Only one I know of is Glasswolf, he's taking a break right now working on his Charger. He used to compete in IASCA and won a lot of pro events, I think he plans to compete again once the Charger is finished, not sure though. He doesn't do SPL comps though.
Know what you mean....I mean, I try to back off when I don't know something, but some people think that just because they figured something out for a specific situation that this is their blanket answer for everything.
awe nothin really worth mentioning, it was probably some kid talkin big, but his posts were so bad to everyone that it finally got to the point where we(motoman22, hydro, glasswolf) got so mad at him,(i think his screen name was yomomaz or somethin) i just told him off, his posts were so vulgar that a moderator erased his posts. so now theres an old thread out there with me goin off for what seems to be no reason, haha. anyways just glad too see that people are still using this forum to help one another
IASCA is the International Auto Sound Challenge Association, you're competing based on SPL, SQ, and install. Creative (and proper) install gives the most points, then SQ, and then SPL. SPL comps are purely who can hit the highest db within their class, and contain SLAP comps, etc.
Oops, I'm a little late on this one, didn't post it in a while. Yeah, if I ever compete (or get the means, $$$, to do so) I'd like to compete in IASCA, to me it seems to be the most difficult to win, but that's just totally dependant of both the class you're in and what SPL comps you're comparing it to.
