Power problems My amp will turn on when the car does, but then turns off again right after. I checked the fuse and all the wires and the only one I found a problem with was the remote wire. Should I replace the wire itself or is there something else that could be wrong?

What you need to check is weather or not the head unit is not at fault.to do this,remove the remote wire from your amp.then put a link wire from the main battery wire terminal on your amp accross onto the remote terminal so you are basicly joining the main power terminal and the remote together.if it then stays on,you have a fault with the head unit itsself.allso check that you are useing the remote output on your amp and not the electric areil wire.if you find it is the head unit at fault,its not a problem becouse all you have to do is find a switched power supply in the car and use that as your remote on/off switching,but ensure you put in a inline fuse near to the source of power rated at 10amps. I hope this solves your problem.
