there are really lotta good stuff now in the market, JL, RF, CerwinVega, JBL, Kicker, DD, MTX, etc. just to name a few...
you see, everytime a brand makes a good mark on a SPL or SQ competition, i (or i think everyone if im not mistaken) wants to get a system or even just a pair of subs that just won a competition.
hehehe, this is a funny thing coz when i started to get involved in car audio, its the cerwin vega's reign, when i first got my car.. its kicker, JL etc etc. now im working... all this JL w7s, JBL Gti, etc. come up! i dunno which one to choose.. (even though they dont sell much american products for car audio here in australia, and thats plain bullsh*t)
