I built a temporary sealed box for my SSD, but I didn't have a router around so I ended up using a jigsaw to cut the circle for the sub. I also flush mounted it. Its sealed up except for one spot where I had a WTF moment on the jigsaw. Any tips on sealing it up? I was thinking about caulking it up around the entire hole (thats what she said) but thought maybe theres an alternative.
