Kicker 40CS654

It's time for an upgrade

Upgrading the old factory speakers in your car will give you a huge bump in sound quality, and Kicker designed CS Series speakers to get your sound system rockin' without breaking the bank. You'll enjoy your music even more when you hear all the details that your muddy-sounding factory speakers couldn't begin to reproduce.  

Built tough

Kicker's 40CS654 speaker set provides low-end from a tough 6-1/2" polypropylene woofer, with a polyester foam surround that will stay strong for years to come. The 1/2" PEI balanced dome tweeter takes care of the vocal and instrumental details that'll really bring your music to life. These speakers sound great powered by a factory radio or an aftermarket car stereo, and they'll really rock when connected to an external amplifier. Grilles are included.

Product Highlights:

  • 2-way 6-1/2" speakers (pair)
  • polypropylene woofer cone with polyester foam surround
  • 1/2" PEI balanced dome tweeter
  • power range: 2-100 watts RMS (300 watts peak power)
  • frequency response: 40-20,000 Hz
  • sensitivity: 90 dB
  • top-mount depth: 1-13/16"
  • 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.

Product Research


Polypropylene Woofer Cones: The Kicker CS-series speakers feature durable polypropylene woofer cones, resistant to moisture and temperature extremes found in automotive applications.

Ribbed Polyester Foam Surrounds: The ribbed polyester foam surrounds allow extended cone excursion for additional bass output and higher SPL.

1/2" PEI Balanced-dome Tweeters: The 1/2" PEI (polyetherimide) balanced-dome tweeters provide a smooth high frequency response with quick, detailed and spatially-correct imaging. The tweeters have strong neodymium magnets for higher power handling.

Mounting: In addition to fitting standard 6-1/2 and 4-hole 6-1/2 applications, the CS65 also has a standard 6-3/4 bolt pattern. However, if mounted in a 6-3/4 location the holes for the smaller pattern create an air leak, which must be sealed using a speaker baffle, or something similar.

2008 Tahoe factory speaker upgrade

Written By GQ, Pennsylvania on Thursday, March 26, 2015

Crutchfield Customer Review (What's this?)

My front left factory speaker went out. I emailed a Crutchfield team member & they found a solution. I only wanted to change the (4) door speakers,not the tweeters in the front. I like the Kickers. BIG improvement in sound quality w/o a big $$ investment. I would estimate a 50% difference in sound quality over the cheap paper cone factory speakers for not a lot of money. Thanks guys!

Pros: The Kickers came with the special GM mounting bracket and wiring tail. New speakers have poly cones, not paper like the factory junk from GM.

Cons: only self tapping screws were provided in the package. 1 1/2" long x 8/32 machine screws with locking hex nuts are needed to do the job right, IMO no worries, I had them in stock in the garage.

Great speakers, decided to throw power to them via an amp and that was a great decision to get good mid bass to complement my 10" sub.

Pros: Lives up to the well known positive Kicker reputation

Cons: None

This product worked perfectly in my 06 Accord EX V-6 6 Speed. The car needed mounting brackets and a wire harness that was supplied free when I purchased the speakers! It's vast and easy to use Crutchfield! No issues and speakers sound great. Now I just have to save a little more for the rear 6X9 speakers from kicker!

Pros: Cheap Fast shipping Included adapters and other gear

Kicker vs Polk

Written By BillyK, Tigard, Oregon on Tuesday, March 24, 2015

Crutchfield Customer Review (What's this?)

With a budget of $100 and my research done, I ordered a pair of Polk DB651s for the rear deck of my '08 Civic coupe. I couldn't have been more disappointed! For my application they did nothing well - no bass, no clarity, etc., etc. I called Crutchfield to get some insight as to why the Polks sounded worse than the cheap factory paper speakers and was immediately invited to return them for credit! I asked to speak to a tech first, who suggested I try a pair of the Kicker 40CS654 - for $30 less than the Polks - and he was right! Big improvement over factory and even bigger improvement over the 651s'. Another pair will find their way into the front doors for sure. Thanks for your great customer service.

Pros: Above average bass and clarity ESPECIALLY for the price.

Cons: There's always something better. (But paying more doesn't guarantee you'll get it).

Great speaker for the price

Crutchfield Customer Review (What's this?)

Great sounding speaker! If you listen to a lot of rock or country then this is the speaker for you, very high quality imo. but if you listen to a lot of rap and hip hop and like more bass I would suggest something else. Songs with tight bass sound great but looser bass,not so much. but I would imagine these would go great with a set of subwoofers.

Pros: High quality mids and highs

Cons: Bad sounding low end bass

kicker40cs654 Makes me wanna sleep in my car

Written By Sharae, East Point, Ga on Thursday, March 19, 2015

Crutchfield Customer Review (What's this?)

I am a woman and installed my own. I have a 99 Audi A4 1.8T that came with a factory amp attached to the right rear deck speaker. I enjoyed every part of the install. Had to fabricate a harness so the amp would stay up by the speaker. It has decent mid rang and if you keep the volume down the bass is awesome but i have two tweeters up front and two in back so im hoping after i install my aftermarket head unit, it will kick up a notch because then i can play with the sound more and open these speakers up. Love these speakers, to bad i cant get these in the front door without it interfering with my window.

Pros: Bass Easy install

Cons: Turning volume up drowns bass

Install in Roll Bar in 2014 Jeep Wrangler Unlimited

Written By CJ, Pennsylvania on Wednesday, March 18, 2015

Crutchfield Customer Review (What's this?)

Everything goes smoothly except for the bracket. The holes do not line up perfectly with the factory grill and therefore you have to adjust the bracket that Crutchfield sends with the speakers. This does not take much effort if you have the right tools. I have the Alpine sound system in my Jeep and I was not getting enough vocals with the factory roll bar speakers. These speakers added more all around sound and made my sound system sound more like surround sound. Cheap speakers with good quality and Crutchfield does an unbelievable job with customer service.

Pros: Great sound for a great price.

Cons: Installation can be somewhat of a hassle. But if you have patience it should not be that big of a deal.

Crutchfield Customer Review (What's this?)

I installed these in the front doors of a 2014 Ram 1500 along with Kicker 41KSC694 6x9s in the rear doors and Kicker 41KSC354 3.5s with 300 Hz bass blockers in the dash. The 6.5 inch speakers required and adapter which Crutchfield supplied with the order. Nice sound and a big improvement from the stock speakers. Recommended.

Pros: Cost and good sound

Great Speakers for my 2015 Jeep Wrangler Unlimited

Written By Rick, Toledo,OH on Tuesday, March 17, 2015

Crutchfield Customer Review (What's this?)

Just installed 2 of these kickers in my overhead soundbar. There is a definite difference in the clarity of sound w/ just the two. Can only imagine what 2 more will do in the dash along w/ a compact amp! I utilized the included bracket with the 4 silver screw bolts on each open end to secure speaker to bracket. This was the only possible way to attach w/o trimming the bracket.

Pros: Crisp, clear sound w/I distortion.

Good Inexpensive Upgrade

Written By Marc, California on Tuesday, March 17, 2015

Crutchfield Customer Review (What's this?)

Installed these speakers in the back doors of a 2010 Suburban. Super Easy! It probably took me about 20 minutes to put in each speaker. This was my first time to install car speakers and the documentation provided by Crutchfield was all I needed. Crutchfield also supplied the necessary mounting brackets (Scosche SAGMHR-634) and speaker wiring harnesses (Metra 72-4568) which made everything work without a hitch. They installed behind the existing factory grills so no modification was necessary. They sound great - especially compared to factory.

Pros: Excellent sound clarity. A real upgrade from the factory speakers. Solid, crisp bass response without distortion.

Crutchfield Customer Review (What's this?)

These were the recommendation from the Crutchfield specialist. Tons of knowledge. Really helped to dial in for my 2012 Ram quad cab. There was a depth issue with the front door speakers that she dealt with immediately and sent all the harnesses, fittings and instructions. Sound is amazing. Plus the free shipping that arrived really fast was another perk. Thanks and will return for business.

Pros: Perfect fit in the front doors that had a shallower area then the back doors.

kicker 40CS654 6-1/2" speakers

Written By Anonymous, Charlottesville va on Sunday, March 08, 2015

These speakers are definitely a great deal and sound great. I can't wait to get a new head unit instead and my amp hooked up to hear what they sound like then cause right now all I have is a factory am/fm radio.

Pros: Easy to install and look great.

Perfect replacement

Crutchfield Customer Review (What's this?)

I bought these new kickers to replace my blown out factory speakers in my 2008 G6. The speakers sound great and were very easy to install. The mounting brackets that came with them are also very satisfying as such they fit perfectly. The sound quality is great and it adds a little bit of bass also. If you're looking for new speakers without replacing anything else, these are perfect for you.

1997 GMC Suburban

Written By Big G, California on Wednesday, February 25, 2015

Crutchfield Customer Review (What's this?)

I selected the 6.5" version as the front and rear door replacements for the stock speakers in my 1997 GMC Suburban (with factory premium 8 speaker system) and I'm totally satisfied with fit, ease of installation and sound quality. The rears did not require the included adapter plate, just the 6 long screws and hanger clips (3 per speaker) that are also included free with the free installation kit. The fronts fit perfectly as well with the included adapter plate which, once you clip off the unused tabs, resembles and attaches just like the factory install plate that is permanently affixed to the factory speaker without need of any of the included free hardware. With the speakers, the free location specific installation hardware and wiring harnesses and the vehicle specific installation instructions this was a great value! And I cannot forget to mention the shipping speed, ease of use of the website and helpfulness of the Crutchfield team!! I will be doing business again with them in the very near future!!

Pros: Price, quality, sound, free location specific hardware and wiring harness, shipping speed, ease of use of the website and the great (and free) customer tech support!!

Cons: The vehicle specific instructions are vague and leave a bit to be desired but with a little mechanical/electrical experience and common sense the installation was actually very straight forward. But if you're in trouble, the Crutchfield team is always a (free) phone call away with all the answers!!!

Way better than stock!!!

Written By Kevin O., OKC on Monday, February 23, 2015

Crutchfield Customer Review (What's this?)

2011 silverado front door. Installation was straight forward. I watched several onlinee videos so I had a pretty good idea of what I was getting into before hand. Crutchfield even emailed detailed instructions but I never had to reference them. After separating the door panels I left the door release cable attached and just rotated the panel out of the way to access the speakers. You need a 10mm socket with an extension to remove the panel and 9/32 to remove the speaker. The wire harness provided for free plugged right into my stock harness and the speakers fit right into the brackets provided for free as well. I chose not to buy the boom mats and can still tell a noticeable sound difference from stock. Clear crisp vocals with moderate bass and no rattling. Everything arrived super fast after ordering and was packaged professionally. Crutchfield can't be beat.

Pros: Crisp sound, great product for price

Cons: None that I can think of

2011 honda pilot install

Written By Edwin, 11367 on Saturday, February 21, 2015

Crutchfield Customer Review (What's this?)

I installed these on all 4 doors of a 2011 honda pilot. I first had them running without an aftermarket amp and wasnt too pleased. Although they sounded decent they felt less powerful than the factory speakers. After using them for about 2 weeks without an aftermarket amp, I installed a alpine f300 amp with them and it makes a huge difference! They sound way louder and produce a cleaner sound. These speakers are good with an amp on a honda pilot but not really worth it if you only connect them to the factory system.

Pros: Price Good with aftermarket amp Can handle a lot of power

Cons: Not much of an upgrade to a factory system

For the price, can't be beat

Written By l337sponge, los angeles, CA on Saturday, February 21, 2015

Crutchfield Customer Review (What's this?)

Installed into a 2011 mk6 VW Jetta TDI, with stock head unit. i ordered 2 sets to replace my front and rear speakers. Kit came with Scosche SAC-656 speaker mounting brackets and wiring harnesses.

All my stock speakers were blown and I needed replacement, can't stand driving for hours without music. These had high reviews and crutchfield hooked it up with the mounting brackets and harnesses. The brackets are not needed, the speakers mounting slots line up with the original holes, you do however need the mounting hardware that comes with the bracket. I put rubber foam weatherseal on the back of the speaker to eliminate vibrations against the door and ensure the door is properly sealed. The wiring harness dongles are awesome as it eliminates the need to cut and splice... making a return to stock if needed very simple.

The speakers sound amazing, I honestly wasn't expecting them to sound as crisp or produce as much bass as they do. Don't misunderstand, you won't be winning any competitions and if you want heavy bass these will leave you wanting more. They produce enough bass to make the door panel rattle a bit and lightly vibrate the rear view mirror, remember they are only 6 1/2" speakers. The highs and mids though are INCREDIBLY crisp, on par with speakers almost twice the price. Couldn't be happier with my purchase, highly recommended for a budget speakers, I don't think anything else in this price range can compete.

Pros: sound is incredibly crisp speakers look and feel very well made

Cons: none
