2 18" BTL's, 1 rockford fosgate t4000, box a little over 12 cu. feet, rf mids + highs and amp to power them - have to shop for that still , new alt/batt. (any recommendations?) , high quality wires since I found out the difference they make on my home system,...new alarm....all in the back of my '96 grand cherokee. I'll do the build sometime this month. Also if you have a link to help with ported boxes since this will be my first one that will be nice, or tips....thanks guys, cant wait to hear it.
