there must be a short. hook the power amp up to a power supply or another battery,fused of course...if it works,it is ok.
then the problem is in the car
high power amplifiers should be run off a secondary battery.
a 480 watt amplifier will pull 40 amps of current. enough to run 8 headlights.the real problem is surge currents,which the spikes can damage the alternator/regulator.these can top 100 amps.
some high end installs use a second alternator and battery.
