there is a Remote turn on wire, on the back of the head unit, take this wire an run to the RMT connector on the amp. Run a ground wire from the amp to a good ground ponit. also run a power (+) wire from the battery to the amp. you need to hook a fusealbe link from the battery to the amp on the (+) wire. If your lights an stuff dim when the subs hit hard, u will need to get a capicator like the one in the pic attached. From the amp hook the subs up to the speaker out for the left and right. You will also need to run a RCA cable from the back of the head unit to the amp. This is Audio Left (White) and Audio Right (Red). hope this helps
