how much power? that's a big question most of the time, what with amps being under-rated, not accurate, so one, so forth. if you go buy a "500" watt amp, how do you know what it's actually pushing? well, it would be nice if someone in the know would key us all in!

example
my alpine mrp-m450 says that it produces 220watts x 1 under a 4 ohm load. i would really like to know HOW exactly to calculate this, and if this rating is BS or a real-world number.
