I have the XE king cab. Im looking to get a speaker box but we all know how small it is back there. Im thinking I can only fit 10" woofers becuse of the space. Anybody know of a company selling sub woofer boxes for the Titan? Any reccommendations for 10" woofers? If i really try, is there anyway I can get two 12's in the back? Thanks for your help guys. :lol:

I found this:
link to product (http://www.soundoffaudio.com/item.cfm/id/2166)
It says it fits crew or king cabs, and will accomodate 8", 10", or 12" subs. Personally I think its a bit pricey. If you can take good measurements and have some basic woodworking tools, you can build something similar yourself for about 1/4 of the cost. There are alot of how-tos out there and there is a really good one at Crutchfield.

I built my own boxes for my SE CC. The carpeting was the hardest part.

Check out my post on the JL Stealthbox thread on the interiors section. I just finished a kingcab sub box for 2 10" JL 10W3V2 subs. I don't have it carpeted yet or speakers yet but the box fits great!
