Here is my dilema, I think i blew my MB Quart door speakers cause the left side only keeps cutting in and out, sometimes it plays at half volume, sometimes it plays at half volume with static commin out, whatever, it sounds like crap. And its not the amp or RCA's i had them both checked out.

I am switching to focals next but I don't know which set to get. I am looking at the utopias (165w) or the new polykevlars (165 k2p NOT the regular k2). Just wondering if any of you guys know the real difference between the two other than price? Any weaknesses or strengths? Thanks again.
