If you are retaining the rear interior pieces, you have 29” wide. The spare tire board goes all the way to the seats though. You could cut it and put a piano hinge a little further towards the rear, but my suggestion is just make the box as deep as you need for the subs you choose and just make it easily removable in the event you need to use the spare. The height of the box is a limiting factor as well, if you want to retain the hatch cover piece. You can fit 10 1/4” tall before hitting the metal bracing on it. I found that one good 10” with proper RMS power from an amp is plenty for big bass.
