ive tried searching for sub boxes for a 03 supercrew, I cant find anything so you supercrew guys where the seat back folds down onto the seat bottom let me see pictures of what kind of boxes you. mainly pre fab ones and where did you buy them at. I don't wanna raise my seat for the fact I have a child seat thanks in advance.

 

I had one built from sound of audio dot com. Waited a month but its good

 

have a link I tried to google it and nothing and do you have pics?
