6.5" coaxials

Upgrade on a budget

So, you're finally ready to do something about your ragged factory speakers. The beauty of Kenwood's Sport Series speakers is that you can seriously improve your sound without breaking the bank.

Sweet sound

The KFC-1665S 6-1/2" 2-way speakers feature polypropylene cones that will enrich your music with all the midbass and midrange details, while the 1" balanced-dome tweeters will make high notes soar. Kenwood also includes sharp-looking grilles in case you're doing a custom installation in your vehicle. Finally, you can enjoy your music the way it was meant to be heard, with clarity and emotion.


  • 6-1/2" 2-way speakers (pair)
  • polypropylene woofer with treated cloth suround
  • 1" balanced dome tweeter
  • grilles included
  • power range: 2-30 watts RMS (300 watts peak power)
  • impedance: 4 ohms
  • frequency response: 35-22,000 Hz
  • sensitivity: 92 dB
  • top-mount depth: 1-11/16"
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

  • Two 2-way speakers
  • 2 Grilles
  • Two 12" Lengths of speaker wire (each has female quick-slides on one end and bare wire on the other)
  • Eight 1" Self-tapping screws
  • 8 Speed clips

Product Research


Tweeters: Each speaker has a 1" PEI balanced dome tweeter. A semi-dome tweeter has a dome placed inside a cone. Balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter. PEI (Poly-Ether-Imide) is a polymer film that produces a wide soundstage for superior imaging.

Mounting: The speaker basket has multiple mounting holes and is designed to fit a standard 3-hole 6-1/2" application, Ford's 4-hole 6-1/2" application, and a standard 4-hole 6-3/4" application. (When mounting in a 6-3/4" application, use a speaker baffle to seal the inner ring of screw holes.)

Written By Great, Arlington tx on Monday, March 30, 2015

Great speakers. Sounds amazing I bo 2 pairs.

Pros: Good Quality and they're awesome to listen to it's very clear and it's a good thing to have

Cons: I haven't ran into any Collins for the speakers but they're good

Good for the price

Written By 53fireman, Pennsylvania on Sunday, March 29, 2015

Not bad for 2 way 6.5" speakers. Very basic, but they work and sound good which is what counts.

Pros: Looks, price, value.

Cons: None yet

Good replacement speaker

Written By JRo, Washington on Sunday, March 29, 2015

Very good replacement speakers.

Pros: These were one of the few replacement speakers available to fit my 2008 Honda CR-V LX because of the narrow space available inside the doors. They sound better than the factory speakers, especially in the mid- to high-range. They are a excellent value for the price for someone who wants an economical car speaker upgrade in a vehicle like the the Honda CRV-LX, which is the base model of the CR-V line, which comes with basic small magnet, single cone factory speakers.

Cons: The bass-range is a little weak when compared the the mid- and high-range. Boosting the bass with the equalizer helps but I suppose if you want great bass without buying a very expensive subwoofer then you would probably have to buy a component speaker system, which still might cost several times as much as these speakers.

Great Replacement

Written By Dave R, CT on Sunday, March 29, 2015

I have an 04 Jeep Grand Cherokee, I bought these to replace the 4 factory Infinity door speakers in my Jeep because the factory speakers were not working. After I installed them the sound was great. I have a Kenwood unit. The speakers are running throught the factory amp. I do not have a sub woofer, I choose not to, and the sound is perfect for me.

Pros: Great sound, nice highs, mids and lows.

Cons: None

Crutchfield Customer Review (What's this?)

The speakers are definitely better then I expected but I should have known this they are Kenwoods. Great high's and mid's the bass is there but if you really want bass bass a sub and amp Is what you need. Overall pretty impressed and as for the Crutchfield team I am very impressed. One of my speakers was making a crackling sound, so I called and before I could say to much a new set was on its way. A+++++ on customer service with these guys they have a customer for life. Sure I could have got these a little cheaper somewhere else but after the wire harnesses and speaker plates I got for free with my order I actually saved money. And again with the customer service, a piece of mind is priceless. Thanks again Crutchfield.

Speakers sound amazing. However they did not fit in my 2012 Lancer with the adapter, had to chop the stock speakers and use them as a mount. Aside from the fit, i have no complaints.

Pros: Sounds Great

Cons: Doesn't fit in my car with adapter as mentioned in the installation details that comes up.

Kenwood 1665s

Written By Drew, Hawaii on Friday, March 13, 2015

Crutchfield Customer Review (What's this?)

Put these in the front and back of my wife's 4dr lb yaris. They're just like every other bottom of the line kenwood speaker I've installed, which is a lot over the years. Paired with a kenwood deck they get loud, less bass than stock, better mids and highs, kinda bright.

Pros: High sensitivity, they get louder than any other cheap speaker I've heard without needing an external amp.

Cons: Bass sucks, but doesn't really matter if you're adding a sub. I knew this would be the case and I paired it with a polk 8" sub.

2013 GMC Sierra Extended Cab

Written By Justin R., Barre, Ma on Tuesday, March 10, 2015

Crutchfield Customer Review (What's this?)

I replaced my factory door speaker with these Kenwoods. I took my time, installed some dynamat around the speaker area of each door. The front doors came with the replacement brackets, which were decent and did the job. The rears, in order to make these or any other aftermarket speaker fit, you have to be crafty. But that's why we have online tutorials. After the installation, I was surprised at the difference in sound. They sounded great. No, they're not super high end 6.5's but for the money, a pretty good deal. I was pleasantly surprised at the quality of sound coming from them. You're not going to get tons of bass, but you'll get a good, full sound. Definitely recommend them.

Pros: Price, value, mounting holes, overall quality

Cons: Nope

My rear speaker was blown since I had my truck so I ordered these after looking at the review. Since I do not have anything to compare them with I can't. But I can say they do the job and came with everything I needed. Fast shipping. I put them in myself in 30 mins and I do not have any previous installation experience.

Pros: Nice sound, came with everything needed, easy install

Crutchfield Customer Review (What's this?)

I put these in my 2000 chevy silverado 4 door. I have an aftermarket Pioneer headunit in the vehicle and I guess the factory speakers could no longer handle the added power. I left the tweeters in the doors and just replaced the 6.5" speakers. I would get very bad distortion when I turned the radio up and couldn't use any of the bass, eq, or loudness features. It took less than an hour to install these with the help of an online video showing how to remove the door panel. They sound great and I am glad I didn't spend twice the amount on speakers that might be marginally better. I can now use all the features of the radio and enjoy some bass and crisper sounds. They sound better than the stock ones ever did and are a nice and needed upgrade from the tired old factory speakers. I have always had good luck with kenwood products. If your factory speakers are getting bad this is a perfect choice.

Pros: Can't beat the price and sound for a nice set of speakers, plus Crutchfield gives you everything you need for install

Cons: I can turn my radio up louder now which probably doesn't help my hearing.

great sound little price

Written By 08Cobalt, San Antonio, Texas on Friday, February 20, 2015

Crutchfield Customer Review (What's this?)

I installed these in a 2008 chevy cobalt, notorious for having bad speakers. Both my fronts were dead. Install was easy took about 30 minutes, only needed to drill 3 small holes each. The free installation items (adapter plates and wire adapter) for my vehicle worked great. The speakers sound nice and for less than OEM speakers these are a much better replacement. Nice crisp sound, not a lot of bass but enough to vibrate my door mirrors ever so slightly.

Pros: Price, Sound, Better Looking then OEM

Cons: They fit better rotated about 20 degrees, not straight up. But they are behind the door grills so you can't even see that.

Decent for the money

Written By LouLoc, Phoenix, AZ on Thursday, February 12, 2015

Crutchfield Customer Review (What's this?)

Not a whole lot of bass, but nice crisp sound. A definite improvement over stock speakers in my '07 Suburban. I didn't want to put a whole new system, I just wanted better sound from the stock deck and these fit the bill. I'm happy with them. You can't beat the deal from Crutchfield. With the speaker mounts and the speaker wire adapters included its a no brainer. The master install sheet was great. We swapped all 4 door speakers in just over an hour. A local shop wanted to charge me $100 to do it.

Pros: Crisp sound, economical.

Cons: Low bass

Written By Mark S., Texas on Friday, February 06, 2015

I have a 2000 Ford explorer and these were definitely an upgrade, but not by much. the clarity is good considering the price. No bass at all, but I wasn't expecting much. I ordered 2 pairs of the 5-1/4" ones, but they gave me the 6-1/2" as one of the pairs instead and they didn't fit naturally so i had to do a little custom fitting to get it fitted. I would look into higher quality speakers if had the money.

Pros: decent for the price. decent clarity in the mids and highs.

Cons: no bass. the price could be cheaper considering the quality.
