Man that looks nice! Let me know how it sounds. I got my JL Audio XD700/5 yesterday should be good for what I'm doing with one sub. I'm going to have to play with this sub thing and see what works. I was thinking of getting a (1) sub prefab and trimming it down to fit under the foldout floor. I know it will affect the cubic inch room of the woofer but i guess it depends on the woofer i get. Again, not trying to go boom crazy.
I see you have a black truck with 24's. I do as well on my sport. I'm awaiting the 2/4 drop kit for the 2014's to come out. All the companies told me yesterday that they are prepping rides for SEMA now but when they get back they will be back to R&D and testing setups.
Take care! thanks for the input on the subs...
