Please explain. The voltage drop across the amp will be consistant with the voltage drop of every electrical device in the vehicle that draws from positive to ground. Some amps carry ratings at 12v and 14.4v, the power output at 14.4v is obviously higher, but the amp doesn't decide the voltage, the alternator/battery does.
