1200 watts = 100A is @ 100% efficiency.
class D amps are 80% efficient on average. that's a class AB amp, which is 50-60% efficient on average. we'll say 60% being a PWM power supply.

(600/12)*1.4 = 70A
35A or so @ 4 ohms

Has to be an "aftermarket" fuse then.

You'd need a 20 volt system to get 600 watts with merely 30 amps, and thats assuming 100% efficiency.

I know 30 amp fuses don't blow immediately upon receiving 31 amps, but I'd imagine 60 would get the job done in a hurry.

I guess I was very ill informed on the difference between an a600 and an a600.2 ... mine has a 60 amp fuse... 1200watts = 100 amps hence 600 = 60amps....

It does say A600 right on the cover. First picture enlarge it...

Right there.... upper left sorta...

I dunno. Its possible a 30 amp fuse was employed because the thing was being run at 4 ohms, but it does look a bit "squat" for an A600. I'd suggest asking for measurements, but the model # ought to be plainly visible on the cover. If he can screw up that, he could just as easily screw up the dimensions as well.

:p
