the first loud system i heard was in a golf.Ahhh never forget the first time.it was 1991 in elkin,nc.at an iasca show.he was ther just to piss the iasca people off.back then there was no bass race or spl winners at those shows,it was all about quality.anyways he had 4 crunch 15's runnin on 2 hifonics zues i beleive.but anyways,i got to sit in it for a minute and goodness i was in love with bass forever.lolcompared to the stuff on this forum,he was just an average joe.but back then,there werent many 140 db cars around N.C. So get the car and load it up with subs and fix the jeep later!lol good luck and hey,its only 600 bucks.
