PowerBass ASA-600.4
I just bought this amp with channels one and two blown. the kid was bridging and running subs and thats all i know. now all 4 channels work perfect at really low volume. as soon as you turn it up one and two will cut and go into protection mode. I am going to go with blown outputs on one and two? any input please. also nothing looks burned.
