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.

lost some volume

Written By Anonymous, Wis Dells, wi on Sunday, July 05, 2015

Lost some volume compared to my factory speakers. Speakers sound good though.

Cons: Not as loud.

Extremely easy installation with the free vehicle specific brackets that were included. The speakers sound amazing for how inexpensive they are and free two shipping, can't beat that.

Work Well

Written By Tom G, Illinois on Thursday, July 02, 2015

Crutchfield Customer Review (What's this?)

Worked like a charm. The factory 6.5's went bad and I replaced them with these. They're loud and clear sounding. For the price, it's hard to have a bad thing to say about them. The bracket that Crutchfield sent me worked like a charm with only small modifications.

Pros: Loud, Clear, CHEAP

Cons: Not a ton of bass.

Very good replacement speakers

Written By Joel, Washington on Wednesday, July 01, 2015

Crutchfield Customer Review (What's this?)

I had a front speaker in my 2007 Acura MDX blow out and these speakers are a great replacement. They fit just fine in the front door speaker wells and the Crutchfield installation kit worked great.

Pros: Much better that the OEM speakers. Easy fit. Inexpensive.

Cons: None that I can think of.

Crutchfield Customer Review (What's this?)

These are coaxial speakers. They sound good at low & high volume levels. I don't know the impedance, but sound balance is about right between these and the OEM tweeters in my 2004 Colorado. I hope they last a lot longer than the originals.

Perfect for 2000 Honda Accord

Crutchfield Customer Review (What's this?)

My first aftermarket speakers

Pros: Perfect replacement for the stock door speakers. I've heard some speakers stick too far back for the window or internal door parts, but these installed perfectly.

Cons: None that I can tell. Maybe a bit weak on the bass.

Nice speakers.

Fit nice in my 93 Honda coupe. Great upgrade from stock speakers. Had to midis the front a little but furs nice behind the door panel. Rear was no problem at all.

Nice upgrade.

Written By MGBguy72, Vermont on Wednesday, June 24, 2015

Crutchfield Customer Review (What's this?)

These speakers were a nice upgrade from the original speakers of my 2006 Honda Accord. Crutchfield's speaker and wiring adapters make the install very easy. My only "complaint" is that the Crutchfield instructions do not mention the need to disconnect the electrical connections (window and door locks) to allow access to the front speakers.

Crutchfield continues to be my "go-to" seller for home and car audio.

Pros: Speakers are definite upgrade from the factory originals.

Cons: A minor downgrade for the lack of mention of the electrical (dis-)connections (windows and door locks) on the 2006 Honda Accord in accessing the front door speakers.

Kenwood 2 Way 6.5" Speakers

Written By mdh77, Ohio on Thursday, June 18, 2015

Crutchfield Customer Review (What's this?)

These speakers sound decent. I gave them a 4 because of the cost in the outlet and have nice features, but don't expect huge, amazing sound. You do get what you pay for. They are a good, low cost upgrade over the stock full range speakers in my teen driver's Jeep Liberty. We replaced the stock speakers and head unit and for a total investment of $200 bucks it is a very nice upgrade. If I were doing it over, I'd probably spend an extra $50 bucks total and get the Kicker or Polk speakers as I think I would have liked the performance a little better.

These speakers really don't produce any bass. You can get some with the loudness and "super bass" settings engaged on the new receiver, but with more than 1/3 volume you start getting distortion from the speakers. They have a very small magnet structure...I think they are actually lighter than the stock speakers. They work best when being gentle with the bass settings. The mids and highs are actually quite smooth and sound much better than the stock speakers. I like the clarity of the sound compared to stock full range. For improved sound on a budget over stock, I would recommend them.

Pros: Price, price, price. Fit well, look nice, smooth mids and highs, much better than stock full range factory speakers. A good value.

Cons: Limited bass, prone to distortion if you "crank them up" with bass settings in the "plus" range.

So I got these speaker's to replace the worn out rotten speaker's in my daughters 01 Beetle. They sound rather well in the car. They s little short on low frequencies but they are not designed to reproduce them.

Pros: Great sounding Great fit Great build quality.

Cons: None to report

Crutchfield Customer Review (What's this?)

easy to install, a great replacement upgrade for the blown out speaker in my wife's 2007 subaru forester. I replaced the front door speakers only.

Pros: Excellent instructions and final product has better sound quality that the original speakers. Install took a little over 1.5 hours.

Cons: Drilling new holes in the door was not as straightforward as I would have hoped. be sure to have a sharp drill bit!

Better than Factory Speakers

Written By RM, Alabama on Monday, June 15, 2015

Crutchfield Customer Review (What's this?)

I bought these as a replacement for the tired factory speakers in my 2004 Honda Element. They sound great and install with minimal effort. The instructions said that I would need to cut the speaker cover and back-panel but thankfully, I was able to install them without having to do anything except for the drilling of new holes. They are a great choice if you want better sound but don't want to spend too much money.

Pros: Easy installation and economical

Cons: Limited sound depth

Not sure what everone else is hearing but...

Written By c, Hawaii on Monday, June 15, 2015

Crutchfield Customer Review (What's this?)

...even with low expectation I was disappointed. Bought these to replace disintegrated stock speakers in my 2005 2500 crew. Wasn't expecting much but was hoping for at least better sound than the blown speakers. to be honest it wasn't much better. about as much bass as the old speakers that had no surrounds left! in the defense of the speakers, im still using the stock deck (big part of the problem I hope) and the speakers were cheap! ordered a new deck and am hoping for the best.

Pros: Cheap!

Cons: Cheap!

Crutchfield response on Tuesday, June 16, 2015 It's not uncommon for people to report hearing less bass with new speakers. Factory speakers are often made of cheap, flimsy materials. When you replace that with a better quality speaker, it'll need a little more power than the cheap one did to produce the same amount of bass. Adding a new deck should help, and the bass (and all of the music, for that matter) that you do hear will be cleaner and more detailed.

Decent OEM speakers

Written By JG, Iowa on Monday, June 15, 2015

Crutchfield Customer Review (What's this?)

These made great replacement speakers for the rears in my 2002 Blazer, in the sense that they sound pretty much like the old ones. No improvement, except these work and sound fine. However, the mounting adapter simply did not fit the vehicle, nor did the the speakers -although I was able to get three of the four mounting holes close enough to make it work. This was somewhat disappointing as the mounting hardware is the reason I order from Crutchfield in the first place, but they are in and working,so I'm pretty happy.

Pros: Inexpensive, decent sound

Cons: Didn't fit properly

Written By knudsen, Indiana on Thursday, June 11, 2015

Crutchfield Customer Review (What's this?)

These speakers might be OK if you have a factory radio and failed door speakers. Not as an upgrade. Certainly not as part of a great stereo setup. 99 Jeep GK w/infinity, OEM whizzer cone speaker "full range"/one driver have a much flatter and frequency response, deeper usable bass, more high end. Seems impossible, but true. I did extensive testing with clean sign wave signals and an SPL meter, but they failed the music test first, and very obvious. So the claimed frequency response of 35 - 22k Hz is bunk in the real world. I'm sure there is some sound coming out at the low and high end, but it's tapered off-scale. I fell for Crutchfield's claim that old speakers are bad speakers. Upon removal, I discovered the infinities have no parts that should deteriorate from normal usage or environment. They are like the old 1960's speakers that never fail, unless blown out. No foam, no rubber, no plastic. I never had a negative thing to say about Crutchfield, but take the old speaker thing with a grain of salt. I am not turned off to Crutchfield. FWIW: The box says JVC/Kenwood, so expect JVC quality now. Buy something better. Blaupunct, Sony, JBL, etc., avoid foam surround if you want them to last. Returning and keeping the OEMs. Not worth tearing the doors apart again to install something better, unless OEMs eventually fail.

Pros: Fit the hole Not foam surround Bling if you surface mount, but they all are nowdays 2 way does not block the woof like a 3 way does, blocking less bass in theory, but in practice there is nothing to block. Clear sound Perfect Yugo upgrade or gift for a bad mother-in-law

Cons: weak low end weak high end in my application, not worth the installation effort if they were free old OEM speakers sound better in all aspects 6 year old 5-1/2" sony xplods sound better in all aspects ($20 local retailer special) in my '90 Range Rover with Sony Xplod receiver (Crutchfield)
