multimeter - Measuring RMS power output from audio ...
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 …
Peak vs RMS Meters - Biamp Cornerstone
https://support.biamp.com/General/Audio/Peak_vs_RMS_Meters
RMS ('Root Mean Square') voltage is a complicated-sounding engineering measure of the average voltage level of electrical signals. Because the RMS meter measures 'average' levels, a sustained sound reads much higher than a brief percussive one, even when both sounds have the same maximum voltage level: the reading is dependent on both the amplitude and the …
