Thanks for your responses. If there are no pre amps, do you guys know what can be wrong. Right now he is running a prelude head unit, but it lights up amber as oppose to green and it doesn't have a clock, where a civic does. The reason why he is hooking up amps to the head unit is because he's already had 2 aftermarket head units stolen. And when putting back his stock one, his ground wire or power wire got loose (stupid installer cut his harness) touched the chasis. What do you guys think is or can be wrong? Oh and he says there wasa burn smell.

Thanks again
