Which Car speakers seem better?

dude, if you want to change your speakers change all 4 of them, otherwise is not going to sound any good, Alpine S are okay speakers. For SQ you'd want something highter. 2 of my friend have uses the Alpine speakers, they are okay. but I am looking into infinity speakers now, since one of my rear door speaker is blown due to the competitions. I still think infinity speakers are good for the price and quality, also can be a competition set speakers.
