[QUOTE="Djltoronto, post: 7152123, member: 628222"] If both amps are class A/B - both amps will draw very close to the same current from the cars electrical system. So if you have a 500Wrms amp running at 500w, and for the sake of the argument lets say this amp is 50% efficient - 1000w will be drawn from the cars electrical system. if you have a 1000Wrms amplifier and adjust the volume so that it's outputing the same as the 500w amp above, and lets say this amp is also 50% efficient, the draw on the electrical system will still be 1000w.. The difference is, the 1000Wrms amp will never get as hot, as it will have a heatsink designed to dissapate more heat, but the electrical load will still remain the same when the output volumes (or output wattage) remains the same when comparing both amps. *that's assuming both amps are 50% efficient. if you start comparing class A/B amps with class D amps - everything changes of course.
