I'd check that the patch cables. I've had this happen to me before when installing Zapco amps. The signal was just too "HOT" and it burned up the patch cables. Do you have another set to use? Also, have you noticed if your amp was running hot? How is the load on it? The impedance on the speakers aren't overworking the amp is it? This will cause clipping...as well as possible permanent damage.
