is there a DIY on taking the back seats and brace out? ive been searching for about an hour now and cants find it.... im building a big box for 2 12's and im going to have to go through the back seat opening to get the box in there... any help?

Pull up on front of seat bottom,

Remove.

Undo two bolts on each seatback (14mm if I recall) lift up,

Remove.

Under no circumstances take the steel crossbrace out,

Done.
