Does anybody know the fuse rating on a ZX750.1? I know theres 2 fuses, how many amps are each? Ive looked around but cant seem to be able to find this.
try using it to explain an alpine pdx1.1000 with four 20A fuses, drawing around 90A of current, and putting out almost 1100w rms. pick up this months "performance/auto and sound" to check it out.
is there a more accurate forumula, because yea the zx750 would say around 700 watts with the fuse rating but fuses can handle alot more than what it says.
If an amp has 80% efficiency, it dosnt mean that it draws 120% of it's rated power.
1000 watts - 80% efficiency Would mean that it would be pulling the amperage to support 1,250 watts at 100% efficiency. So at 12 volts = 104 amps.
Using your formula - it would be 1,200 watts, or 100 amps even.
Not too much of a difference, but when you want to figure out exacts, etc.. (which is hard to do, because amps fluctuate in their efficiency anyways...)

That's about right.. 90 amps of current, x 14.4v = 1,296. So for 1,000 watts of output, and 90 amps of current drawn, it would show the amplifier is working at about 77-78% efficiency.
