hmm a wireing kit would be a start. You need a power wire a ground wire remote wire rca's and some speaker wire. The power wire goes from the + on the bat to the amp and the ground goes to the frame of the car to the amp. The remote wire goes from your HU to the amp. You also need some rca cables that r gonna go from the HU to the amp. Then your gonna need some speaker wire from the amp to the subs. I read somewhere you could use welding cable from www.weldingsupply.com as power and ground wire. Never used it but maybe someone here has ?
