Since the kids are in bed, I could not turn it up very far as their rooms are right above my HT area.

Anyway, I turned my meter on the 2 Volts selection and attached the black (COM) clip to the negative wire, and the red (volt) clip to the positive wire terminals.

When playing a particular song, obviously the readings bounced around, but the highest I saw it jump was 1.60.

So would this be correct using your equation?

P=Vsquared/R
P=2.56/4
P=.64 watts

Thanks, Randy
