custom Sub box for Baja

[Jungle_44]

I built a variation of the sub box already posted.




First I used the dimensions from this thread :

(I used caulk to seal up all the seams while constructing it, it's too skinny to caulk after it's built.)

Then I eliminated the rear portion that sticks thru the bed opening.

once I had the small "truck box", I mocked it up, and threw it behind the seat.

with everything in place, I traced the opening of the bed pass-thru.

Then I ran a peice of 1"3/4 tape on that line, and traced it.

This moved the hole to be cut, inward about 2".

I used a gigsaw, and cut this panel out. Then put it on stilts about 4" out from the back of the box.


I draped the enclosure in fleece (sweatshirt material will also work), and stapled to the original line I traced of the rear access pass-thru.

Then I stapled it to the sides of the box, too.

Then came the stinky, itchy stuff.

I slathered the thing with 2 quarts of liqud fiberglass resin, and after 20 minutes it was hard and ready to sand.

I buzzed it all down with 80 grit on a DA, then slathered it again with 1 qt.

Buzzed it again with 80 grit on a DA, then smeared the whole thing with body filler to smooth it.

Sanded, filled, and sanded again. Finised with 180, primed, sanded with 320, and painted it.

The next day, with dry paint, I added some strips of threshhold that I painted black. I got them from Home Depot, and cut to size.

This added a bit of protection and ruggedness because it is in the bed of a truck after all.

Oh, I also sunk the speaker in flush against the front of the box. Do this while building the box, not after it's done!

I covered the box in charcoal felt, and added some furniture footings to push against the rear seat and keep the box tight against the weatherstrip of the bed.

I installed radio shack binding post terminals on both sides, and stuffed a good size chunk of pink fiberglass insulation inside, on both sides of the enclosure.

Then I hooked up my 10" Dual Voice Coil Sony Xplod speaker.

Interior cubic dimensions are just under 1 cubic foot, 0.9. Perfect for a 10"!




box can fold down if needed, and can come out in a matter of seconds.
