Total ampage allowed by the fuses. Example a amp with 2x20 amp fuses is a 40amp amplifier and will give a maximum output of about 480 watts rms.

I'm no amp expert, but this sounds like complete hogwash to me.

Fuses are meant to prevent a fire if the power wires get accidentally grounded. So although the fuses must be above the maximum current draw of the amplifier, I don't think that translates directly into the amount of sound output you get at the speakers. Those fuses could be almost any value above the max current draw.

Can anyone who actually is an amp expert definitively confirm or deny the "fuse rating indicates amp performance" theory?
