Hi DJ,

This is a good link to read about Power and how to measure it.
http://www.eatel.net/~amptech/elecdisc/2ltlpwr.htm

The whole site is very good to understand basic electronics.
Hours of fun guaranteed!

Basically, if you have a 'true RMS' meter you can apply a 1Khz sinewave and run the amp at full power just before clip.
Measure (in AC-mode) the RMS voltage and the RMS current.
RMS voltage * RMS current = Average RMS power.
There's no better way to explain things in a simple way.

Also perform a search on RMS, average power, ... on this site.
You will find a lot about the subject.

/Hugo ;)
