So I've been trying to decide what speakers to put in my car. I've already decided on an alpine head unit amps and type-r sub. Now it's just a matter of which speakers. I heard the PA's alone and they sounded good. Can't find the infinitys around here anywhere, all they have is reference. The local Best Buy however had the entire setup with all alpine and it sounded good. Plus I can get the alpine for about 100 less than the other two.
