Just wondering if any of you know what it takes to make a fiberglass enclosure for 2- 12"JL W6's in the midgate of my EXT. I'm looking for step by step information. I want to play around and try to see If I can build something for my truck. Pictures would be great. Thanks in adavance.

you will prolly have better luck going threw cardomain and look to see other peoples custom work to get a better working idea on how to do yours. I would say look at all trucks with rear looking like yours. The more pics you look for the better the design idea you should have. G'luck
