Say that you amplifier draws around 400 amps DC, would you need 4/0 wire for pos. and neg. power cable??
And if your output was say 75 volts and 51 amps, then would you need at least 8 AWG speaker leads??
Now my true question is this, what do you think would happen if you ran 4 awg power cables and 16 awg speaker leads for this amplifier??
Do you think that your output on this amplifier would decrease??
Because as an electrician I know that wire ampacity ratings are highly under rated. But in a house that could lead to fires and the such. But what would that do to a car stereo????
I was just wondering??

The higher the guage, the higher the DC resistance of the wire. The more current you draw through the wire, the more voltage will be dropped across the wire. If you draw enough current, there will be enough voltage drop across the wire that there will not be enough voltage at the amplifier to run it within it's specs. So ya, it will definately limit the amplifiers ability.

Rrrrolla is correct. National Electric Code (NEC) rates wire based on how hot it can get. Voltage drop is irrelevant; if you lose 5V in a 480V system, you're not going to cry. 5V in a 12V system, however, is a different story.
