walled off car owners ! need help with sub floor- updated/done

[uhoh_45]

i'm wanting info on how you built your false floor for under the wall and how you secured it to the vehicle?? .

I'm just wanting some ideas for future build and am stumped (been away from audioz to long )

i dont own a walled off car yet but i would imagine you build a frame for support(2x4's etc) bolt them to the floor in the car(chassis if you can swing it) and go from there. it also gives you something to secure the bottom sheet of MDF to so you dont run into any problems with gas tank and hitting things your not supposed to.

Built the box in the van. Used the 3rd row seat hold downs to bolt the box in place. Could have done more, but it isn't moving unless there is a catastrophe.

see i've built one before long long ago and just kinda slapped it together thought it was good enough and never really did much with it so now i'm looking to do proper way of doing it

i was thinking of welding in some 5/8" bolts to the floor pan back there and using threaded rod to hold wall down and then secure to back where cut out is with some all thread.. (i donno where im going with this)

i dont wanna make it permanent and want to be able to remove it later on down the road

this is what i have to work with

Well, here is 20000 words, haha

Not much to mine really, but if you've seen my build log, then you know i had to beat my wall in the last 4 to 5 inches of the way. That things not going anywhere.

now i like the look of that its simple looking on the outside haha

but whats the inside look like- just bunch 2x4s stacked or what

I made a 2x4 frame then drilled and bolted it through the floor n tightened it with a impact wrench. Then jus glued/screwed the mdf bottom sheet to the frame

Nope. The two pieces of board you see is it. But when i put the double layered box in and screwed it to the platform, its like being 3 layers thick on the bottom. Three 3/4 layers wont hardly give any!!

well this is what i came up with

some coupling bolts welded up to some angle iron with hole drilled into it

attached to seat belt bolt

drilled some holes in some flat bar and bent it up to fit the seat mount

2x4 screwed to it

glued down the mdf with 3/16" area routed out so the box is flush

and its bolted in for now while glue dries (the alt hread will be unscrewed and box will be put in and bolted down to vehicle as well)
