Sub boxes for 2001 double cab

Hey guys, just wondering what sub boxes there are for 2001 double cabs, preferabley behind the rear seat kind. For double 8"s or double 10"s. Thanks

 

Damn... I have a hard time keeping my cleaning supplies behind my rear seats! I will be interested in what you discover.

 

Seen this in a 2003 double cab.

havent had good experiences with the sub-amp combo units like that one. ps they sound like crap

 

I put a Kenwood KDC x792 deck and kept the stock speakers in my truck a couple of weeks ago and it sounded allright (IPOD hookup). Then I added a Kenwood KSC SW1 pwr-sub ($80.00-Ebay) and now Im totally impressed. I dont have much experience with the boom systems but Im a happy camper. For a total of about $300.00, I cant complain.
