Dual 1 Ohm Wiring Diagram: Everything You Need to Know

When it comes to car audio systems, wiring can be confusing and overwhelming, especially for beginners. One of the most popular wiring configurations is the dual 1 ohm setup, which allows for flexibility and customization in your system. In this article, we will be discussing the basics of dual 1 ohm wiring diagram and how to install it in your car.

What is Dual 1 Ohm Wiring Diagram?

Dual 1 ohm wiring diagram is a configuration that allows for two subwoofers with a 1 ohm impedance each to be wired together in parallel or series. This wiring setup provides flexibility in terms of the overall impedance of the system, allowing for a range of amplifier options and output possibilities.

Parallel wiring involves connecting the positive terminals of each subwoofer together and the negative terminals together, resulting in a total impedance of half of each subwoofer’s individual impedance. For example, two 1 ohm subwoofers wired in parallel would result in a total impedance of 0.5 ohms.

Series wiring involves connecting the positive terminal of one subwoofer to the negative terminal of the other subwoofer and the remaining positive and negative terminals to the amplifier, resulting in a total impedance that is the sum of each subwoofer’s individual impedance. For example, two 1 ohm subwoofers wired in series would result in a total impedance of 2 ohms.

How to Wire Dual 1 Ohm Subwoofers

Wiring dual 1 ohm subwoofers requires careful planning and attention to detail. Here are three common wiring options:

Option 1: Parallel Wiring

Subwoofer Terminal Wire Color Amplifier Connection
Subwoofer 1 Positive (+) Red Amplifier Positive (+)
Subwoofer 1 Negative (-) Black Amplifier Negative (-)
Subwoofer 2 Positive (+) Red Amplifier Positive (+)
Subwoofer 2 Negative (-) Black Amplifier Negative (-)

The total impedance of this setup will be 0.5 ohms, which is very low and requires an amplifier that can handle this load. Make sure to check your amplifier’s specifications before using this wiring option.

Option 2: Series Wiring

Subwoofer Terminal Wire Color Amplifier Connection
Subwoofer 1 Positive (+) Red Subwoofer 2 Negative (-)
Subwoofer 2 Positive (+) Red Amplifier Positive (+)
Subwoofer 1 Negative (-) Black Amplifier Negative (-)
Subwoofer 2 Negative (-) Black Subwoofer 1 Positive (+)

The total impedance of this setup will be 2 ohms, which is a common load for many amplifiers. It provides a good balance between power and electrical strain on the system.

Option 3: Dual Amplifier Wiring

If you have two amplifiers, each capable of handling a 1 ohm load, you can wire each subwoofer to a separate amplifier, resulting in a total load of 1 ohm. This allows for even more power and control over your system.

FAQs

1. Can I wire dual 1 ohm subwoofers to a 4 ohm amplifier?

Yes, you can wire dual 1 ohm subwoofers to a 4 ohm amplifier by wiring them in series. This will result in a total impedance of 2 ohms, which is compatible with most 4 ohm amplifiers.

2. Can I wire dual 1 ohm subwoofers to a 2 ohm amplifier?

Yes, you can wire dual 1 ohm subwoofers to a 2 ohm amplifier by wiring them in parallel. This will result in a total impedance of 0.5 ohms, which may overload the amplifier. Make sure to check your amplifier’s specifications before using this wiring option.

3. Can I wire dual 1 ohm subwoofers to a mono amplifier?

Yes, you can wire dual 1 ohm subwoofers to a mono amplifier. Just make sure to choose a mono amplifier that is compatible with the total impedance of your wiring setup and provides enough power for your subwoofers.

4. Can I wire dual 1 ohm subwoofers in a sealed or ported enclosure?

Yes, you can wire dual 1 ohm subwoofers in both sealed and ported enclosures. The enclosure type will affect the sound and performance of your subwoofers, so make sure to choose the right type for your preferences and goals.

5. Can I wire dual 1 ohm subwoofers with different brands or models?

Yes, you can wire dual 1 ohm subwoofers with different brands or models, as long as their specifications and impedance match. It’s important to do your research and make sure the subwoofers are compatible before wiring them together.

Conclusion

Dual 1 ohm wiring diagram is a popular and versatile option for car audio enthusiasts who want to customize and optimize their system. With the right knowledge and tools, you can wire dual 1 ohm subwoofers to achieve the sound and power you desire. Just remember to follow safety guidelines, double-check your wiring connections, and choose the right amplifier for your setup.
