Single Voice Coil Speakers
Single voice coil speakers have positive (+) and negative (-) terminals. Each will be connected to the positive (+) and negative (-) outputs of your radio (see diagram below).
If you are wiring just two speakers, remember to cap off the unused speaker wires.
Dual voice coil speakers
Dual voice coil speakers can be wired treating each voice coil as an individual speaker. This type of connection will give you the best sound possible.
Using the radio’s left and right front speaker outputs, connect the left positive (+) and negative (-) wires to one side of the dual voice coil speaker and the right positive and negative wires to the other (see diagram below).
