wuw, how do you measure just from the negative or just from the positive? Put one of the voltmeters thingys on the positive terminal and then ground the other one??? or wut???

Dukk

You measure at the speaker terminal, not the power terminal.

Handy to have 2 meters: set one for AC voltage and measure the voltage across the speaker output terminals. Then use the clamp on AC Ammeter to measure the current in the speaker wire at the same time. Multiply the two and you have wattage.

Incidentally you could then set the meters for DC and measure the voltage and current at the power terminals and then calculate amp efficiency.
