Dual Voice Coil Wiring Diagram: Everything You Need to Know

If you’re interested in car audio, you’ve probably heard of dual voice coil (DVC) speakers, and for good reason. DVC speakers provide more installation flexibility and better performance than single voice coil (SVC) speakers. However, wiring a DVC speaker can be confusing, especially if you’re new to car audio. In this article, we’ll explain what DVC speakers are and how to wire them to get the most out of your car audio system.

What is a Dual Voice Coil Speaker?

A DVC speaker is a speaker with two independent voice coils, each with its own set of connections. Unlike SVC speakers, which only have one voice coil and one set of connections, DVC speakers can be wired in a variety of configurations, including series, parallel, and independent.

DVC speakers are typically used in car audio systems because they provide more installation flexibility than SVC speakers. With a DVC speaker, you can wire it to a 1-ohm or 4-ohm load, which allows you to match the speaker to your amplifier’s output impedance. Additionally, DVC speakers allow you to create a multi-speaker system by wiring two or more speakers together in parallel or series.

How to Wire a Dual Voice Coil Speaker

Wiring a DVC speaker is not difficult, but it can be confusing if you’re new to car audio. To wire a DVC speaker, you’ll need to know the speaker’s impedance and the impedance of your amplifier. You’ll also need to decide how you want to wire the speaker, whether in series, parallel, or independent.

Series Wiring

In series wiring, you connect the positive terminal of one voice coil to the negative terminal of the other voice coil, and then connect the remaining positive and negative terminals to your amplifier. This configuration increases the speaker’s impedance, which means that it will draw less power from your amplifier. However, it also reduces the speaker’s output power and can decrease its frequency response.

Parallel Wiring

In parallel wiring, you connect the positive terminals of both voice coils together and the negative terminals together, and then connect the remaining positive and negative terminals to your amplifier. This configuration decreases the speaker’s impedance, which means that it will draw more power from your amplifier. However, it also increases the speaker’s output power and can improve its frequency response.

Independent Wiring

In independent wiring, you wire each voice coil to a separate channel on your amplifier. This configuration allows you to control the volume and frequency response of each voice coil independently, which can improve the overall sound quality of your system. However, it requires a multi-channel amplifier and can be more difficult to set up.

FAQ

Question Answer
What’s the difference between a DVC speaker and an SVC speaker? A DVC speaker has two independent voice coils, while an SVC speaker has only one.
What are the advantages of a DVC speaker? DVC speakers provide more installation flexibility and better performance than SVC speakers.
What impedance should I wire my DVC speaker to? You should match the speaker’s impedance to your amplifier’s output impedance.
How do I wire two DVC speakers together? You can wire two DVC speakers together in parallel or series, depending on your desired impedance and power handling.

Conclusion

Dual voice coil speakers are a popular choice for car audio enthusiasts because of their flexibility and performance. Wiring a DVC speaker can be confusing, but with a little knowledge and the right tools, you can get the most out of your car audio system. Whether you’re wiring your speakers in series, parallel, or independent, make sure to match the speaker’s impedance to your amplifier’s output impedance to get the best performance possible.
