Depends what your hooking up.. To hook up subs with and amp you simply have 2 4 gauge wires. RCA WIRES, RECEIVING WIRE AND SPEAKER WIRE.. With one of the 4 gauge ires, you need to ground it.. Screwing it into something is the best way to ground this. Then you need to find a good place to hide the wires.. You can run them along the doors underneath the carpet.. Then after you run the wires you have to put the 4 gauge wire from the amp to the battery. Thee should be a hole underneath the dashboard, if not you can make one yourself. Then the RCA cables and receiving wire needs to be un to the CD player. Connect the wires to the amp and the speaker wires to the subs and turn it on..
