Just as the title of this review suggests......these Kicker 6 X 9 three way speakers are a great value, they sound amazing, the build quality is awesome, and the price through Crutchfield is excellent.
I've had these installed in a 2006 Nissan Altima 2.5S sedan in the rear deck for a little over 9 months now. Despite Crutchfield saying that they will notfit.....they do. I had them professionally installed, and the installer said that he did not need to make any special adjustments or modifications for them to fit.
Immediately, they were an upgrade over the stock Clarion 6 X 9 speakers that came with the car. The sound and range were much improved....the bass sounded deep, responsive, more true and natural.....and the mids and highs were a HUGE improvement over the Clarions. Volumes that used to be near distortion level with the stock speakers are now much clearer through the same JVC KW-NT3HDT Navigation receiver that I purchased through Crutchfield last year. I have these speakers paired with a set of Kicker KS6.2 6-1/2" components in the front, and the sound is truly amazing. I don't have a sub or an amp currently installed, and it sounds terrific. I'll probably add an amp at some point, but the bass that these produce is good enough that as long as you aren't trying to shake the fenders off of your car or win contests, they will definitely get the job done. (I probably won't even add a sub to go with them)
Bottom Line: Yes, I would recommend these speakers.
Pros: great value, amazing sound, awesome quality, and excellent price
Cons: Nothing concerning the speakers....but the Crutchfield guide that "shows you what fits" says that they will not fit in my car (and other vehicles).....but they do.
