When I move around with my spector ns2000, my amp puts out a really high pitched squeal, then it blows the tweeter protection bulb everytime. This has happened a couple of times. I have a GK 1001RB hooked up full-range to an Eden D210-MBX and a 1-15 cab. The amp doesn't even have to be turned up past 9 o'clock. Anybody got any ideas?
