JL Audio StealthBox leaking air? 3rd gen Tacoma

anyone else have a problem with the JL Audio Stealthbox leaking air? If so, what did you do to seal it up?

i originally noticed it around the seal of the sub, but once i got that taken care of, i noticed it leaking some air around the bottom in the fiberglass wall. I attempted to seal it internally with some silicone, but its still not air tight.

Im tempted to pour some "flex seal" in it and slosh it around to seal it up.

 

I sealed my fiberglass subwoofer box with bondo hair and fiberglass resin.

To find the leaks, I put some water in the box, then moved it around till I found where its leaking.
After you find all the leaks, mark them, then sand the inside where you put the marks. Mix up some bondo hair and spread it over the leaking area. When I was all done with that, I mixed up a bunch of fiberglass resin, dumped it into the box and just moved the box around so the resin coated the whole inside with a thin layer.

 

yeah, probably should have done that before i put silicone inside it.

 

You can pull the silicone off, or just cut it flat with a razor then sand the area with 40 grit.
