Well I told him I would host the videos for him so here it is:

http://www.extremedigitalaudio.com/demo/

Now because I have been working with him for a couple weeks I can tell you his speakers are real and they are working. The system has the potiential to be great but still needs some work. Box design is all wrong the subwoofers require 3 cubic feet per 12" and he has two so it needs to be a 6 cubic feet box ported or a 3 cubic feet box sealed. I don't think he knows what loud really is just yet.

Amps wise I don't agree that crossfire is the best amp for the subwoofers, they can handle 3000 watts 1500 RMS. I am trying to tell him to pair them up with some MaAudio amps, or even an orion amp. Those subwoofers are pretty badass, the guy that does competitionw ith them had another guy with L7's look at those subs and just dropped out of the competition.
