Do they make an under seat or behind seat single sub crew cab box for a 12" sub? I have my 12" JL 12w04 from my old Sierra but the box won't fit, and I was told by a local sterreo shop that they only make a 10" box for the crew cabs. Is this true?

Dont know about 12's but here is a place to start:

LATER!

Another place you might want to try is

http://www.subthump.com I looked here for a box when I was doing the system in my truck. If im correct they make an under the seat box and a behind the seat one also. I know with the under seat box it has a true 6" mounting depth with an added 1/2' spacer, its a sealed box and fires downward.....the only problem is that the seat backs do not fold down flat....if you go with a behind the seat box your kind of limited to what subs you can run because of the depth......

I went with this box here http://www.streetracr67.photosite.com/Subs/ the quality of this thing is amazing. It holds 2 peerless 10's ( 2ohm) and hits pretty hard with all types of music...the price of it is def not cheap but you are getting what you pay for..............any questions feel free to send me a pm

try having one custom made. I had a box made for my f350 and was cheaper than a ready made one .:grd:

Ricky? Is that you? Lol

I have 2 10's in my 03 Crew Cab, try www.audioenhancers.com, i got the box for 250 they sound pretty good, there infinity subs, go to wall mart and put some pillow stuffing in the box, youll probably wanna take that plastic panel off that is above the box because it will rattle. I really dont think your going to be able to put 2 12's in that truck.
