  • Great fit 2017 kia sorrento
Style: 6-1/2" 2 Way Speakers
I recently upgraded my car audio system with the Kenwood KFC-1666S 6.5" 2-Way Car Coaxial Speakers, and I am thoroughly impressed. Here’s my review: Perfect Fit The installation of these speakers was a breeze. They fit perfectly into the factory speaker locations without any modifications needed. This made the upgrade straightforward and hassle-free, allowing me to enjoy the enhanced sound quality in no time. Exceptional Sound Quality I’m blown away by the sound performance of these speakers. They deliver clear, crisp highs and deep, rich lows that significantly improve the overall audio experience in my car. Whether I’m listening to music, podcasts, or navigating with GPS directions, the sound is immersive and balanced. Sound Field Enhancer The built-in Sound Field Enhancer technology truly enhances the audio output. It creates a more expansive soundstage, making the music feel more dynamic and engaging. The clarity and detail in the sound reproduction exceed my expectations for speakers in this price range. Durability and Build Quality The Kenwood KFC-1666S speakers are well-built and feel durable. The materials used are high-quality, and the construction appears sturdy enough to handle regular use and vibrations in a car environment. I expect these speakers to provide reliable performance for a long time. Value for Money Considering the sound quality and performance enhancements these speakers provide, they offer excellent value for money. They outperform many factory-installed speakers and other aftermarket options in their class, making them a worthwhile investment for any car audio enthusiast. Conclusion In conclusion, the Kenwood KFC-1666S 6.5" 2-Way Car Coaxial Speakers have exceeded my expectations in terms of fit, sound quality, and overall performance. They are easy to install, deliver exceptional audio clarity with a wide soundstage, and are built to last. Whether you’re upgrading from factory speakers or looking to enhance your car audio experience, I highly recommend these speakers for their outstanding value and impressive sound. ... show more

  • quite fantastic for the price range
Style: 6-1/2" 2 Way Speakers
Sadly mine was delivered (in the consumer packaging box) in a thin bag... no bubble wrap, just a plastic white bag and of course the big ding right in the center of a grill. Luckily, I'm not needing the grills, and the box itself (while pushed through) encased two styro-foam protetcants for the speakers, and the grills were over the speakers...so, the speakers themselves are fine. Everything else is fine. The box and one grill took all the abuse and they should've used at least bubble wrap bag (or a box, as the kenwood box is as thin cardboard as it gets). These do come with everything we need to install. These also are high enough sensitivity to be able to get good volumes from a weak head unit. Using an amp might be pushing them too much, so ensure the amp is set properly. Either way, these are loud enough to be twice as good as the factory car speakers, and for 29 dollars, is incredibly good value. They do have decent mids, and mid-lows but shine in the upper mids to highs. Mine are set to 120hz but were going great at 80hz and at lower volumes could probably handle 50-60hz but I don't want to overheat them for too long. If you need inexpensive, clear sounding, loud replacement speakers, these will be great. The speakers are entry level and probably the best low budget there is. ... show more

  • Great speaker, not much bass.
Style: 6-1/2" 2 Way Speakers
These speakers are a good value and sound better than my stock speakers, although the bass is not very impressive. If bass matters to you at all I would recommend passing on these. That being said, they do sound good and are a decent option where low profile speakers are needed.

  • Fits and works great in my 2003 Honda Element
Style: 6-1/2" 2 Way Speakers
The title says it all. With the wiring harness I got separately, install was super easy. No adapters needed. They sound great, but I’m sure they will sound even better when the new head gets here!

  • Crisp and clear

It’s an upgrade for sure. 2011 civic rear speakers were shot. These sound good and were a great value. Not subwoofers though. So temper your base expectations

I had put these in a portable Bluetooth speaker that I had built and the sound of theseare incredible. They are so smooth and clear sounding. I will be looking to buy more for more speaker building projects.
