I have no idea what to do. I'm using the amp in 2 channel mode so I'm only using the front RCA inputs. Both of them wiggle a bit. When in the rest position, the amp hums and popps. When I spread the 2 plugs apart, the amp plays fine.

Since the amp is well out of its warranty, I finally opened it up for the first time. There is an assembly of the 4 input/2 output rcas on a piece of white plastic. The connection where the assembly meets the main board appears to be very solid. However, I cannot see inside this assembly to see where there is a loose connection.

Any suggestions? I really don't want to send it to RF cuz there's NO way I can afford to get it fixed...
