Sufficient for holding carpet on, probably. Gluing the box together, no. To glue the box together use wood glue.
I figure that, barring any room correction which would require a cut, I can set boost eq to 22hz at like +3db and .5 Q to get a little more and it should sound pretty good, right?
I'm possible to say. right now.
What kind of paint do I use for PVC ports?
I would suggest using flared Precision Ports that are already black.
Using DAP Fast Dry Acrylic Latex Caulk Plus Silicon for joint sealers is that good or would going with hot glue be better?
I would probably recommend caulk / silicon over hot glue.
Wood putty for screw holes, correct?
If you're carpeting the box, it doesn't matter unless they're visible under the carpet.
Do I need to sand at all if I'm just going to use carpet on the outside?
The spray adhesive might stick better if the outside surface is a little rough, but it might not be necessary. You could test using some scraps of the carpet and wood.
Can I use MDF to brace joints or is solid wood recommended?
MDF is fine for bracing.
Can I get away with just one crossbeam? If so, which direction? From side to side?
Hard to say since it's not clear what you mean by crossbeam. What are the dimension of your planned box?
What should be the order of my steps?
Something like Cut, glue, screw, wait, seal, wait, assemble, test, disassemble, carpet, final assembly
Does flush mount make an audible difference from face mounted?
For a sub, it doesn't matter.
Should I glue in between each piece or just seal the box after I screw it together?
You should glue in between each piece. The glue is largely what end up holding the box together. The screws largely hold things in place while the glue dries.
When do I put the carpet on, before or after the box is put together, etc?
I don't want to, like, put the box together and glue it only to find I need to brace all the joints...
bracing isn't to reinforce the joints. It's to reduce panel resonances. The joints don't need bracing the large unsupported open spaces in the middle of the panels do.
