  • powerful sound!
The KENWOOD KFC-1666S speakers deliver impressive sound quality with clear highs and deep bass. Installation was quick and easy, fitting perfectly in my car.

  • Incredible Sound at an Affordable Price – Perfect for Easy Audio Upgra
I recently purchased the KENWOOD KFC-1666S 6-1/2" 2-Way Car Stereo Speakers, and I have to say, they have far exceeded my expectations. The sound quality these speakers provide is nothing short of impressive. They deliver crisp highs and clear mid-range tones, making my daily drives much more enjoyable. The bass, while not as deep as you might get with a dedicated subwoofer, is still solid for a 2-way speaker and adds a nice depth to the music. If you're looking for a well-rounded audio upgrade that really enhances your in-car listening experience, these speakers are an excellent choice. One of the best aspects of these speakers is how easy they are to install. I was able to get them set up in my car without any hassle, and they fit perfectly in the existing speaker mounts. Even if you're not particularly experienced with installing car audio equipment, you shouldn’t have any trouble getting these up and running. What really stands out, though, is the incredible value for the price. These speakers are very affordable, but the sound quality they deliver is far better than you would expect for something in this price range. It’s rare to find such an inexpensive option that still offers such high-quality performance. If you're on a budget but don’t want to compromise on sound, these speakers are a fantastic deal. Overall, I’m really pleased with this purchase and would highly recommend these KENWOOD speakers to anyone looking for a quick and easy way to elevate their car’s audio system without breaking the bank! ... show more

  • Pretty decent
Maybe it just me. I don't think it sounds as good as my Pioneer speakers, but it is not that bad I wouldn't recommend it. The sounds clarity is good and it is worth it if there is a deal on it.

  • Good quality for the cost
The info on the watts for the speaker is much higher than is on the speaker magnet. Shows 300 watts but has an RMS of only 30 Watts. Other than that it sounds great and was shipped with a lot of care.

  • Good enough for price
Sound quality isn’t great but works for a budget.

  • Kenwood sound
For the money, these sound good. Running off a pioneer deck in an overhead soundbar. They ship in manufactures packaging that showed up a little mangled, but all was well. I’m happy with the speakers.
