Ok, so this weekend I plan on pulling out my box and putting the zcon's in. 2 12" 1 ohm z's goin in. Gettin the diehard platinum marine sat nite and puttin the saz2500 in. Rt now my box is 4.75^3. Its an angled box to fit behind the seats of my 3 door s-10. I have another 4" of room I can go up. That would be about another 1.4 cubic feet or so. Rt now the port is on the side and has about 78 inches of area. 19.5 wide by 4 tall. Is that enough or should I make it bigger while I have it out? Or should I leave it alone? Also what would be a good gauge of wire to run for the subs? I cannot wait to hear these z's rumble!!!!¡¡¡¡¡

Port tuning frequency plays a part in port area. What frequency are you tuning and don't forget changing the volume will change tuning as well.
