Anyone upgrade their interior and exterior speakers?

i upgraded our 4 interior speakers from 4 inch single cone to 6.5 inch 3 way's made by Scosche. not high end by any means but they sound a million times better and mounting depth was perfect. i painted the removable grills white to match my cieling and they look great also. got the 4 speakers at walmart for $60 plus tax. im also upgrading the stereo/CD player to a car stereo/cd/dvd unit with an LCD screen and bluetooth. im also going to install a 100w x4 channel amp along with two 32 inch LCD TV's connected to the new head unit and a new HDTV antenna..

here are the speakers
