It would be nice if someone could post the peak amperage usage of certain audio equipment at high volume as a comparison guide to know what amperage cicruits would be needed.

Such as AVR and the different subs.

There is a meter that you can attach to a wire at the circuit breaker box that will tell how many amps are going through the wire. I plan on getting one of these sometime, but maybe someone reading this already has one and some Axiom subs.
