Gah I hate all of you guys. Because of my stupid second occupation (bowling tournaments for $$$), I have to have enough room for four balls in my trunk. Sort of limited my bass potential.
Anyway, I have the factory JBL upgrade to start. Then added a Rockford 700S amp, and two 10" HE2 subs with a 1 farad capacitor. Sounds clean and bumps some, but I wish I had room for 12"s or bigger
