as for fitment...the stock speakers are 5.25" and your door speakers are 6.5" so they wont fit. you have to buy these plastic rings to get them to fit.
as for sound quality, your mids will sound okay but since they are aftermarket speakers, they will sound even better with an aftermarket head unit but i guess your factory radio will be okay. if your going to wait for the factory radio to die......your probably going to wait for as long as you keep your car. just save up about......oh..300 bucks or so and get you a good head unit
oh and WELCOME TO THE BOARD
