Wolf, I read your replies in your "Aftermarket Cruise Up And Running" thread but I decided it was more appropriate to add my reply here since it applied to the OEM unit.
I pulled my amp out and took the circuit board out of the box. I went over each soldered joint today with a circuit tester and found they were all good and there weren't any shorts either. It looks like I will have to check each individual component but I have no idea how I will check the IC's since my knowledge of electronics stops there.
I know it would be easier to go the aftermarket route but I have this thing about trying to keep a car all original, except for car audio systems but even there I won't cut interior panels to fit speakers.
