Well its been a while since i talked my friend into trying one of these, and today we finally got the ***** installed. Did 2.4 @ 30Hz, with subwoofer tools. Nothing fancy just thrown in there with an http://www.crutchfield.com/S-VHrLvQ3JDTN/cgi-bin/ProdView.asp?g=120&I=500MRPM650&search=alipine+amp. All I can say is wow. It is as accurate if not more so than my Type-X. Ran through some songs, first David Matthews "Where are you going". Every note was right where it should be and clear as a bell. Its really "fast" as well, it moves like would you would expect from a 8". I was a little worried that the output would be really lacking with it peaking at 500w, so i threw some ludicris on. Its hits hard and clean (for what it is) youre not going to win any SPL comps with it or anything but the overall feel is fantastic. This is not really a review as i dont know as much about whats whats as a should but if you get a chance check one out for sure.
