    Normally you could read the specs on your speakers, or check their website for technical specifications or consumer help.

    Electronic techs use expensive test equipment, like a True RMS AC Power Line Analyzer, for accurate measurements.
    You could try hooking a voltmeter to your speaker leads when you play your amplifier.
    Using the formula, (V^2)/R voltage times voltage divided by impedance. Be careful you don't explode each satellite & blow a hole in the floor!

    Wattage, the power a system draws, can be measured three ways:
    * RMS (Root-Mean Squared)
    * RMS Maximum - The maximum power a system can reliably handle in bursts.
    * PMPO - the maximum output, Peak Maximum Power Output

    How about an ammeter to measure the current?

    Impedance = V/I
