Punch is not so great, Power series is. This amp will be fine - because, while I might not recommend their speakers based on sound quality, I'd have their amps on my recommended list based on their "bullet-proofedness". I also think 65 x 4 is plenty. Yes, a more powerful amp is even nicer, but unless you're planning on waking the neighborhood, 65 will be quite a bit. RF amps are also typically under-rated. For most people, 65W per channel is "enough". If you're just looking for a good, reasonably priced setup, again (my opinion is that) this amp is fine.

I use RF Power series amps in my car, the fronts at 100W and the rears at 62.5 (strange rating, but that's what it is). I like my music loud, and my ears give out (can't listen for more than a few seconds at top volume) before the speakers do (Boston Acoustics Pro series), and the speakers give out before the amps do. Basically, 100W front and 65 rear is more than enough for me, and again - I like it loud.
