I bought some Alpine Type-R 12s around Christmas time and haven't hooked them up yet. I've read around that people thought the Infinity Perfects were really good for sound quality which is basically what I'm mainly looking for. I'm sticking between these 3 models because I can get them for about $100 a piece brand new. I'm gonna be running them off an Alpine MRV-1507. I'm just wondering if I should switch it up before I have a box built.
