Subwoofer Wiring

Subwoofer wiring is a VERY VERY important part of subwoofer installation. First of all, subwoofers either come in a single or dual voice coil (meaning it has one set of connectors or two). There two ways to wire a sub. Either in parrallel or in series. Parallel is connecting positive to positive and series would be going positve to negative.

Wiring your sub/subs in parralell will lower the ohm impedance while wiring in series will raise the impedance. In the picture above (referring to the JL W3v2, dual voice coil sub), you can see how wiring differently effects the final impedance. D6, D4, and D2 means 6, 4, or 2, dual voice coil subs. It's very important to know exactly how many ohms your subs are running at to ensure you give them the correct amount of power.
