Figured I would get this started for him because I just finished up his sub box for the new GCON. So far we have installed a sony cd player and 4 Kicker 6.5's in the doors. The amps are picked out, but not purchased yet. He has been working hard to earn money to make these purchases, but as a good uncle I do not let him spend all of his money on audio equipment. Audio is fun, but gas and van maintenance are first. I snapped some pictures of the box as I was building it. Box is 22x21x18 which should be right around 3.64 cubes after sub displacment. We may have to add some polyfill to dampen, we will see at a later time.
