so ive got a 2000 chev silverado ext cab and i measured the depth that i had under the rear seat..........and after looking at different website's i was thinking about buying 2 kicker L7 8" subs and running them under my rear seats powering them with my RF power T10001bd amp....any suggestions or opinions on how it will sound.

 

they actually work good for a 8"
but you might want to get 3 of them.you have a good amount of room in that thing.
