2 12's
 

i have a 1998 extended cab and i was wondering if anyone could make me a box, or give me plans that fits 2 12's. also what are the best 12's that hit the hardest and sound the best.

I want to do the same in my '97 extended cab. If you find any plans please send them my way and i'll do tha same.

Well boys, you probably won't like my idea but I don't think it's possible to put 2 12's under the seat. Me and my buddy made this box out of 3/4" Medium Density Fiberboard like the custom shops. The box is 16"h x 16"d x 32"w. It could definitely be shallower though. The pics are here- Sorry, I don't have pics upof my 2 Kicker Comp VR subs yet. I would definitely recommend the Kickers, though. With 2 12 Kicker L7 Solobarics (the really expensive square ones) and a Kicker 1000watt amp, you wont even be able to stay in your truck. I am very happy with my Comp VRs. I just folded down the seat and attached to box to the flat area with some velcro which worked really well. Let me know if you have any other questions.

I will have some better pics up with the subs installed. Let me know if you want me to explain anything.
