never owned any, but i know a guy with 1 12 and it banged pretty good. also, about a week ago, i was sittin in my friends car, and a guy with a ford explorer dorve buy, and he was vibrating everything in our car, and he had an audiopipe sticker, so im guessing he had audiopipe.
audiopipe is like a reliable audiobahn to me, gets loud for teh price but dosent have great SQ...but still a big step up from audiobum. my friend had 2 12's on 2 power acoustik amps runnin 1200 watts each to em, they shook teh hell outta his mustang
I'm not too impressed by them. The loudest Audiopipe setup I've even heard was 6 15"s powered by 4 MA 4400watt amps. Had something like 10 yellowtops and a computer to control everything. it pulled a 154dB on a TL meter.
