[QUOTE="CHEMMINS, post: 7197033, member: 625734"] Current = Amps. So therefore....in a perfect world, an amp that is 100% efficient, a 120a fused amp with a alternator voltage of 14.4 would yield 1728 watts at full tilt. In reality..... Amps are 75% efficient. So at that rate.....even if the full 120 amps is being sent through the fuse (which it isn't) you get 1296 watts. Give or take voltage floating.....say a sustainable 13.8 volts. You would get 1242 watts full tilt. You are gonna play your amps at most 3/4 volume to avoid clipping. So that would be - 931.5 watts Average listening volume on your deck will be 50% so in reality you will actually hear 465.75 watts. [/QUOTE]
