First one is a pos it's made out of particle board it'll fall apart.
To be honest after over two years its still doing fine, sounds great and I can still ride people in the back.

Hey 92GreenYJ,
That is a nice setup you've built! It looksmuch nicer than some of the specialty plastic formed boxes I've seen on crutchfield and elsewhere.
I'm wondering if by any chance you would happen to have (and be willing to share)the plans for the box you built. I was planning on doing something similar, and if you have rough numbers for thebox sizeit sure would save me a lot of time.![Big Grin](https://dodgeforum.com/forum/images/smilies/biggrin.gif)
Also - I'm curious as to which thickness of MDF did you use?
For the"seat lift kit", what did you end up doing? Just use some blocks to raise it up on the back, and let thefront rest on the box?
Any help would be very much appreciated.
Thanks!
Cartman

ya im extremely curious how you got your seat to lift up a few inches. Also is that a sealed or ported box setup? Do you think i could do the same thing but on the driver side only as a sealed box? Thats definately a neat setup you have there, any info on your DIY would be great.

Eric,
first i haven't solved the bottom seat brackets yet. for the brackets on the seat back I just welded on some extensions.

for the bottom im just gonna fab up some spacers to bolt the seat down to. just haven't had time to get over to IMS for the steel yet.
As for measurements, not sure they'll be much help as i had to make more than a few changes and modifications when I went to install it. I built the front, top, and back panel first. mocked it in and then built the sides and shaped the bottom from there. The bottom is probably about 20 different pieces of wood nailed in at odd angles and then I filled all the gaps with bondo fiberglass resin and sanded it smooth. then i had to add risers for the subs to the top so the magnets would clear the bottom of the box. If you really want my starting measurements i can post em here in a bit, gotta go out to the garage and find my notebook. as for materials used. I used 1/2" MDF some 1/4" lexan, (windows) nails for my pneumatic nail gun in various lengths and enough silicone to supply the playboy mansion. and of course two cans of bondo.
terra, its sealed. around 1.3 cu ft of airspace per chamber near as i can figure. and im sure you could work out a smaller box to just fit one side. just halve my measurements when i post em

alright works for me, such a difficult vehicle to get subs in while still keeping the backseat open for seating. measurments are always appreciated, but i have actually thought about making my own stealth box. I found a DIY to do it on caraudio.com to replace the middle seat witha box while still keeping the middle seat useable.

ok so here are the measurements i started with. i actually have two numbers for some of these as i kinda went thru a smallest box i can make biggest box i could make kind of thing. I went with the larger numbers.
Floor to bottom of seat (front): 7"s max (all the way forward like i did) 9.5"s
length (between the seat brackets from the floor) 54"s
Width (front of seat back to the hump on the floor pan) 16"s
floor to seat back (at the back) 3.5"s this i ended up cutting down by 1.5"s to 2"s
for the heck of it i have all the airspace calculations i did too so i'll post that stuff. remember this is airspace for one big box, not accounting internal bracing etc. i have airspace numbers for both 1/2" MDF and 3/4" MDF for three different sets of dimensions. again i went thru the how big do i want this thing dilema.
L = length, FH = Front Height, RH = Rear Height, D = Depth
Smallest box:
Measurements: 54"L x 7" FH x 3.5" RH x 16" D
1/2" MDF - 1.95 cu ft
3/4" MDF - 1.65 cu ft
Medium Box:
Measurements: 54" L x 9.5" FH x 3.5" RH x 20" D
1/2" MDF - 3.2 cu ft
3/4" MDF - 2.81 cu ft
Large Box:
Measurements: 55"L x 9.5" FH x 3.5" RH x 20" D
1/2" MDF - 3.26 cu ft
3/4" MDF - 2.86 cu ft
the box i ended up with was the medium box. think i ended up at about 1.3 cu ft per chamber but i haven't tried calculating it with all the bracing and such as i suck at math. hopefully this will help someone. if anyone has any other questions about my system please feel free to ask and ask here or in my thread in mobile audio so others searching in the future may benefit from this as well.

I'm thinking about pulling out my rear seat entirely. I'm looking at installing my kicker comp vr 12 in the middle with a forward firing config. Basically building a bench where the rear seat is with a storage box behind the passangers seat and an area to house my amp, cap, and crossovers behind the drivers seat. I still haven't decided yet, not quite convinced that my rear seat needs to go.
