How should I fix this air leak?

[Justinw303 10+ year member]

I have several small air leaks around the mounting ring of my box. It may be because I forgot to pre-drill so the holes aren't lined of exactly, or maybe the cutout is too big for the sub, but I can definitely feel a lot of air moving when the subs are playing, and it causes little rattles from the subs that I can hear when I flip the seat forward. It's mostly coming from around the screw holes, and when I put my fingers in a few of them to plug the leak, the rattling decreases, so I can tell that's the problem. Somebody told me this stuff might work.

I'm just confused as to how exactly to apply it, and how good it will work. I know I'm losing output and not getting 100% SQ, so I really want to fix this. I've been delaying it because its a tedius task and I don't have much spare time.

that stuff will help, but not if the whole itself is just too big. you can get that at home depot or lowes. its just foam weather stripping.

you should predrill, the wood has prob built up under the sub, which isn't letting it sit down flat and sealed.

Well, I don't really think the hole is too big. I'm pretty sure I just drilled the holes lopsided. Should I put the striping on, mount the sub and test, then if it still leaks, should I reposition the subs and re-drill?
