I'm building a new sub box for my car and am wondering how much it affects the SQ to have leaks. I've made the parts fit fairly well and used lots of glue in the butt joints with nails to secure. Each joint is clamped for an hour to set and i run a little extra bead of glue along each joint to help improve the seal. So how much leaking is acceptable? Does it really even matter that much for a sealed box rather than a ported? Should I get some sort of caulking to further seal the joints?
