had a comp setup for a few years but never really competed.
CDT audio component sets front and rear, pushing 125w per channel up front with a jbl amp (forget the #'s) and the rears running off of a crossfire amp pushing 50w per@4ohms
Pioneer head unit
Single DDaudio 10" subwoofer in custom 1.5cuft ported box with 24sqin of port area 12" long. Tuning could be adjusted by cutting port area in half for spl or SQ. Close it off and got a real tight POP with good boom and open it up for just the opposite. The DD sub was so clean tho, the difference was only 2db... It was running on another jbl amp with 450w going to a 300wrms sub.
Best score was a 135.6db
but it was all about sound quality ;)
