Mounting sub in pre-fab box

Ok, so I bought a sub and pre-fab box from Sonix. The box is carpeted and the sub overlaps the carpet a little bit. Should I cut around the sub when it's in place so it's directly on the wood? I'm using 1/4" T-nuts in 6 places and 2 wood screws in 2 places that are too tight to fit a T-nut in. The Sonix video for this sucks. They say use T-nuts but then use screws.

the carpet actually will work as a seal. It's a good thing. I've also only used screws for my boxes.

most boxes are made out of fiberboard. they don't take screws well and Tnuts don't hold well either.. What I often do is make small blocks of ply wood and glue them under the edge where the screws or Tnuts will go... no splitting!

and yes. rest the sub on the carpet.. good seal!

Thank you both for your input. I did manage to get 6 1/4" x 20 T-nuts in with allen head bolts. I had to use 2 1x5/8" wood screws because there wasn't enough clearance with the inset wall of this box to get a T-nut in. I left the carpet and it's sealed up nice and tight.
