In order to measure the output of an amp, you would need test equipment;

Load resistors, scope & some type of audio generator. Here's a good example for car audio which is valid on any audio system.

Like I mentioned, It is the same for ANY Amp. Basic fundamentals are the same.---only difference is in the supply voltage of the circuit.
