dual VOICE coil wiring

FOR SUBWOOFERS AND OTHER SPEAKERS

When it comes to wiring dual coil subwoofers, choosing the right configuration can significantly impact your system's performance. This post covers the most common wiring methods: series, parallel, and independent coil setups. Each approach affects impedance, power handling, and overall sound quality, and the guide provides clear, easy-to-follow diagrams for each configuration.

1. Parallel Wiring
Parallel wiring lowers the impedance, allowing the amplifier to output more power. This configuration connects each coil's positive and negative terminals, halving the impedance (e.g., two 4-ohm coils become a 2-ohm load). It's a great option for maximizing output but requires an amplifier to handle the reduced impedance.

2. Series Wiring
Series wiring combines the coils' impedance, resulting in a higher ohm load. This setup is ideal for those seeking stable, efficient power delivery from the amplifier. By wiring the coils in series, you effectively double the impedance (e.g., two 2-ohm coils become a 4-ohm load), which can benefit matching amplifier capabilities.

3. Independent Wiring
This method uses each coil independently, offering flexibility in multi-subwoofer setups. Independent wiring lets you connect each coil to a separate amplifier channel, enabling precise control over each subwoofer’s output for balanced performance.

Tips for Best Results

  • Match the wiring setup to your amplifier’s capabilities for the best performance.

  • Always use quality wiring and connections to ensure reliability and efficiency.

  • Consult the manufacturer's specifications for your subwoofers and amplifiers to optimize the configuration.

By understanding these wiring methods, you can tailor your setup to achieve the best sound quality and bass performance in your vehicle. Dive into the diagrams and get the most out of your dual coil subwoofers!
