stereo system-help

I was wondering if anyone would be able to help me out.I would like to put some subs in my 2005 gmc crew cab but i dont really have alot of room. If anyone has any suggestions or pics i would really appreciate it. There is one truck on this site with a system like that but they havent been on in a long time. Ohh yeah i cant really lose any seating either. thanks everyone for any help

Well if you dont want to lose seating, i guess youre looking at your box(es) under the rear seat.......i think JL makes some specifically for those

there is plenty of room for two 10's behind the seat. just make sure the woofers aren't really deep. sounds way better than under the seat. I do it all the time.
