if you are brave, and can carve out some depth, look at Exodus EX Anarchy . these things are monsters, and will be a great midbass/midrange.

and then a set of these, and forget the tweeter.

and seal off the access holes in the doors with something solid before you throw a layer of d-mat on them
the build in my satty will use the same idea(augmented widebander, as opposed to mid/tweet)
ill be using different drivers though, just picked up a set of H-audio ARduos....kinna expensive though
dont be afraid to do a little research. partsexpress.com, and madisound.com are your friends. i have built a front stage with a set of $10 ea peerless mids(it was a blowout price), and $34 a pair of vifa tweets that will out-perform name-brand component sets at many times the cost.
i have gotten back into audio in a big way lately, im sitting on a collection of 30odd amps, a few head units(including a couple of full-active units), and more speakers thn i will ever use.
i have been neglecting my time here a bit because of it.
