I am wondering if the 08 quad cab rear seating is the same on my 09 crew cab. i am looking for sub enclosures and i was reading that they might be the same. Lookin to put 2 JL w3v3's in the back.

 

I think they are the same. I installed the fold-flat rear floor in my crew cab that is only available from the factory in a quad. Check out these two threads for pictures and judge for yourself. https://dodgeforum.com/forum/4th-gen...ear-floor.html

I have not bought one yet, but I have contacted both husky and DUHA about underseat storage bins, both of which have said that they've tested and both bins are the same, which would indicate that the area underneath is exactly the same. I can't verify this myself though.
