SSA DCON - 15" OR 10"

[Jcarp0331]

I'm starting a new SQ build in my Denali and i have the sub narrowed down. The question that i need help with is what size and the placement. My two options are : 15" sealed to 3 cubic feet behind the 3rd row and firing against the hatch or a 10" ported to 1.25 cubic feet and tuned to 32hz and mount it beween the second row captain chairs having it downfiring about 3" off the floor. I'm looking for good sq sound that you can feel but i'm not looking to be heard from blocks away.Previously had 2-12" icons that did that perfect but i need the 3rd row. i wanted to make sure either one 15" sealed would give me the sound im after behind the 3rd row or it the dcon would work downfiging and the placement between the seats would be good in a 10".
