or just an empty shallow sub woofer box and a kicker shallow sub

and what amp and stuff i would need to go with it. any help would be greatly appreciated. thanks

although their expensive, i would say that the new jl audio flat subs be better. they designed it realy good. ive heard it in a truck and it sounded as good as 2 w3.
