Kicker 41KSC684

Slim fit

These KS Series speakers are some of the most installation-friendly Kicker speakers yet. These low-profile speakers feature a reduced mounting depth, making them a match for almost any car.

Pump up the volume

While the low profile is an elegant asset, you'll find the real beauty of Kicker's KS Series speakers inside. The 41KSC684's highly sensitive design conjures hefty volume even from low-powered factory radios. So, you'll be able to enjoy every bit of their natural sound, starting with a full midbass and midrange experience from the 6"x8" polypropylene woofer and its powerful magnet. You'll also hear subtle vocal and instrumental details from the silk dome tweeter, giving your music a dimension that factory speakers just can't manage.


  • 2-way car speakers (pair)
  • 6"x8" (5"x7") polypropylene woofer cone with rubber surround
  • 3/4" silk dome tweeter
  • power range: 2-75 watts RMS (150 watts peak power)
  • frequency range: 45-21,000 Hz
  • sensitivity: 90 dB
  • top-mount depth: 2-5/16"
  • impedance: 4 ohms
  • grilles not included
  • 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.

Good speakers, easy install

Written By James S., Houston, TX on Thursday, November 19, 2015

Crutchfield Customer Review (What's this?)

I installed four of these speakers into my 2012 F-150 XLT Supercrew. Installation was easy and straight forward and the wiring harnesses make it simple, just plug and play. The speakers are superior quality to the OEM speakers. Clarity is good. Bass in the mids is good, but a little lacking in the low. I plan to install the Sound Ordnance compact sub shortly after Christmas to give it that extra bump.

Pros: Easy install, plug and play, superior sound

Cons: None

2011 F150 Limited

Written By Ryno918, Oklahoma on Saturday, September 12, 2015

Crutchfield Customer Review (What's this?)

At higher volumes with bass the stock speakers have major fade. My other car has KS 6x9's and 6" kickers in it with a 12" sub and decided after reading other reviews to give these a try. Have to say it's 100% better. The bass, the mids. Was a great choice. WILL recommend these to my other friends with F150's..

Pros: Easy installation. Best hour I have spent Installing 4 speakers.

Cons: Drivers door was a pain was all.

Good speakers for the price

Great improvement over factory

Written By Zdad, Arkansas on Tuesday, August 18, 2015

Crutchfield Customer Review (What's this?)

Plug, play and be impressed by the difference. The stock Sony speakers in my F150 had no midrange whatsoever, so I got these and I'm surprised by the amount of solid bass they have as well as the improved midrange. Great purchase.

Pros: Easy install

Cons: no "kicker" badges to replace the sony badges on my doors.

Quick fix for OEM

Written By jG, Arkansas on Thursday, August 13, 2015

Quick and painless upgrade to OEM that makes a serious improvement in sound quality. With the included wiring harness adapters, the hardest part was getting to the screw behind the door handle. I got a set of 4 installed after work and noticed a huge difference as soon as I turned the music back on. Very satisfied!

Pros: Easy install. Great sound quality for the price.

Cons: Um... no optional foam "spacers" for the front. That's purposely LOOKING for a con, though.

Awesome upgrade

These speakers are as advertised. No tweeters needed with this set of speakers.

Pros: Great highs and lows. The sound is pure. A great purchase.

Cons: none.

will not buy kicker anymore

Written By dw, ont on Wednesday, June 17, 2015

Had these kickers in for 6 months before I replaced them they are terrible speakers. The head unit was only putting out 25w RMS and that was too much for these speakers. Poor sound as well.

Written By Rich, Pittsburgh, PA on Saturday, June 13, 2015

Crutchfield Customer Review (What's this?)

Easy to install, good sound for a simple replacement speaker.(Just using radio power). A subtle increase in sound quality, but for the money, a pair, this is to be expected.

Pros: Good value, works as advertised. Very simple, drop-in install.

Cons: None.

Great speaker

Crutchfield Customer Review (What's this?)

These speakers are some of the clearest that I've put in my truck. They are very clear with no distortion when given the power that they need.

Pros: Clear Fit two sizes 5x7 and 6x8 Good bass if that's what you want but are great for mids and highs also

Crutchfield Customer Review (What's this?)

I installed these speakers in all 4 doors of my 2013 ford f150 xlt ext cab. They are running off of my factory head unit. They sound louder than my factory speakers but i cant tell a difference in clarity too much. Other than that, i like them a lot.

Pros: loud speakers, great quality

Cons: Not too much more clear than factory speakers

Kicker Replacement Speakers

Written By SCS, Pittsburgh PA on Monday, May 04, 2015

Crutchfield Customer Review (What's this?)

Marginal improvement in sound over the stock speakers. The kickers dropped right in and look good. Would have liked to have more of a sound distinction from the stock offerings.

Pros: Nice package. Easy install.

Cons: Not enough audible distinction from stock.

Kicker KS Speakers

Written By Austin H, Rutherfordton, NC on Wednesday, March 11, 2015

I got these speakers for my 02 Ford Ranger they fit great and they sound great, definitely worth the price, easy install

Pros: Install, Sound, Price

Cons: None at all

Very good speaker for the price

Written By Kevin, Colorado on Monday, February 23, 2015

Crutchfield Customer Review (What's this?)

These are good, solid speakers. Not the top of the line, but for the price they sound great. They're far better than the original equipment speakers - I don't know a lot about speakers, but these weighed a lot more than the originals in my 2012 Escape. The magnet was about four times the size, and the cone is made of a much more durable material - the originals were paper. I'd recommend them to anyone looking to replace the original speakers with something that sounds much, much better but doesn't cost an arm and a leg. I was replacing a blown speaker and these were a definite upgrade over the originals.

Pros: Magnet is much larger and heavier than originals. Cone is much more durable. Installation was pretty easy - these speakers fit exactly in place of the originals in a 2012 Escape front door. Sound much better than the originals.

Cons: Can't think of any.

Worth the price

These speakers sound better than factory speakers, but just marginally. Don't expect deep bass and cirspy highs

Pros: Easy to install

Cons: None

good factory replacement

Written By Anonymous, Caldwell idaho on Saturday, December 27, 2014

Crutchfield Customer Review (What's this?)

I usually buy infinity but figured I would buy 2 sets of 6x8's for my 2003 ranger supercab because of a free kicker headphones with the special they were having. I installed them and they sound better but not on the same level as infinity reference I usually buy. I have a jvc aftermarket receiver.

Pros: Good bass response

Cons: Highs seem to be lacking.

Great speakers they really are an improvement from the stock in my ford expedition.

Excellent Quality!

Written By Anonymous, Philadelphia on Wednesday, October 22, 2014

Crutchfield Customer Review (What's this?)

These speakers were such an upgrade from my factory speakers. I installed them in my Taurus recently, and they were so much easier to install than I imagined. The bass is excellent on them, and you can really hear every single detail in the high notes also. I use them every day and my car and I could not be happier! I highly recommend getting these, and they are very affordable!

Pros: Great bass, detailed treble, powerful, affordable, easy to install

Cons: Maybe make the bass a little more powerful. But it is still very good!

Cons: none

Solid cheap speakers good OEM improvement

Written By ruth, Ohio on Thursday, July 24, 2014

Crutchfield Customer Review (What's this?)

I bought these with a Kicker Hideaway sub for my super duty. These speakers are in the front and are powered with the factory headunit so Im sure they would sound better with a better source/amp but these are a drastic improvement to the OEM speakers. They dropped right in and the harness hooked right up to the factory harness. No splicing or cutting.

Pros: Inexpensive but sounds pretty good

Cons: None

Great product
