well im real short and i have porche 924 seats and right now i have an mtx sealed between my seats. i was thinkin that i could make a box that takes up the whole back with it in the middle. and in the middle build it out because the sub is like 7 3/4" deep. its a monster. then have a port on the top in the middle or something. anyways heres a pic of my seats. and thanks for the replys. -bf
