Report "I Have a audiobahn a1800dt its almost identical to this amp, i played it for a while with no problems, until i hooked up some crappy subs to it and it went into protection mode without comming out of it. All my grounds and power wires are 4 gauge and are properly connected....im sure it is probably a resistor on the output side, how can i check this and what resistor would i use to replace?"
