How to wire 2 dual 2 ohm voice coil subwoofers

Checkout our previous post on subwoofer wiring

In response to our blog post Subwoofer Impedance and amplifier output we filmed a video on some of the concepts contained in that post. As we showed in our subwoofer wiring diagrams you can present the amplifier with many different loads depending on how many voice coils and the impedance of those voice coils.

Wrong amplifier and subwoofers

In the example outlined in the video, we show you a hypothetical situation where we cannot connect the two subwoofers we have to the Rockford Fosgate PBR300X2 amplifier. This amplifier requires a two ohm load when bridged and there is no way we can create that load with our Pioneer TS-SW2002D2 8 inch low profile subwoofers. These Pioneer subwoofers are better suited for the Rockford Fosgate R500X1D amplifier as it can handle loads as low as 1 ohm.

8 ohm or 1 ohm subwoofer wiring

In the next segment we show you how to wire the Pioneer TS-SW2002D2 subwoofers as either an 8 ohm or 1 ohm load. By creating a 1 ohm load this makes them optimized from most class D mono subwoofer amplifiers.

See the products we used in this video:

Rockford Fosgate R500X1D 500 Watt Car amplifier
Rockford Fosgate PBR300X2 300 Watt Car amplifier
Pioneer TS-SW2002D2 8″ low-profile subwoofer

We show you how to wire two 8 inch subwoofers with dual 2 ohm voice coils to create an 8 ohm and 2 ohm load. We also show you how to check your subwoofer impedance. Please leave your comments and questions below.
