30 amps x 12 volts x 70% efficiency (that's being extremely generous on that amp if it's not a class D) = 252 watts per amp (not per side, but per amp)
no denying those numbers. There's no way you're getting 500 watts out of those amps, I even doubt that you would get 500 watts on a short burst.
and 100A fusing?
absolutely not doing a damn bit of good other than protecting the wire...but even then, it's not doing much good protecting a 4 gauge wire, you'd need around 2 gauge for a 100 amp fuse to be protecting the wire when we're talking about lengths in a car.
30 amps x 2 amplifiers = 60 amps of fusing. You shouldn't have much more than 60 amps of fusing on that power line. (again, that's if you're running 2 of those amplifiers)
By running a 100A fuse, you aren't protecting anything. HOWEVER, kudos on at least fusing the power wire!
and scott, you're right, I'm just rather annoyed at newbies that seriously think their **** is right yet when you crunch the numbers, it doesn't even come close to what they are claiming. I'm just tired of running into it over and over again. I know it's not this guys fault, I just wish more people would do a bit of research before purchasing things. Lost of money being blown down the drain.
