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.

  • 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

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.

Crutchfield Customer Review (What's this?)

I replaced the factory speakers in the front door of my 02 WRX as they had blown out. This speaker was super cheap and sounds better than the previous speakers.

Pros: Loud, good range Cheap

Cons: Slight distortion between lows and highs. The bass sort of washes out the treble at times. I mitigate this with my radio settings.

Great factory replacement speaker

Written By Mike Jenkins, Kentucky on Sunday, August 16, 2015

Crutchfield Customer Review (What's this?)

Replaced my old dry rotted truck speakers. These little speakers sound great. Much better than the factory speakers ever did. Plenty of sensitivity to sound good with low powered factory units. Yet can handle the power of aftermarket systems as well.

Pros: Sensitive and sounds great. Highs are very crisp and clear

Cons: Very very little bass

Crutchfield Customer Review (What's this?)

Speakers are slightly better than stock. If you're adding a sub with 300 rms or more I'd go with some better ones. Overall happy for the price but will probably upgrade in the future.

Pros: Just ok.

Cons: Just ok.

Good value, OEM replacement

Crutchfield Customer Review (What's this?)

Good OEM replacement. Clear highs and mids, decent bass. Overall a great value, although I wanted more so I've already replaced them with components.

Pros: Value Clarity

Cons: Low end

Crutchfield Customer Review (What's this?)

Online help was great. They sent me all the additional accessories to instal . I did not need mounting brackets for the rear doors, but had them anyway . Sound quality is soooooo much better than th e stock speakers I took out. Great service from staff!

Pros: Good sound

Cons: Install instructions not all correct for rear speakers

Great deal

Written By Rod J, Nevada on Wednesday, August 05, 2015

Crutchfield Customer Review (What's this?)

Great deal for the price. Installed an aftermarket radio that made the factory speaker crackle at higher volumes. Crackle went a way after installing the Kenwoods. Very satisfied with the price and the product

Pros: Great speakers for the price. Better than factory speakers in this case

Cons: Mounting screws were a little suspect. Use nuts and bolts to secure to the mounting bracket

Kenwood KFC-1665S - 2002 Jeep Liberty

Written By BryanB, Indiana on Monday, July 27, 2015

Crutchfield Customer Review (What's this?)

Fantastic speakers. Have installed these in other vehicles and came back for more. Great speaker at any cost and these are very reasonable. These replaced all (4) infinity speakers that failed. No need to buy the infinity replacements from the factory...these are a quick and easy install once you figure out what goes where. No instructions and no harness available. I drilled and zip tied the infinity amps to the inside of the front door panels and everything works great. You have to use the factory amps for the rears to work--especially the drivers rear door. I cut and spliced wires only to find that i didn't need to cut and splice wires--good learning experience. Many hours later after re-doing what i had undone, and it's fantastic!

Pros: Sound great

Cons: no harness and no instructions.

Decent sound

Cons: Not enough low range bass.

decent speakers for the money but not much bass sound

Kenwood KFC-1665S

Written By 70GTX426, Indiana on Wednesday, July 22, 2015

Crutchfield Customer Review (What's this?)

Sounds as good or better than the stock speakers that they replaced.

Pros: Good advice on selection from Crutchfield, every thing needed to complete install was included.

Cons: Instructions could have been more detailed on exactly what tabs to remove from speaker adapter, one of the electrical connectors was difficult to connect to the speaker while pushing it on it bent one of the tabs on the speaker, but due to my outstanding ability to correct manufactures lack of quality control the problem was corrected.

Sounds Just Fine!

Better than expected

Written By Brian, Missouri on Saturday, July 18, 2015

Crutchfield Customer Review (What's this?)

These replaced the factory front door speakers in an '07 Toyota Corolla. Coupled them with a KDC-158U - Kenwood Single DIN In-Dash CD/MP3 Stereo Receiver with USB Interface and Kenwood KFC-6965S 6 x 9 Inches 3-Way rear speakers. The 6 x 9's are as expected. Moderate bass and clean mids. The head unit is excellent. The front 6.5's are much better than expected. I did do my best to seal up the door and made sure they have a good seal, but they are completely exceeding my expectations. Solid low end and very clean throughout the spectrum. Not trying to compare to JL's or anything but for $40.00 they can't be beat. I've installed a lot of equipment both personally and professionally. This was for my wife's car because I couldn't even stand to have the radio on when I was in it. The stock system leaves a lot to be desired. I also added a 8" Rockford sub in a custom built and tuned ported box. Running that on 150 watts and now I actually enjoy driving her car. Everything is crisp and clear well beyond any comfortable listening level. Had the old stuff out and the new stuff installed and tweaked in less than 3 hours including running all wiring for sub/amp in trunk.

Pros: Value, Quality construction, buying from Crutchfield and getting the adapters and wiring harnesses to make installation a breeze.

Cons: The stamped and formed sheet metal nuts that come with the Metra speaker adapters are a bit questionable. They tightened up and felt secure but being inside a door where I can't get to them to see if they stay tight I opted to use my own nylon locking stainless nuts.

Good Value!

Crutchfield Customer Review (What's this?)

Had two blown stock speakers in a '03 BMW 325i and didn't want to break the bank so these were the best bet. Huge improvement but remember my stock speakers were torn. Drop in replacements with included brackets. Great sound for the money!

Pros: Good sound for the money

Cons: Little bass

Very good entry-level speakers for the price.

Written By Jean-Paul D., Louisiana on Monday, July 13, 2015

Crutchfield Customer Review (What's this?)

First, it's important to understand, these are entry level aftermarket speakers. Don't expect ultra-premium quality. That being said, these speakers are very good for the price. They are on par with cars that come with good (premium?) stereos from the factory. If you already like the way your factory stereo sounds, these probably aren't going to be a significant upgrade. But if you have obviously poor-quality speakers or your speakers are damaged or blown, these make great replacements. I put 4 of these in my Saturn Vue (which had a terrible factory stereo system) along with a Kenwood stereo (KDC-X599) and they sound great. I did have to turn up the bass and down the treble, but I'm very pleased with the results.

Pros: Inexpensive. Sound on par with a quality factory system No install problems.

Cons: These are entry level speakers. They are very good for the price, but don't expect audiophile sound quality.

good speaker for cheap price

2002 GMC SIERRA crew cab. easy to install and sound good for a cheap price. The rear speaker adapter didnt work but these speakers worked with the factory mount with some finagling

Pros: cheap & sounds better than blown factory speakers

Cons: rear speaker mount was not compatible with crew cab but you can cram the the new one into the old mount with a little work

Crutchfield Customer Review (What's this?)

These speakers are exactly what I was looking for. They are an inexpensive way to have upgraded my factory speakers on a budget. They sound great and are durably built. I suggest for a still better sound to enclose the speakers in a foam surrounding that encloses the speakers and improves their performance. I found this speaker enclosures at another retailer.

Don't buy these speakers

Written By Lew, Florida on Friday, July 10, 2015

Crutchfield Customer Review (What's this?)

I bought these speakers to replace the OEM woofers in the two-way door speakers in my 2001 Silverado 1500. Crutchfield offered the mounting and wiring harness adapters for free so I ordered them. Most of the ratings were favorable so I took a chance. The next day on my way to work it was immediately apparent that I had made a mistake. Within a few minutes I was trying to adjust out the harshness and brightness of these speakers and their lack of bass. It was not possible to make these speakers sound satisfactory with the settings available on my OEM radio. Crutchfield technical support was very helpful and reminded me of their 60-day guarantee. I like the sound of the OEM woofers but I had three out of four replacements from a different online retailer develop open voice coils. I am hesitant to buy any more of the garbage Delco OEM speakers from Mexico. I may try an upgraded replacement from Crutchfield. It is just such a hassle to replace these things.

Pros: Cheap

Cons: Harsh and fatiguing sound.
