I recently sent a letter to an ebay seller questioning an amplifier that had an unbalanced watts/fuse ratio. Here is the letter and the reply..
this amplifier (1400w stretch daddy 4ch soundstorm amp), how many
30amp fuses does it have? by my calculations it would need 3 30
amp fuses to reach 1400watts, and that's at 15.5 volts. If it only
has one, 46.6v is necessary to reach the 1400w without blowing the
fuse. I am not trying to be an a$$, I am well aware that car
amplifier companies overrate their products, not the seller.
Hello,
This amp is rated at 150W x 4 channels RMS power at 4 Ohms. This
works out to an output voltage of 24.49 V/4channels. This causes a
draw of 6.12 A/channel making for a current draw of 24.5Amps total
to drive the amp at it's RMS rating. Hense the single 30A fuse.
I can't speak to how the max ratings are determined, but I would
bet it causes the fuse to blow a very few seconds after obtaining
it.

So if the amp is tested and rated at 24v, it should run at 24v right? So my question is, how difficult is it to run a higher voltage system? I know the basic theory, but has anyone tried it or know exactly how it is done?
I was thinking of wiring 2 batteries in series giving a 24v output, but would a regular (secondary) car alternator charge this at 12v? or would a 24v alt be needed?
-just curious
