Anyone drive one and still have the rear seats in. I need someone to measure for me that max size a box could be to fit under there. Im looking to build something like this for my buddy thats in iraq and his truck is in storage and i cant measure it. I would like to buy a set of plans for an an enclosure to fit under there for the 12" something similiar to whats in this pic. But maybe downfiring?



Its gonna be for a fully loaded 12" BL from FI

I went the other route, I took off the center fold down seat in the front and built a box to fit there :) too much hassle trying to fit 2 12's under seat without lifting the seat. Im gonna make an amp rack under the rear seats. Im gonna wrap it in black vinyl and my new black tahoe leather captain's chairs are on the way :D

you can squeeze around 2-2.25 cubes out of it sealed, not sure about ported. that's WITHOUT lifting the seat.
