Throw a set of Dynaudio 6.5" components in your door and a set of 6x9's in the rear deck for fill, powered by a decent amp (don't need to break the bank, JL makes some fabulous amps that aren't expensive) and I guarantee you'll enjoy the music in your car again. Add a 10" JL sub in the trunk and you'll have an incredibly cool listening experience. You'll also be $4k lighter if you get it installed well...
