I have a 2016 Rogue SV with the "Divide and Hide" in the cargo area. When I remove the top panel, there is a lip that comes up from the cargo floor about 3 inches, right behind the back seat. I want to screw down a 1/2" blown PVC board with an after market amplifier attached. Problem is I cant seem to figure out what is directly below it, and I obviously do not want to penetrate the fuel tank or anything else if it is mounted underneath there. When I look under the car, I cannot see if there is anything directly up against it. I searched high and low and cannot seem to find any diagram of the under carriage. I spent a few hours searching the forums on here as well as the field service manuals, and I can't seem to locate it. Any suggestions on where I can find what is directly below that area? Any help would be appreciated!

It looks like it could be the rear seat track support, cover by the floor carpet. If it is that, it's a c-channel shaped support piece that is fastened to the floor and there is nothing between the top of that support and the floor. Here is a diagram of what I think it is. https://parts.universal-nissan.com/a/Ni ... 47A_1.html
