This is my box,

38 long

20 wide

21 tall

Does it need bracing?

[farriswheel 0]

since you resined it, you might not need it. but it's not to hard to cut a cross brace and glue it in. just to be safe i would.

what sub is going in it?

Resin adds very little structural strength, unless you add mat along with it.

There's a tradeoff with bracing - you can make a very well braced enclosure with internal dividers, but you'll likely lose on a sensor with it.
