i run kicker subs in all my vehicles, the L7 12" subs can go in two types of boxes, sealed or ported, ported hits much much harder, but sealed is a cleaner tighter sound, in my opinion. i have never seen a " truck box " for an L7 but thats not to say they dont exist or cant be made.
according to kickers specs on there website the 12" L7 in a sealed box requires a minimum of .88 cubic feet, so a little uner 1 cubic foot sealed, you should be able to get your local audio shop to build that for you for no more that $75 carpeted, at least in my area and they should be able to build it to fit behind your seat as well. i have a local box builder that could build one for you if need be and he is a great box bilder, get a hold of me if you want me to get you price and info, but keep in mind shipping will probably be about $40 due to weight of it
good luck
