datzenmike Posted May 29, 2016 Report Share Posted May 29, 2016 Wire the radio to the accessory side of the fuse box. Usually the radio tells the amp to turn on so a switch isn't necessary. You will need a heavier cable for power to the amp. This cable must have a fuse at the battery end. 1 Quote Link to comment
Scgreen620 Posted May 29, 2016 Author Report Share Posted May 29, 2016 So the accessory fuse will turn the radio on when the car runs or will it keep it on at all times? 1 Quote Link to comment
datzenmike Posted May 30, 2016 Report Share Posted May 30, 2016 Accessory will turn on/off with the key. This way you don't have to remember to turn it off. Most units have a send wire to the amp to tell it to turn on when it does. This way everything shuts off with the key. 1 Quote Link to comment
