Kicker 40CS674

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 40CS674 speaker set provides low-end from a tough 6-3/4" 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 6-3/4" 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: 1-7/8"
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why replace your factory 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?)

Overall the install was a great experience. I can remember when I was younger, installing speakers and radios was an nightmare. All the new helpful brackets and wiring harnesses made things a lot more pleasant. The only beef I have is one pair of my speaker adaptors were broken, but with all that night mare experience I have accumulated over the rough years, I just glued them bad boys back together and put them in any way. One day I might get a tuner to go with the new speakers and maybe I might even get an amp to push a little more bass. but for now I am pleased with everything accept the brackets being broken. Probably happened during shipping I'm sure. Just make sure you check all your components for damage before you begin your install.

Pros: Easy as pie install

Cons: Damaged goods

Kicker Speakers that Rock!

I purchased these to replace the factory speakers in my ride. These new speakers will crank out great sound down low or at maximum volume. I was overdue for a new sound system and these fit right in at a very reasonable price point!

Crutchfield Customer Review (What's this?)

The speakers were very easy to install and they sound great

Pros: all the holes line up and the wiring indicators for positive and negative are marked

Cons: Had to remove the wiring plug in from the original speakers and solder them to the leads to the new speakers. the problem was that the wiring plug did not have the positive and negative marked so you have to go to the wiring in the car and figure out which one is which

Crutchfield Customer Review (What's this?)

all the products were great. The front adapters fit ok when you used the Boom Mat Speaker Baffles, otherwise they would not have been as tight to the trim. The 6 3/4 did not fit in the original holes, I had to drill some extras. The rears speakers didn't have adapters. I cut out the old speaker and used the original Gm bracket. They fit to tight with the Boom Mats. But with a sharp knife and some cutting and drilling of new holes they fit pretty good. If you do this , check YouTube for hints and keep some 1/2 foam door gasket stuff around. All in all, I am very happy the way these Kickers have made my original radio sound. I would do it again.

Pros: great sound for the money

Cons: did not fit as easy as they made it sound, but not to bad.

Great sound, great price, perfect final product for complete new stereo install in my vehicle.

Pros: Sound, price, Kicker Quality & Crutchfield Support

Cons: Mounting brackets supplied by Crutchfield had to be slightly modified to align with the mounting holes in my vehicle and to route the speaker wire. Simple to do with a drill and a round file.

Great Speakers

Written By StephenH, California on Friday, November 06, 2015

Crutchfield Customer Review (What's this?)

I bought these speakers to replace my factory door speakers which where JBLs. These sound just as good to my ears...with quite a bit of bass and clear and crisp highs. Two things really made this purchase great: 1) Crutchfield knew which adapter I needed for my car and sent that free with the speakers, and 2) they e-mailed installation instructions to me soon after my purchase. It was nice to be able to plan ahead and know what I needed to do and what tools I needed for removal and re-installation of my door panels.

Pros: - Hard to beat the price for the sound quality - Installation instructions and adaptors where sent free-of-charge

Cons: - None

Good Deal!

Written By Anonymous, California on Friday, November 06, 2015

Crutchfield Customer Review (What's this?)

Noticed an improvement over OEM miata speakers. My OEM, front speakers, were still working. However, I needed a minor speaker upgrade. The kicker's did the job, it's much louder with clearer sound. BTW, the Kicker's were driven by my Head unit an AMP would surely maximize it's true potential.

Pros: Plenty of power for everyday listening, but don't expect any decent bass. You need a sub & AMP for that.

Cons: I had to drill 1 hole on each speaker to avoid drilling the door. No big deal it was worth it.

Sounds great!

Nice Upgrade

Written By Paul, New York on Tuesday, October 13, 2015

Crutchfield Customer Review (What's this?)

Used these to change out rattling stock speakers in the rear deck of my 1997 Mercedes E320. The fit was perfect but the instructions missed a minor detail about how to remove the back head rests - they were saying push them out with lots of force but the correct way is to pull the black tab to the front of the vehicle and it come out like jelly (after almost giving up 'cause that thing couldn't come out even with a crow bar). The sound quality is a definite upgrade. This added to the overall component system makes me feel good. Good top end clarity. Speaker technology has really developed over the past few decades. Now I need some low volume bass kick so I'll try a compact subwoofer and figure out where it will fit. Crutchfield is very good with customer service. Cutting edge company. Tech folks are knowledgeable and shipping is fast. Overall good experience.

Pros: Good clarity and top to mid quality

Cons: Nothing yet

These speakers were exactly as advertised, and easy to install. Perfect for changing out the factory speakers in a 99 Chevy Tahoe.

Pros: Easy to read instructions, easy to install.

Cons: Nothing.

Very clean sound!

Written By David D, Florida on Saturday, September 26, 2015

Crutchfield Customer Review (What's this?)

One of my rear speakers broke in my 2012 Elantra and I knew the best place to go was Using the fit guide and reviews, I selected the Kickers as a replacement set. The installation presented some challenges, as the installation instructions didn't state clearly the I would have to modify the speaker brackets; so I would encourage Crutchfield to consider updating its instructions.

Once I got the speakers installed and fired up Rush's "Permanent Waves", I could tell the speakers were well worth the effort! Bass is much stronger and clean, and overall sound is significantly better than the factory speakers. My only problem now is that I guess I will have to replace the front set. ;-)

Pros: Strong bass. Crutchfield tech support.

Cons: Installation instructions could have been a little more clear. I had to call Crutchfield support twice to seek clarification.

Used these to replace the door speakers in my 91 Miata. Very easy installation only required minor modification (one hole). I don't do any critical listening in my car so I'm not going to demand much from the sound system. . these do the job well. The install kit with the wiring harness was very helpful.

Pros: Easy install. Good sound.

Cons: None
