I need new speakers for my car and I'm a circuit city sales associate. The cc i work at doesnt' carry the momo line of polk speakers or the kappa line of Infinity speakers but I can order either of them for very cheap. I drive a 92 nissan sentra with a Blaupunkt San Jose head unit and would like to avoid buying an amp. I want crystal clear sound with decent bass, and I'm a little afraid of the infinity's because i know their home speakers are awfully bright. I'm debating between four Polk mmc650's or four Infinity Kappa 63.5i's. I'm looking for any opinions any of you might have. And I'll accept, "whatever you do, you have to get an external amp" as a valid reply though only with reasons to back it up, i.e. powering either speaker, because of the low wattage given by my Blaupunkt will result in me damaging the speakers.
Thanks for your replies.
