Can you direct message me? I’ve just picked up this exact setup and need a little insight on how you wired the amp in. I know virtually nothing about radio equipment and wiring.
Wiring the amp is simple. You run a cable coming from the positive terminal on the battery (with an inline fuse) going to the amp. Then you should have a set of RCA cables that go from the back of your aftermarket headunit to the RCA cable inputs on the amp.
You then of course have a ground wire going from the amp to the body of the vehicle, and then you have wires going from the amp to the subwoofer itself as well.
Very easy to do, but it does of course require at least some basic knowledge of wiring.
