How to Wire a Dual Voice Coil Subwoofer

A greater understanding of how to wire up a twin voice coil subwoofer can significantly improve listening enjoyment is necessary to unlock the full potential of your music library. To ensure that these potent speakers can handle all the power an amp can give without overloading them, prepare as we explore more in-depth details about this crucial feature by connecting one side with a positive and the other with a negative voltage.

You must first decide on the voice coil count and subwoofer type. You can get this information in the product’s handbook or by glancing at the subwoofer’s back. Additionally, you have all the required equipment, such as wire kits and connecting connectors. The wiring procedure should be started as your subwoofer, and its attachments have been recognized.

Why Is A Dual Voice Coil Subwoofer Necessary?

The single set of leads on a single voice coil subwoofer restricts its wiring options, but with twin voice coils, two sets are available to create a unique installation. It allows you to maximize power handling capabilities by matching various amplifier impedances. Dual voice coil subs are becoming common in automotive audio applications today, opening up different sound system design possibilities and enabling customers to create a uniquely personalized experience!

Choose which side of the subwoofer will be linked to a positive voltage and which one will be attached to a negative voltage first. Each coil’s resistance must be measured using an ohmmeter. Remember that the coil with the higher resistance will be on the negative side, and any wire with the same number of ohms as the coil with the lowest resistance will be on the positive side after this is finished.

After identifying both coils, the correct wiring harness needs to be connected to the subwoofer’s terminals. A spade connection is crimped onto each end of the wire before inserting into the matching terminal. To prevent short circuits, every crimp must be safe and insulated, just like any electrical job. After installing the wire harness, it’s time to connect the power supply to the subwoofer. The subwoofer’s positive terminal must first be connected to one of the cables from the positive side. A cable from the power source’s negative side should be connected to the subwoofer’s negative terminal.

Finally, any extras for a specific application should be included. Traditional audio gear may be used, so if necessary, as an amplifier or crossover. The subwoofer can now be tested to ensure that it operates once all wiring has been completed and double-checked.

Benefits of Dual Voice Coil Subwoofers

Dual voice coil woofers enable simultaneous connection of two amplifiers or receivers by allowing one woofer to power two independent channels. It expands the sound system’s customizability choices and makes adjusting the sound system simpler.

Dual-voice coil subwoofers may also go to even lower frequencies and are better able to handle bigger power outputs than traditional single-voice coil subwoofers. A dual voice coil system can produce a richer, more powerful sound with a bottom response. Finally, twin voice coils are fantastic for designing unique sound systems because they can generate multiple audio zones.

Overall, two voice coil subwoofers offer a wonderful solution for anyone trying to get the most out of their audio setup. Dual voice coil subwoofers are a terrific option for anyone wishing to update their sound system because of their increased power, deeper bass, and capacity for numerous audio zones.

How Do I Connect Two Dual Voice Coil Subwoofers?

Dual voice coil (DVC) subwoofers must be wired in series for the best audio quality because this increases impedance and ensures that power and voltage pass through without interruption. First, plug the amplifier’s positive output into Voice Coil 1’s positive lead to connect them. After that, join the negative leads of Voice Coils 1 and 2, and finally, join the negative end of Voice Coil 2 to the amplifier’s ground. You can begin to hear sounds with improved quality in just a few minutes.

How Can a Dual Voice Coil Subwoofer Be Parallel Wired?

Your dual voice coil (DVC) subwoofers should be connected in parallel if you want to increase power output and lower impedance. To begin, join the positive lead of Voice Coil 1 to the positive output of the amplifier. The negative lead of Voice Coil 1 and the positive lead of Voice Coil 2 should be connected to form a bridge. After that, attach the negative lead of Voice Coil 2 to the ground wire of the amplifier, and you’re ready to go.

If you wire them in parallel, your subwoofers will have twice the impedance but the same power output as a single-voice coil subwoofer. Your system has a more effective bass response and greater power handling capacity to this power and resistivity combination. Additionally, you can customize your audio experience by adjusting the low-pass filters on each subwoofer’s sound output. Finally, parallel wiring your subwoofers will save energy and enable you to achieve higher volume levels without increasing the amplifier’s wattage.

Building a multi-speaker system with both series and parallel wiring can be confusing. Sum the sets of three for an impedance total of 12 ohms, with each voice coil being a single 4 ohms. Suppose this group serves as one speaker connected in parallel. Further calculation informs us that 3 or 4 oscillations will likely occur while our amp produces 900 watts RMS into a four-ohm load. We can make decisions about the connections made by considering how many speakers are involved and their ensuing impedances. It requires greater amp power to ensure proper wattage and performance.

Safety Precautions

It’s important to consider system safety and use appropriate caution when working with electrical currents. Before plugging in any equipment or gadget, always verify the electrical connections. Before working on any electrical circuit, be sure the power is turned off. Always get professional advice if unsure of the wiring arrangement to ensure safe functioning and prevent any potential injury to your equipment or you. For instance, the total impedance is 12 ohms if three speakers are connected in series. It would require greater amp power to ensure proper wattage and performance.

A twin voice coil subwoofer should be wired parallel to provide the greatest possible sound flexibility. To ensure that your listening experience is uninterrupted, connect both coils so that you can continue to produce high-quality music even if one of them is damaged. Make sure to ground and secure all of your electrical connections properly. Electrical surges by faulty or loose wiring could harm your equipment or pose a safety risk. Check the impedance levels before connecting amplifiers and speakers. The sound quality may suffer noticeably or even worse if they aren’t compatible. You may design an audio system for any circumstance by keeping all these factors in mind.


What is the wiring for DVC subwoofers?

DVC subwoofers can be wired in various ways, including parallel, series, and dual mono configurations. The sound output and impedance are different for each wiring arrangement.

What are DVC subwoofers’ benefits?

DVC subwoofers have the benefits of increased sound output flexibility, power handling capacity, and the capacity to be wired in various ways to produce various sound outputs.

Do DVC subwoofers perform any better than standard SVC subwoofers?

It depends on the preferences and requirements you have in mind. SVC subwoofers may be more appropriate for those looking for a simpler setup than DVC subwoofers, which offer more flexibility and customization.


Traditional single-voice coil subwoofers are limited in their ability to be flexible and customized by dual-voice coil subwoofers for those looking to precisely tailor the output of their subwoofers to their personal preferences. The main benefit of using this kind of wiring is that it gives you more options for using the subwoofer. One voice coil, for instance, can still be used to generate sound if the other is damaged.
