Quote:
I = amperes
Po=RMS
n=efficiency
V=voltage

So for me its:

I = (3000 - .8*3000 + 3000) / 13.8
I donno about your car but most vehicals these days run at about 14-16 volts at ideal.

But if you are pulling 3000 watts rms that looks like a fitting amount of amps. I dont know what amp you have to tell you how things are running. IE how many watts RMS you are pulling at what ohms it's set to.
