2014 and 2015 tundra crewmax box

[(SS)]

I own a 2015 tundra crewmax and plan on doing a full system in it. Of course the big issue is the box behind the rear seat.There is very limited space back there. It's looking like 7" at the bottom and 2" at the top. I've narrowed my choices of subs down to the jl audio 10tw3 or sundown sd-3. Both are shallow subs and would be really loud. Has anyone seen or done any box's for these trucks?

Anyone mess with one of these?

I've heard great things about both these subs, Sundown seems more SPL than sq..
