So I had a dual400w amp with 2 twelves but today I connected a 750w pioneer. Bass was definatly hitting harder. But I turned the volume up a little and everything quit. Fuses still look good on amp and radio. But the radio is dead, along withthe amp, information display above the radio is just red, and climate control display is blank. Anyone know anything to try to get this stuff working again?? 1998 gtp
