Hi I have 2 amps being run from my head unit. The one for the subwoofer is ok as the sub is powering up and working. But the 4 channel amp has stopped working for some reason. I've had to remove a lot of rear trim to gain access to it but can't see anything obvious. There is power to the amp, there remote lead is powering up (live with tester) but the light on the amp is not coming on and so the speakers not working.
I have just tried with a different amp and the same thing is happening. Both the 12v and remote connections have power but the amp light is not on and no resulting sound. Don't know why the sub amp is working though.
The head unit has not been touched and the RCA's are all intact.
What else could be the problem as the car is in bits right now.
Thanks in advance.
