I just need to now how to now the real power from the amplifier.
I now the are many ways to do it, but I not now wich one is the best, I here something about take the amps in the imput and then multiplicate by the output voltage and divide for the volts of the batteries like many many other ways.
I like to now if anybody has a better way to find this.

you need a true-RMS clamp ammeter and a GOOD voltmeter. measure the voltage during the test burp, and clamp the amperage a couple seconds into the burp. write down both numbers. also helpful to write down your frequency, volume setting, and spl from the termlab. multiply voltage times amperage. that's your true reactive wattage. volts divided by amps is true reactive impedance

And what I doo with the Amperage in the imput of power, and the voltage for output?? do I have to multiplicate, ??? ore what to get the RMS for only 1 amp??

measuring input power, amperes and voltage. That gives you the ability to compare power into the amp, versus power to the speakers. Output divided by input from batteries tells you the amplifier's efficiency at that voltage-power-frequency-load

So if I understand you right I have to divide the output voltage to the woofers by the Imput Amperage that the amp show me in the burp and thats it??' and what do I do with the imput Voltage ore only need the amperage???
