I have a 2000 Nitro NX882 and driver and passenger seats both have storage compartments under them, but the center seat seems to be fixed in place. I have un-screwed anything yet, but was wondering if anyone else had, and might know what is under there. The storage compartments of the other seats are walled on all sides, and behind the center seat is the live well. I cant imagine it's solid material under it, but it doesn't seem to have any easy access. Anyone ever investigated to see what might be under there?
