Super Crew Sound sub box

Has anyone used the Super Crew Sound sub box that will fit 3 10" subs in a 2nd edition double cab? It looks like a nice box but the only concern I have is will the subs hit the back side of the rear seats when playing music with lots of base? Any input will be great.

 

really depends on the subs you go with but in mine yes my 2-10 inch regular subs occasionally hit the seat but not that often.. i will be doing 4 flat 10 inch subs in my truck behind the seat soon and let you know i am going with flat subs this time because the exursion on the subs are less than normal subs and hopefully wont hit the seats.. good luck
