I'm looking at component speakers, and i need some info if anyone has these speakers and know how they sound. The first is the alpine type R components. I have two alpine type r 12's in the back and they sound really good, so i was going to get all alpine in my car, because the subs sound great, but i never heard the alpine components before, and the other day i heard these speakers by infinity, REF6000CS 6-1/2" Two-way component system. They had a nice bass sound and the tweeters were very nice sounding too, but which would be better, the infinity's or the alpines? I'm not sure how loud i can push the infinity's, i know you can push the alpines a good amount though, enough for my listening pleasure, and help would be appreciated. Also just saw the infinity Kappa Perfect6.1 component system, that better then the other ones?
