Any ideas on a box for 4 12's on a extended cab.

you will have to build a big ass box, if you go with ported box it'll be even bigger, from what i remember, 4 12''s will not fit all in a line you will have to stagger them,

i ended up going with 4 10''s back in the day, and still took up alot of room

4 12s can be done. Best was to do it is build the box 52-54 wide and they will fit in a row.and do the port on the top of the box. Its a tight fit though

yea its going to be a chalenged. Do you'll have any pics of sum
