Series Wiring Diagram

    Amplifier + ------------------> Coil 1 + 
                                     Coil 1 - ------------------> Coil 2 +
    Amplifier - ------------------> Coil 2 -

Parallel Wiring

Parallel wiring involves connecting both positive terminals to the amplifier’s positive and both negative terminals to the amplifier’s negative.

Benefits of Parallel Wiring

  • Decreases the overall impedance, allowing you to draw more power from your amplifier.
  • Provides a more explosive bass response, ideal for those looking to make a substantial impact with their sound system.

Parallel Wiring Diagram

    Amplifier + ------------------> Coil 1 + 
                                     Coil 2 + 
    Amplifier - ------------------> Coil 1 - 
                                     Coil 2 - 

Calculating Impedance

When wiring dual coil subwoofers, it’s vital to know the resultant impedance level based on your chosen wiring configuration:

  • Series Configuration:

Resultant impedance = Coil Impedance 1 + Coil Impedance 2

  • Parallel Configuration:

Resultant impedance = (Coil Impedance 1 * Coil Impedance 2) / (Coil Impedance 1 + Coil Impedance 2)

For example, if you have a dual coil 4-ohm subwoofer wired in parallel, the resultant impedance would be 2 ohms.
