I built a small audio power amp to drive my computer
speakers. With one channel driven into 8 ohms the PP
voltage measured at 1khz was 24v before clipping.
With both channels driven it was 20v.

Peak-to-peak voltage has no meaning when computing power. There is no
such thing as peak-to-peak power.

You can use either the peak voltage or RMS voltage, and in either case
the formula is E(squared)/R. Your answer will be either peak power or
RMS power.

Since everyone is being a little picky, there is also no such thing as
RMS power. When you use RMS voltage you get average power. :)
