Amplifier power ratings are based on the *rms* value of a sine wave -
hence the misleading term "rms power".

Well that would make sense with RMS being, IIRC, equivalent to the DC
heating effect in a resistive load.


RMS is an amplitude, e.g. 'volts RMS'. Phil's right that the term is in
error, but there's so many lies and so much snake oil in the audio
business that this minor absurdity seems a fairly small price to pay to
clear away all the "peak intermittent music power" (PIMP) nonsense.
