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.

Nice Speakers

Written By Josh, Ohio on Thursday, September 03, 2015

Nice speakers for the money. Factory speakers were junk. These were a nice upgrade, while I am still using factory head unit.

Pros: Good sound with factory head unit.

Cons: None

Clear sound, less bass

Written By SleeperZ, Burbank, CA on Sunday, August 23, 2015

Crutchfield Customer Review (What's this?)

The speakers have very clean and loud sound, much better than the stock speakers. The bass is much weaker than the stock speakers, but with a small amp in sure that can be fixed. I was hoping for more bass from a company that started with subwoofers.

Pros: Very clear sound, louder than stock speakers

Cons: Even with the bass turned up on the equalizer they are still lacking in bass. Might be fixed with an amp, but that is additional $$

Vitara 2001 new speakers

Caribbean Jimmy

Very good speaker with good bass. Fit exactly in the Suzuki Vitara 2001 front doors (of 4 doors). The connectors were somewhat difficult to attach to the speaker harness. I expand the harness female connector by the fear of bent the speaker male connector. The sound, great. These speaker replace two non-working original. Now I have two doors that rumble.

Pros: Clear sound, with strong bass and an exact fit.

Cons: Non really!

Crutchfield Customer Review (What's this?)

I was looking to improve the sound of my factory stereo in my company van and can't make major changes. A Crutchfield member recommended the Kickers. With just a slight pull back of the door panel I was able to swap them out. The sound great even-though I didn't add an Amp.

Pros: Fit right in and sound great.

Cons: None.

Kicker 40CS674

Written By Zach R, Colorado on Sunday, June 28, 2015

Crutchfield Customer Review (What's this?)

These speakers are quite good for the price. They have accurate highs and lows and even though it is not a component system, the crossover doesn't seem to be too bad. That being said, you will need an amplifier in order to truly hear and feel what these speakers can do. For general listening purposes, hooking these up to a stock radio is a good choice, but their are cheaper options than these speakers. Their value truly lies in how much you can push them and their potential for upgrade ability. I am currently only powering these speakers with a Kenwood receiver that gives each speaker 22 watts RMS, so it begins to approach the optimal power of the speakers, but it really needs more for the mid-bass notes. These speakers look good, sound good, and have tons of room for a power upgrade.

Pros: Clean sound Allows for powering up your system Looks good Good price

Cons: A somewhat low sensitivity Not as efficient as other speakers around the same price Needs an amplifier to truly wake up the system (this is only because I love bass and is not a direct fault of the speakers)

Great factory replacements!

Written By Dave M, Erie, Pennsylvania on Thursday, June 18, 2015

Crutchfield Customer Review (What's this?)

On the recommendation of a crutchfield adviser, I replaced all of the door speakers with these kicker 40CS674. I kept the factory stereo and have no amp on these and they sound beautiful! The improvement over stock is well worth the price of these kickers. The bass for my system is handled by 2 - JL Audio 10W0v3-4 Subs n a Sound Ordnance Bass Bunker Sealed dual 10" subwoofer enclosure powered by the Rockford Fosgate R500X1D Prime Series mono subwoofer amplifier. For a system that keeps the factory stereo, I think it sounds amazing.

Pros: Nice mids and highs Very efficient Great factory speaker upgrade

Cons: None

Great speakers for the price. Great sound quality

Give a good kicking

Written By RayMan, Oregon on Sunday, June 14, 2015

Crutchfield Customer Review (What's this?)

When looking for speakers, pay attention to the Frequency Response range listed in the SPECIFICATIONS tab. This one goes all the way down to 45 Hertz. The lower the low end of the range is, the more bass. Don't expect massive bass with these of course, they're not subs. Paired with my Alpine HU and the Alpine Power Pack, it works really well for my taste. (And it really is a matter of taste with sound right. Mine does not involve rattling license plates or dimming headlights that then require a capacitor between your battery and the amps and the...ahh, reminiscing my high school years.)

Pros: Good fidelity for the price. Compared to the Alpine SPR-60's (which I had in my truck first), I preferred these Kickers more again due to the lower end frequency range.

Cons: Be aware that if you specifically have a 1998 4Runner, the screw holes on these speakers won't align with the screw holes on the factory speaker assembly where this attaches to. This is also the case with the SPR-60's so it's not a speaker issue but more the age of the vehicle. They can't accomodate all the radius measurements across all years of vehicles so it's a matter of demand and supply. No prob tho, I used screws with a wide head to hold them firm.

Overall the speakers sound great. If your looking for stock replacement speakers this is it. Watching Utube videos on removing the door panel is the way to go and installing the new speakers. Take your time on doing the work and it will turn out very well.

Written By FTC(SS) Ret, Washington on Monday, May 25, 2015

Crutchfield Customer Review (What's this?)

I used the Kicker 40CS Series 6.75" and 4X6" to replace the factory speakers in my wife's '02 Chevy 2500HD. After some considerable Dynamat work in the doors and dash, they went into the factory holes without issue. Along with a Pioneer AVH-X7700BT and a Kicker 8" Hideaway Subwoofer, This truck really rocks!!! Crutchfield made it super easy to plug 'n' play those speakers!!! Thanks!

Pros: Clean sound, punchy mids and crisp highs

Cons: Very touchy low end freq range, lows are a little distorted, easily mitigated with a crossover.

Bought some JBL 6.75 that were terrible and swapped to the CS Kickers with no regrets. I have never been a Kicker fan, but I really do like the CS series. My kenwood Excelon pushes these speakers without distortion or clipping unlike the JBL's. I bought these for temporary until I found an upgraded alternator for my Kia Sephia with the intention of running an active JL Audio C5 component setup to complete my two JL 10W3v3s.

Pros: Crisp highs, accurate mid bass. Can be ran with low RMS without clipping or distortion.

Cons: For the cost, cons are N/A

My girlfriend's 1992 Miata needed some new speakers to replace the blown ones. I selected the Kicker 40CS674 as Crutchfield shows no brackets required. Super easy install with the provided Mastersheet. I did have to drill holes to mount, and I'm not that mechanically inclined but finish the install of the two door speakers in about 30 minutes.

Got 2 sets to replace all the speakers in my chevy colorado. As far as the speakers go, sound quality is very good. only downside to these was the mounting screws that come with it. they are just cheap crap. after 1 speaker went in the second i had trouble with the screws threads just smashing while trying to screw in. I just went to the hardware store and bought some 1" #8 self tapping sheet metal screws. had to go back to the first speaker 2 weeks after install and swap out the original screws for the better ones i bought as it began to loosen and rattle.

Pros: sound quality is great

Facts and what you need to know.

Written By Charlie, New York on Friday, January 02, 2015

Ok So everyone hearts different things with speakers what you hear maybe someone else hears something different. So I going to go with only facts and explaine them for you to help you truly know and understand these. So I bought a bunch of speakers and compared them all and bottom line no other speaker produced the bass these did not even my monster Jbl p660c components amped and not amped these blew all other away with bass. Now instead of just saying these are great and loud I'll get into detail about them, First off a fact no matter what you listen to and weather your doors are deadened(highly recommend) or not you will get bass out of these. That's their biggest plus that's what stands out the most. Next is their tweeter. It's loud crisp sharp and pretty accurate. Also because kicker made these for stock replacements the tweeter is lower inside the speaker which actually helps imaging because the tweeter high actually get spread and pushed by the cone if you will and makes for a fuller louder sound. Next fact is the ease of install I mean so easy these will most likely fit into 5 1/4 openings that's how shallow and thin they are. (Do not let their size fool you the look puny but sound full and loud) one of my favorite this is the basket it has so many different shapes and opening for screws to accommodate any car. That's whatt kicker did great with these is make them insanely easy to install for any car. These only have one flaw, no crossovers distort at high volumes.

Pros: BASS Crisp tight high end LOUD( put polk db6501 to shame) Insanely easy to install easier than any other speaker

Cons: Distortion at high volume no crossovers to clean sound only drawback.

Slight Modifaction Was Needed

Written By Glen, Rowlett, TX on Monday, December 29, 2014

Crutchfield Customer Review (What's this?)

The speakers sound great and fairly easy to install. Installed the speakers (X 4) in a 2007 Chevy Silverado crew cab, replacing the factory system.

Pros: They were delivered in a couple of days even before I received the tracking information, this was during the Christmas rush.

Cons: The mounting clips didn't have any instructions, one of them even broke very easily so we used self-taping screws for the front door speakers but we were able to use the factory screws and mounting holes for the rear door speakers. The rear door speakers were .0825" too big (diameter) so we had to use a die grinder to remove a little material from the factory mounting housing and the they slid right in.

Happy Dad

Written By DusterP94, Middle of the IN/OH line on Saturday, December 27, 2014

Crutchfield Customer Review (What's this?)

I bought these for my Dad to replace blown factory units. I just got a call from him about him installing them. He is not mechanically inclined but wanted to try it. He said it went without a hitch and the included wiring adapters did the trick. He said he's just as happy as could be with the sound. He says it's much better than when his truck was new. (2003 GMC Sierra ext. cab) (Had to drill new fastener holes for these ever so slightly over sized speakers) He said he wished he would have done this long ago. As for my end I'll say that the price was more that competitive when comparing quality products and the free included model specific instructions and installation aids sealed the deal for me. Product arrived quickly, as described, and in perfect condition. I'll be ordering again from Crutchfield for sure.

Pros: Fast shipping. Good Packaging. Competitive Pricing. Included installation Materials. Vehicle Specific Directions.

Cons: Really only 1 very minor issue. Needing to drill new fastener holes for the speaker to mount properly. This is easily done, but it is an added step.
