My donut & mount were removed by PO so I'm not sure of the space remaining in there. My guess would be that there is only 1-2" between the cover & the spare which is much less than you would need for a sub.

BTW, the door panels are much easier to remove than the rear panels. The first time you do it takes 10-15 minutes but after that, you can have it off in 5. Rowhard has a how to with pix.
