Guidelines for Measuring Audio Power Amplifier …
https://www.ti.com/lit/pdf/SLOA068A
for measuring standard data sheet information for audio power amplifiers (APAs) is presented for several key parameters. These are: • THD+N versus output power • THD+N versus frequency • Gain and phase versus frequency • Integrated noise • Signal-to-noise ratio • Crosstalk versus frequency • Power supply rejection ratio
Output Power of Audio Amplifier

For factors we will discuss later, many times, even if an amp is accurately rated, you will not be able to use the whole output of the amplifier. For a pretty close guestimate, it can be as simple as hooking a voltmeter to your speaker leads when you play your amplifier and using the formula voltage times voltage divided by impedance.

Measuring RMS power output from audio amplifier channel
https://electronics.stackexchange.com/questions/530579/measuring-rms-power-output-from-audio-amplifier-channel
I came across this youtube video that suggests that by measuring the resistance of the disconnected speaker, and AC voltage across speaker terminals (while outputting to speaker), you can calculate RMS power from the equation \$𝑃=\frac{𝑉^2}{𝑅}\$, but all the other articles and videos I found suggested using a clamp meter to measure current, plus a regular …
Oscilloscope for measuring audio amplifiers' output power ...
https://www.diyaudio.com/community/threads/oscilloscope-for-measuring-audio-amplifiers-output-power-and-square-wave-distortion.372639/
I would like to buy an Oscilloscope and use it simply for measuring audio amplifiers' output power and distortion using a square wave. As simple as that. I would like to get an accurate measurement, quickly in order to check amp's condition/power. I know that we need a square wave input source, an oscilloscope and a dummy load 4/8 ohms.

of the filter-free class-D APAs. DMM1 is used to measure VS at the APA power pin. The generator injects a small sine wave signal onto the power bus, and the audio analyzer measures this ac voltage at the APA power pin and at the k V SVR V OUT ac S = 20log PSRR V V OUT dc S = 20log ∆ ∆ output. Here the analyzer, an Audio Precision System–II,
