We just finished two custom 12" boxes for my 04 WJ. I will post pics as soon as I get them from my buddies camera. I think you will like. I have seen another guy who did 2 10" JL's on the drivers side that looked pretty clean. I will see if I can figure out who it was. He has a pic or two on here with it. Also, if you want one 10", JL audio makes a prefab box for the drivers side rear that should sound pretty good. Expensive but so are all the materials for a do it yourself'r. My two boxes cost me quite a bit just for the resin, wood, carpet, burlap, truckbox liner, ect...
