
