I want to add 1 or 2 subs in my 2003 Super Cab. I am new to this and am wondering if I will have to raise that back seats or just use 8 inch subs. Where could I get a box or does someone here make them for sale. Thanks for the help guys.

 

im working on a seat lift and a custom box for 2 12 L7s right now. ill post some pics when im done

 

If you have captain chairs up front, you can stuff one 10 under the console,
you can find boxes on ebay that will hold usually up to 10's that slide under the back seats, with out a lift. Subs fire up into seats with that design.

Or do what i did, and think outside the box (no pun intended) and make up a custom set up.
