2014 Kia Optima
Much better than factory speakers, but these are not there yet. I set the equalizer settings to flat. 90% percent of the sound was coming from the tweeters. I lowered the tweeter setting and cranked up the bass. This sounded much better, but distorted the sound on my rear speakers. Still have the factory head unit. The JL's sound much better than the factory speakers, but the sound is not balanced or musical. I expected more from speakers at this price point from a top name company. I really like JL subwoofers.
Pros: Much better than factory
Cons: Not a good match with factory head unit.
