Plug the RCA cables into the appropriate RCA outputs on your stereo. Run these wires, the turn-on wire, and the RCA cable, down the opposite side of the car from the power wire.

What’s the best way to adjust a subwoofer?
Adjust your receiver’s bass tone control to its middle, zero, or “flat” setting, whichever it’s called on your stereo. If it has a subwoofer level control, set it, also, to its middle, or “no gain” setting. Sometimes receivers have a crossover, low-pass filter, or bass boost on their subwoofer output. Make sure those are all turned off, too.
