Speaker sound fades in and out.

The sound frequently cuts to only the tweeter playing music very softly. If I hit the back component plate that houses the volume knobs, power plug-in, input/output, etc. it seems to sound normal again. Anyone know why?

could be the amp module going bad or the connection to the driver

From your description, I would expect to find a poor solder connection on the amp itself. If you can solder, remove the amp plate from the back and look at the connections. If any of the solder connections appear to have rings, resolder them

Let us know if you find anything and whether or not the resoldering resolves the problem.
