Sounds like the Amp is responding to the power surges of the lights/appliances draw on the circuits. I suspect a surge supressor will help, if not eliminate this problem. I would recommend any of the brand name ones ie. Belkin, APC etc. You could always spring for a PF60 or the like, for some added cool factor .
