this box im making for my ta is a PITA. having to make all sorts of corners and angles to utilize every inch of space in my well. coming along good so far, i've got the bottom half done, and im coming to where it angles and comes to the top of the box. how do i go about screwing in the angle? do i just countersink it further in on the outside of the box, so it doesnt poke out under the carpet, and put the screw in at the same angle as the wood?

pics would help a lot here

screws? Off the top of my head, line the trunk area w/saran wrap and glue that crap where it sits.

I'd agree with you, drill the screws flush with the top side of the wood. Let them bite the bottom piece of wood at an angle if you need. If screws into MDF, predrill and use a countersink bit. DeWalt, among others, make 'em in 1 piece bits.
