Go with infinity. From what I have heard Kicker only makes good sub and amps but not speakers. I have heard a set of kenwood 6.5s, they werent horrible but werent the best. Infinity is so underrated. THere stuff is phenominal.
Infinity 6002i or 60012i depends on money your looking to spend. I got the 002i's great speakers just would of been better if i got another pair for the front but its okay.
infinity 6012i brandnew fleamarket about $50, I think cheaper on ebay. Definately worth the price, buy a half-decent amp to power them and you'll be rocking.
ya definately go w/ infinity they're a great bang for your buck speaker. i've heard kicker speakers components and such and they sound terrible very loud and accurate they just put out loud noise not a very msuical speaker at all.
