looks pretty good. there sure isn't much room back there with the extra seat lol.

i'd like to see some with it a little more finished

Man If I had the room i would of built the box..... well I wont tease my self....lol With 3 kids i needed the 3rd row seat and with such a nice truck there was no way i wasn't going to put a system in it. It took alot of measuring to get the box as big as i could and still use the 3rd seat and be able to access the jack/tool compartment.

which box are you using? 1 or 2? if its #2 then you could have sloped the back a little so it would be flush with the seats to get some more displacement, and no independant chambers!? The other box looks good, sure will be a heavy ******* once the subs are in it I bet. I like the down firing idea, but does it down fire right into the jack tool compartment, I would think that would just be asking for rattles with the tools and flimsy cover? let us know how it sounds when complete!

The box with the shared chamber was going to be the initial box but i had no where to mount the sub amp and didn't have the clearance for the subs to fire into the tail gate. The total internal volume was 1.45cu ft.
For the down fire box I made a bottom so the subs are firing into 3/4 mdf. The box is screwed into the panel for the jack compartment so if I need to ever access the compartment I just put the 3rd seat down and unlatch the panel then tilt the box over.

It's been in for a few months now and let me tell u,.......... I have been asked many times how i managed to squeeze 15 ('s) in there.....lol

For those that dont know what subs i have click on the link .
