500 watts?

not sure, but i think the 2290 is only a 90 watt device right?

in my car, i have seen 350 to 400 watts out of the amp.

that equals about 57 amps by your equation, and im sure you are right about the power supply being 40 amps constant.

good call, that is probably it.

i think i forgot that AB biased amps such as this draw more current for the same output as a class C amp would.

thanks for the advice, now i know where to start to fix it.
