couldn't you use elbows effectively to give you the port area you need to go inside the enclosure? two 3" ports with a 90 degree elbow should give yoou the length you need..

 
Yes thats exactly it, thanks

dude, i forgot!! sorry bro....i am off tomorrow so i will be able to get you those plans....

do you need drawings or jsut dimensions??

yep, you can indeed use an elbow to get the needed length.

I got your PM on SSA. Looks like everything is under controll. Dimentiosn and all see maccurate, however in the trucks ive taken measurements for its about 8-10" i nthe fron (play in the seat) and it goes down to around 6" in the rear if you really cram the box. The one im working on right now i have slightly smaller so that a grille wont be needed. I would have done down firing but w0's are space hungry little bastards and when you have maybe 2.5cuft total to work with and your subs want 2.5 net, things get trickey.

also make sure you have the mouting depth clearance.
