When it comes to car audio systems, subwoofers play a crucial role in delivering that deep, rumbling bass that gets our hearts racing. But what happens when you’re dealing with a dual voice coil (DVC) subwoofer, and you’re not sure how to wire it up? Can you hook up just one side of the DVC subwoofer, or do you need to connect both voices? In this article, we’ll delve into the world of DVC subwoofers, explore the benefits and limitations of hooking up one side, and provide you with a comprehensive guide to get you started.
What is a Dual Voice Coil Subwoofer?
Before we dive into the meat of the topic, let’s take a step back and understand what a DVC subwoofer is. A DVC subwoofer features two voice coils, each connected to a separate terminal on the subwoofer. This design allows for greater flexibility when it comes to wiring and impedance matching. Each voice coil has its own set of wires and terminals, usually labeled as “+” and “-“.
In a typical single voice coil (SVC) subwoofer, there’s only one coil and one set of terminals. DVC subwoofers, on the other hand, offer more wiring options, which can be beneficial in certain situations.
The Benefits of Hooking Up One Side of a DVC Sub
So, can you hook up just one side of a DVC subwoofer? The short answer is yes, you can. Here are some benefits of doing so:
Simplified Wiring
One of the most significant advantages of hooking up one side of a DVC sub is the simplified wiring process. With only one voice coil connected, you’ll have fewer wires to deal with, making the installation process less complicated.
Easier Impedance Matching
When you hook up one side of a DVC sub, you can easily match the impedance of your amplifier to the subwoofer. This is because the impedance of a single voice coil is typically half that of the entire subwoofer.
Increased Power Handling
By only using one voice coil, you can increase the power handling of your subwoofer. This is because the power is distributed across a single coil, rather than being split between two coils.
The Limitations of Hooking Up One Side of a DVC Sub
While hooking up one side of a DVC subwoofer has its benefits, there are also some limitations to consider:
Reduced Performance
The most significant limitation of hooking up one side of a DVC sub is reduced performance. By only using one voice coil, you’ll be sacrificing some of the subwoofer’s overall power and sound quality.
Unbalanced Sound
When you hook up one side of a DVC sub, the sound can become unbalanced, with some frequencies dominating others. This can result in a less-than-ideal listening experience.
Reduced Efficiency
Using only one voice coil can reduce the efficiency of your subwoofer. This means that more power will be wasted as heat, rather than being converted into sound energy.
Wiring Options for a DVC Subwoofer
Now that we’ve discussed the benefits and limitations of hooking up one side of a DVC sub, let’s explore the different wiring options available:
Series Wiring
In series wiring, both voice coils are connected in series, with the positive terminal of one coil connected to the negative terminal of the other coil. This wiring configuration results in a higher impedance and a higher power rating.
Parallel Wiring
In parallel wiring, both voice coils are connected in parallel, with the positive terminals connected together and the negative terminals connected together. This wiring configuration results in a lower impedance and a lower power rating.
Independent Wiring
Independent wiring involves connecting each voice coil to a separate amplifier channel. This wiring configuration offers the most flexibility and allows for the most precise control over the subwoofer’s performance.

Can I Hook Up One Side of a Dual Voice Coil Sub?
Yes, it is possible to hook up one side of a dual voice coil sub, but it’s essential to understand the implications and potential consequences. A dual voice coil sub has two coils, each with its own set of terminals, allowing for greater flexibility and wiring options.
When you only hook up one side, you’re essentially using the sub as a single voice coil sub. This means you’ll only be utilizing half of the sub’s potential power handling, which can affect its overall performance. Additionally, you may need to adjust the impedance and wiring configuration to ensure the sub is receiving the correct signal.
Will Hooking Up One Side of a Dual Voice Coil Sub Affect the Sound Quality?
Hooking up one side of a dual voice coil sub can affect the sound quality, but the extent of the impact depends on various factors. If you’re using a high-quality sub with a well-designed dual voice coil configuration, the difference might be minimal. However, you may notice a slight decrease in bass response and overall efficiency.
The reason for this is that dual voice coils are designed to work together to provide a more even and balanced sound. By only using one side, you’re disrupting this balance, which can lead to a less accurate and less detailed sound reproduction. Nevertheless, the impact might be negligible if you’re using a high-quality sub and a well-tuned system.
Do I Need to Adjust the Impedance When Hooking Up One Side of a Dual Voice Coil Sub?
Yes, adjusting the impedance is crucial when hooking up one side of a dual voice coil sub. Dual voice coil subs typically have a lower impedance than single voice coil subs, and hooking up only one side can alter the impedance. Failing to adjust the impedance can result in reduced power handling, decreased efficiency, and potentially even damage to your amplifier or sub.
To ensure proper impedance matching, consult your sub’s documentation or manufacturer’s recommendations for single-coil operation. You may need to use a different wiring configuration or adjust the amplifier’s settings to accommodate the changed impedance. It’s essential to take the time to get this right to ensure optimal performance and safety.
Can I Wire a Dual Voice Coil Sub in Series or Parallel?
