Great set of components
2014 Kia Optima
Crutchfield Customer Review (What's this?)
I bought two sets of these components for the front and back of my Optima. They're all running off of a 4 channel Alpine pushing about 55-60RMS to each pair. I have the signal filtered at the head unit at 100HZ and a -12dB slope falling off into lower frequencies, and am not using the amplifier crossover at all. Gain is set to nominal, with no bass boost. The result is crystal clear audio, solid bass response, and louder than I can listen to with no distortion at all. I haven't really tried to use them for tons of midbass as I have a sub that does all of that for me. Awesome set of speakers and a definite upgrade from my old Polk Db series. Added bonus that the crossovers on these are tiny and can be mounted just about anywhere with no problem.
Pros: Great speakers, unique style, and easy to hide the crossover just about anywhere.
Cons: I guess the low RMS rating might be problematic for some 5 channel amps if you want a huge sub.
