Installed a new head unit (Kenwood Excelon KDC-x705), JBL-62c 6.75" component speakers into the front doors w/ external crossovers under the dash, and a single SSA XCON 12" subwoofer in a ported Khaotik Enclosure (tuned to 32hz) today. I put all the wires properly through the door jams (what a pain in the ass, like everything is), but still need to double-tape the passovers better, and put some bracing in the rear so the box doesn't bump into my fuel surge tank. I did keep all the wires well away from the tank, not trying to start a fire! I'll take some pics tomorrow.
