For anyone interested in more reading on how much power do you need here are a couple of interesting articles.

Both authors recommend amps much higher than the power rating of the speakers to eliminate the likelihood of clipping during peaks. One thing I've noticed is that everyone likes to raise the volume on their equipment every once in a while. Me too, as long as I don't hear distortion.
