hmm.. any tips for sealing up a box? seems pretty self-explanatory, but.. any hints, suggestions, things to watch out for..? from what i udnerstand you just place the silicone at the seams.. what kind of diameter should it have?

 

Just run a small bead in the seams, and go back with your finger to work it in. You'll find that in a box with such a goofy shape as a thirdgen box, 75% of it will require you to squirt it onto your finger and work it into place with your finger. There's no way to get a gun down in a lot of those tight spots. Hell, you've got to be a contortionist just to get your finger there. If you're like me, you'll wind up getting silicone all over the place, and eventually it'll wind up in the creases.

 

use somthing liquid whiloe putting the box together too, like liquid nail and wood glue, that way it covers small holes up. then go back with silicone and finish it off, inside and out.

 

For straight square boxes, I do just what Jim said, and then I fasten the back panel to the box. Then route the holes for the driver(s), and it is easy to reach through the holes to seal the last panel. For my box in the Camaro, I just sealed as I built.

 

I like applying a bead of wood glue (Liquid nails or Construction Adhesive, etc) on each joint before assembly. Once its assembled and nailed/screwed/stapled I then go back from the inside and use a gun when possible, but you have to just use your finger on most all of it.


One thing I thought of that would work pretty well would be to take your box to a place that does spray in bedliner. They usually get that liner 1/8" - 1/4" thick.....it will seal your box.

 

Also make sure you let the silicone completely dry before installing the subs, the fumes from the wet silicone can help the surrounds deteriorate much quicker.
