On the panels I've seen- there are white/Neutral buses down each side (for all white wires only). The bare ground wires have their own bus on one side or the other. These should be separate as Jakewash said. *** So, not only should the white and bare wires not share the same screw, they should not share the same bus either ***.
It should be apparent from looking in the panel that the white and bare ground wires are kept on separate bus connecting bars. Does this look like what you see? If you have a white or ground out of place you should be able to correct that.
What did you think of trying the amp at a friends or neighbors? I know it's a pain- but I would hate to see you rewire your entire house and find out it was the amp. I would first separate the grounds and neutrals however, as they may be the problem, and should be separate anyways.
Good luck.
