A low, flat box with ports and subs facing up would get you numbers. Perhaps 7 cubic feet NET, tuned @ 42hz. Or, a nice rear firing ported enclosure for music + OK numbers.

ok cool thatd work being low would keep it under back seat and window height which always helps from window shoppers too lol..although i do need it to be a little musical since the boss n kids would use the car also
thanks again
