I think DOMINO is looking for aftermarket stereo equipment. In that case, go to the local car stereo shop with the best reputation in your area, and go from there. The center console will surely have to be modified somehow, but the possibilities are endless.
As far as the speakers, a 6.5 component set-up will go in the stock speaker location with a custum built bases, and a custom box for a sub can be made to replace the "subwoofer" in the passenger side footwell with a real subwoofer.
