Hi. Sitting with a weird problem with no known cause or fix. I've searched. My startsound 4 channel amp suddenly burned the mosfet power supply (2 mosfets of 4). I replaced the all 4 mosfets, installed the amp and it was playing good. When I switched of the head unit the mosfets burned. I replaced the mosfets and removed the remote wire from the amp. I connected a bridge from +12v to remote and it turned on an it played good. When I removed the bridge the same mosfets burned again. THe factory radio has a +12v out when headunit on so Im using that as remote turn on. Does anyone have any idea what could cause this? Regards
