where are you getting the high level signal?
Does your car have 'premium sound'? ie: bose/monsoon/etc

First of all how exactly do you have your amp hooked up it sounded to me like it was ran off an LOC but if thats the case it would be low level not high so do you have RCAs plugged into the amp for your signal or just speaker wires and if it is speakers how does the LOC fit into the equation? It sounds like a ground problem or an RCA problem (if they are there) to me but a little more info would be helpful.
