I got this amp in for repair .
The owner stated that the amp makes the subwoofer flutter he said the amp doesn’t do it all the time more like 80% of the time is does this then the other 20% the amp works perfectly fine .
He said that there are 4 other amps in the system and they all work perfectly fine .
So I’m assuming this is not a broken rca ground inside the head unit .
Any ideas on what to check in this amp since everything I’ve checked so far appears normal

The RCA jacks are a good place to start. Also try twisting the transformers and inductors.
Other than that, push on various parts of the board to see if you can reproduce the problem.
