Looks like its coming out pretty nicely. Nothing wrong with spending money I guess as long as ya got it. When your done with the install wanna ship some of them tools my way lol, porter cable makes some pretty nice stuff.
While your at it where's the supercharger and exhaust and lift and other good for a 4x4 lol.
Gonna need some good highs/mids to keep up with 2 fully loaded BTL's but your definitely going overboard, 2 sets up front well placed I think would look better and sound just as good, maybe run 2 sets of what you got with some 8" mid bass that would be pretty sweet.
