Delving into the world of audio systems, it’s essential to understand the basics of a dual voice coil subwoofer. These devices offer superior flexibility and sound quality. They have been game-changers in the audio industry, particularly due to their versatility and the enhanced sound quality they deliver.

A dual voice coil subwoofer consists of two voice coils wound on the same cylinder, connected to the cone. This unique structure allows for a variety of wiring options, opening up a plethora of possibilities for audio enthusiasts. You can wire a DVC sub in several ways, depending on your sound system’s requirements.

The flexibility extends to impedance options as well. A 4-ohm DVC subwoofer provides more wiring flexibility, suitable for users who may want to upgrade their system in the future. In contrast, a 2-ohm DVC subwoofer is ideal for maximizing amplifier power and delivering punchier bass.

Wiring Configurations for Dual Voice Coil Subwoofers

Understanding the different wiring configurations for svc and DVC subwoofers is crucial, as each setup can significantly impact your car audio experience. We’ll guide you through the most common wiring options: Series, Parallel, and Combination wiring.

  • Series Wiring: This configuration involves connecting the coils sequentially. If you’re using a 4-ohm DVC subwoofer, series wiring will increase the overall impedance to 8 ohms. This setup is ideal if you’re aiming for a less power-demanding, more relaxed sound output.
  • Parallel Wiring: Here, as seen by the amplifier, the coils are wired side by side, reducing total impedance. For instance, a 2-ohm DVC subwoofer will drop to 1 ohm in parallel wiring. This option gives you louder, more vibrant beats but requires more power from your amplifier.
  • Combination Wiring: For multiple subwoofers, a combination of series and parallel wiring provides the most flexibility. This setup allows you to balance power demand and sound output to meet your specific needs.

Calculating Total Load and Impedance for Dual Voice Coil Subwoofers

Calculating the total load and impedance for DVC subwoofers might seem complex, but with a bit of understanding and practice, it becomes straightforward. The total load, for instance an 8 ohm load or a 2 ohm load, refers to the overall power that the subwoofer system can handle, and impedance is a measurement of the resistance to the flow of an electric current.

In a series wiring setup, the impedance for DVC subwoofers adds up. For instance, if each coil has an impedance of 4 ohms, the total impedance in a series setup would be 8 ohms – this ohm rating is important.

In a parallel configuration, the total impedance is divided by the number of coils. For example, when wiring a dual 4 ohm subwoofer in a parallel setup, the connection between the same 4-ohm coils would result in a total impedance of 2 ohms. This understanding is key to optimizing your sound system’s performance, ensuring that you’re not overloading or underpowering your system, which could result in poor sound quality or damage.

Wiring Dual Voice Coil Subwoofers to Amplifiers and Receivers

Step-by-step wiring DVC subwoofers to amplifiers, receivers, vibrant colors.

The goal of wiring DVC subwoofers to amplifiers and receivers is to ensure the subwoofer’s ohm load matches the output impedance of the amplifier, a key factor in maximizing performance and preventing equipment damage.

  • First, identify the impedance of the DVC subwoofers and the amplifier’s output impedance. They should match or be within a safe range of each other.
  • Next, wire the DVC sub to the amplifier, ensuring positive to positive and negative to negative connections.
  • Finally, double-check connections for tightness and correct polarity before switching on the system.

Can I Apply the Same Wiring Techniques from a Light Switch to Wiring a Dual Voice Coil Subwoofer?

Yes, you can apply the same wiring techniques from wiring a 3 gang switch to wiring a dual voice coil subwoofer. Both require understanding how to connect multiple sources to a single output, making the principles of wiring transferable between the two applications.

Troubleshooting and Common Issues with Dual Voice Coil Subwoofers

Despite our best efforts, we might encounter common issues that need troubleshooting, particularly when dealing with impedance mismatches in dual voice coil speakers and their effects on performance.

Incorrect wiring can result in suboptimal sound quality or even damage to the subwoofers. A common mistake is wiring the voice coils in series when they should be in parallel, or vice versa. This not only affects power handling but also impacts overall sound quality.

Imbalance in power distribution is a common issue, especially in car audio systems involving svc subwoofers. If power isn’t evenly distributed across the terminals of the dual voice coil speakers, it can lead to sound distortion or inconsistency.

Overloading, leading to a blown subwoofer, often happens when the power output from the amplifier exceeds the power handling capacity of the ohm dual voice coil speakers. The key is to ensure the amp’s power doesn’t exceed the sub’s RMS rating.


We’ve walked you through the basics of wiring a dual voice coil sub, different configurations, and how to calculate total load and impedance.

We’ve also touched on how to wire them in series using the correct gauge wire in the process of creating a subwoofer enclosure. wiring them to amplifiers and receivers.

We hope this manual has cleared up any confusion you might’ve had about wiring single voice coil subwoofers.

But remember, if the coils are wired in series or parallel and you encounter any issues, don’t hesitate to refer back to our troubleshooting guide.

Wiring a DVC sub can be intricate, but with patience, it’s entirely manageable.
