The amps channel 3 and 4 are buzzing really loud and then the amp shuts off in to protection mode.... I disconnected those 2 speakers and the amplifier works fine bu channels 1 and 2 every once in a blue moon will go very very low almost inaudible and then back to normal voume after a few seconds and it will repeat it a few times and then just operate normally....anyone have any vlues what this could be, I havent opened it up yet to check the gains and crossovers controls that are on top to make sure they havent come lose or anything.. stupid people stepped all over the top mounted controls. thanks all help is appreciated..
