I've had this for about a year now. It has a 9 speaker infinity sound system that came stock with the car which I've been very happy with but their starting to go out so I'm looking to replace all the speakers except the tweeter in the dash. I think it'll be four 6.5 in speakers and 4 tweeters I'm not sure what size they are. I need some help getting a for sure size and suggestions on types of speakers. Thanks!
