I have an Eclipse EA 3422 amp that i have on my Hi's! I wasnt into the type of stuff when I bought it so I dont know any specs on it. When I got my system almost 2 yrs ago, the deal at Tweeters told me it would push my JL componets and sound great. (they always tell you that) Well i was looking online at the Eclipse website and it said my amp has 490w max. Is there a way to determine the RMS?

first of all, great amplifier.
Eclipse actually does make very well-designed amps. They use stuff like dual toroidal transformers in the power supplies.. costs more, but better in the end.
You lucked out there.
