Good, not great.
2016 Jeep Wrangler
Crutchfield Customer Review (What's this?)
The JL Audio C5-525x speakers work great in my 2016 Jeep Wrangler Sport. I placed them in the sound bar in front of the passenger seats. The 2016 model soundbar can also house the C5-525 with separate tweeters. The fit was perfect with the Crutchfield mounting brackets. The factory speakers are 6 1/2" but have a very shallow magnet so a better performing 6 1/2" might not fit properly. installation was simple. Wiring to the factory harness was again very simple to the crossover. The speakers sound slightly better than the factory speakers with the factory head unit; BUT, if you can power these speakers properly with an amplifier, the sound would be much more solid. Best if paired with a subwoofer since the low end reach should be rolled off around 80 hz. The woofer really struggles to push for those 50-80 Hz frequency sounds so you might get a muddy and mushy mid-bass quality to some music. I am looking forward to getting an amp to feed more juice to these speakers and pair them with the JL Audio Slimline sub made for the 2 door Jeep Wrangler. Overall, good speakers but make sure you're allowing them to play nice with your entire system and not be the savior for a factory radio.
Pros: Easy install, perfect fit in my vehicle, clean look, great sounding highs and mids.
Cons: muddy mid-bass / non-existent reach into lower frequencies. Not a factory speaker system "savior" option without proper subwoofer component and proper amplification.
