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. And the refined, black grilles included with the package allow you to do a custom installation that'll knock people out.

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 41KSC6747'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 6-3/4" 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.

kickers in 2013 RAV4

Anonymous from Florence, KY on 11/21/2016

Crutchfield Customer Review (What's this?)

Installed these in the front doors of my 2013 RAV4. Running them off of a Pioneer 2800BS (can't remember full model #) head unit. They sound very good much better than OEM speakers. They do hit some of the lower frequencies which some of the other reviews said they wouldn't. After hearing them in the front doors, I ordered the same speakers for the rear doors. An amp would make them sound even better but I'm ok with head unit power for now. Also, the Metra speaker mount adapters for the RAV4 must be modified to fit these speakers (or any speaker) and the door. Specifically, the tabs on the inner circumference must be cut off, and 3 of the tabs on the outer circumference must be cut off. It will make a mess of little shards of plastic. I recommend a coping saw.

Pros: Sound very good,clear, punchy mid bass, able to play the lower bass frequencies also. Thin design which allows fitting them in the RAV4.

Cons: None really, other than an amp would make them sound better. Not the fault of the speaker.

Augustus from Pelham, AL on 8/23/2016

2008 Toyota Prius
Crutchfield Customer Review (What's this?)

These speakers were easy to install into my 2008 Prius (Without JBL) with the Crutchfield-provided plastic ring adapters. The speakers themselves appear to be of good quality and durable, though I'm far from an expert. They are currently being driven off of the absolutely terrible factory head unit (5-10 watts RMS?) but sound great at all of the volumes I listen at. I know they would sound much better off of an aftermarket head unit, or even better, an amp. One thing for other Prius owners to note : The factory stock tweeter has a built in crossover that BLOCKS the upper mid range from being passed on to the woofer! You can solve this by either purchasing the stock JBL REAR tweeters, which will plug right in, and pass on the full range signal to the woofer, or you can hack up your speaker wiring to bypass the stock crossover that is built into the tweeter. I highly recommend replacing the factory tweeters with something better though, even the stock JBL rear tweeters aren't that great. Don't forget to use a crossover.

Pros: Good quality, easy to install, sounds good.

Cons: Don't install themselves.

Jared on 6/17/2016

2015 Jeep Grand Cherokee

I ordered these from Crutchfield and they arrived about 2 days later. Amazing service. I installed these in the rear door, along with the Kicker 41KSC694 up front, and couldn't be happier. The 6x9s fit without modification but these required drilling three holes in the stock speaker mount. I'm running everything off the stock head unit (for now) and am really impressed with the sound quality. I cranked the volume just to see how they would hold out and they didn't even flinch. Zero distortion and great sound. I'd also like to give the Crutchfield advisors a shout out. I sent an email at 10pm EST with questions about my install and received a response at 1015pm. Now that's service!

Pros: Easy installation. Great sound quality. Zero distortion.

Cons: I had to drill three holes in the stock mount to get these to fit. To be fair, the Crutchfield advisors said that would be required. I just wish a bracket was available instead of drilling. No biggie.

The improve,net over the factory speakers is night and day. Having said that, I'm still trying to dial my system in completely, but they feel lacking just a little in the mid range. I don't know, I'm still fooling around with it all. But they went in my truck super easy.

Pros: Cheap Good bass for littles

Cons: Mid range only ok

Upgraded from my factory stock speakers. Outstanding performance. Clean, crisp highs and mids. Not much bass tho. Sub woofer will be the next upgrade. A big thank you to CJ in the customer service department. I called and told him my exact situation and asked his advice. He answered every question without hesitation. Very knowledgeable about all of Crutchfield's products. As you all know, good customer service is extremely difficult to find these days. Overall, a great experience all around.

They sound great! Nice smooth high's, and surprisingly good lows for a small speaker. Running them with a Kenwood KDC X700 putting out 22 Watts RMS and they are plenty loud enough with the deck power. I am glad I bought these.

Front replacement speakers for 2008 Trailblazer

mikewh328 from New Jersey on 10/28/2015

2008 Chevrolet TrailBlazer
Crutchfield Customer Review (What's this?)

It was suggested to me to replace my original, factory-installed speakers with these. I watched a couple of youTube "how to" videos on replacing these speakers, including my rear speakers, but one thing the videos and also the instructions don't tell you (but I WILL) is that to make sure you have a dremel-tool handy. You will be using a cutting-disc to remove some of the plastic from the speaker-casing that houses the original speakers in order to fit in your new speakers. I believe you would be doing this for ANY kind of replacement speakers since the original speakers are more "square-shaped", while all the new speakers are more "round-shaped." Once I figured I could use a dremel and cut away some of the plastic to get the new speakers to sit firmly within the casing, it was fairly easy after that to mount these. Also, I didn't know I had a separate speaker AND tweeter in each of my two front doors - I left the tweeters where they were, I just cut any wiring away from them, since there was no point in removing these (I'd never use them, no one would see them, and cutting them out would have been more plastic shavings all over me.) As I mentioned on a previous review, I probably could have just as easily used a slotted-screwdriver to pop out the door panels rather than being charged the added dollars for a panel-removing tool. Certainly though, if you have never removed a door panel from it's plastic clips before, then having this tool is a good idea. You can share it.

Pros: Price, value, sound (with a few adjustments to your bass and tremble settings if you're using a factory installed stereo, like I am.)

Cons: This is probably going to be the same for ANY speaker you put in your front door(s): you will be doing some cutting of the speaker casing inside the doors which presently is housing the original speakers and tweeters. If you want to get away from this, then spend the obscene amount of money for exact factory replacements, which will surely be a disappointment in sound and quality, but will be a breeze to replace. Take your pick!

Does not fit Toyota Highlander

Greg from California on 10/15/2015

2006 Toyota Highlander
Crutchfield Customer Review (What's this?)

This is a warning about the fit of these speakers not the speakers themselves. On the advice of Crutchfield (claiming to be experts) ordered these speakers. I had to lookup online how to take the door panel off because their vehicle specific instructions were generic and vague. Once I finally got the door panel off I removed the old speakers and cut the wires per Crutchfield's instructions only to find out that the speaker would not fit. I was very upset because I spent a lot of time and effort to get to this point only to have it not fit where it should. I called Crutchfield and let the experts know that these speakers did not fit and their advice was to use washers to hold it in place. I let the person on the phone know that only two holes would line up and that would be fine. That is your expert advice only use half the mounting holes and go buy washers! I don't know about you but I don't like a speaker that rattles in its mount anytime anything is played. This has been a terrible experience and I am going to tack the bracket to a local speaker shop where I can get something that fits which is what I should have done in the first place!


Cons: For a company that prides itself on service I am extremely disappointed!

Kicker reto fit

HOBIE from Florida on 9/26/2015

Crutchfield Customer Review (What's this?)

These speakers provided a substantial increase in sound quality and bass. My 1973 DeTomaso Pantera has VERY limited room for extensive upgrades. This was the easiest avenue to better sound quality. An improvement would be a installation template and available surround (opening) adapters since the previous door panel hole was irregular great sound improvment and somewhat oversize. HOBIE

Pros: great sound improvement

Cons: only included one connecting cable

Great match for Kia Soul

Brad from Albion, NY on 9/19/2015

2011 Kia Soul
Crutchfield Customer Review (What's this?)

I installed 4 of these in a 2011 base model Soul that had a blown speaker. First the sound. Bass response in this application is very good. I did a side by side bass comparison vs factory, neither seemed louder than the other, however I could hear lower notes in the Kicker. Also the Kicker could handle higher volumes with out the bass distorting. Highs are also good, smooth sounding with no harshness, however if you are used to harsh "in your face" highs of many other car speakers these might seem soft to you. Next some notes about installation. The brackets Cruthfield includes to mount these in the Soul fit very good, both to the vehicle (didn't need to drill any new holes) and to the speakers, but you will need to pick up some machine screws or bolts, washers & nuts to attach the brackets to the vehicle. During my installation I used thin weatherstripping between the bracket and the vehicle and between the bracket and the speaker, to prevent any rattles. I also used weatherstripping on the top flange of the speaker where it meets the door panel, to mimic the factory speaker. Now some info about the Kia Soul. Some of the information Crutchfield has on the Soul doesn't apply to the base model Soul. Base model factory speakers are 4 ohm (not 2 ohm). Currently when selecting speakers to fit "front door", a wiring harness is not available, however the wiring harness that comes with speakers when you select "rear door" location does in fact fit all 4 doors on the base model Soul.

Pros: Good bass, smooth highs, nice sounding speaker. Glad this came in a 6 3/4 size.


Great speakers

jammin969 from Alexandria, VA on 9/10/2015

2015 Hyundai Accent
Crutchfield Customer Review (What's this?)

I am very impressed with these speakers so far. I am running 1000w Soundstream (4-channel x 90w @ 4 ohms) and 350w Sound Ordnance (monoblock, 175w @ 4 ohms) amps off the factory head utilizing line output converters to turn speaker outputs into RCAl inputs for amps. One 12" Kicker sub in a ported bandpass box, and then these and the 5-1/2" version for the 4 interior speakers. These speakers are very clear and crisp sounding even when you turn up the volume and add a little bass. Tested it out with some Crystal Method as they have some serious low, dragging bass on some of their songs that the old system couldn't handle and washed out the rest of the song, but with these you can still hear the highs even when it thumps. I had no problems with installing utilizing the brackets and instructions sent by Crutchfield. I wish they would have included how to route new speaker wire to them but since I bought the amp kit elsewhere I guess that would have been getting greedy =P

Pros: -good clarity throughout range -excellent bass if you power them properly

Cons: -nothing so far

Great Bass and crisp Treble

Big Lim from New York on 8/1/2015

2008 Chevrolet Tahoe
Crutchfield Customer Review (What's this?)

Bass is solid. Treble highs are clear and crisp. Mids need a little more but with some adjustments the speakers are very good. These went in a 08 Tahoe to replace factory speakers and they were mounted low on the door. I believe they would have definitely been better mounted higher. Perfect for the rear deck of a car. Installation hard ware was solid, but I had to use different screws then what they came with since they were a little too long.

Pros: Clarity

Cons: Need more power on mid level frequencies.

I installed these in the front doors of my 2015 Tacoma Double Cab. These speakers are great! The highs are clear and the bass is great. I added some GTMAT sound deadener and couldn't be happier. If you decide to go with these, you will not be disappointed.

Pros: They work and sound great!

Cons: They don't fit the back doors, but other than that....NONE.

More Clarity, Less Bass

Joe from Florida on 6/10/2015

2005 Chevrolet Colorado
Crutchfield Customer Review (What's this?)

I used these to replace the stock speakers in my 10-year old Chevy truck, and they're being driven by the stock head unit. The original door speakers (all 4 of them) were rated at 15W RMS; these Kickers, 100W RMS. The Kickers seem to require more 'volume' on the knob to drive them adequately. Compared to the stock speakers, these seem to have less bass, but also have a much higher level of clarity throughout; the result is more 'music' and less 'loud noise'. I've had to readjust the 3-level mixer to max bass, and very low treble to try to get the right balance (according to my ears) for the treble/mids/bass. I'm still fine-tuning it. The end result is, I can hear my music better without a lot of noise and distortion over the 10-year old stock speakers, as one would expect, but part of me wishes there was just a bit more bass.

Pros: Great fitment for the tight space in my doors (window tracks, etc. just behind mounting location). Great mids and highs.

Cons: Wish it had more bass.

Crutchfield Customer Review (What's this?)

With this install price was definitely a factor. And I don't ever like to cheap out when it comes to my music. But for my girlfriends 07 Grand Cherokee I stuck to a "budget build". And I am not sorry about that. The 63/4 is the same size as a factory rear door speaker just different mounting holes and the sound the comes from it tops the others I've heard in the price range. Good clarity, no distortion at high volume, and they are not out driven by the subs. Would deffinately buy these for another install.

2002 GMC Sierra 1500
Crutchfield Customer Review (What's this?)

Installed these in front doors of 2002 Sierra running on Kenwood x998 head unit power only. Also installed using XTC foam baffle (nice for protection, not for bass response). Sound is clear and stays clear with increased volume. For reasonable bass response, I cut away 50% or so of the foam baffle. The speaker does appear to like volume. I can imagine using a 100w external amp would be quite impressive. Materials seem of quality. Pulling them out of the box, they don't "look" like they'd make a lot of volume, I suppose due to the shallow mounting depth, but they get loud for sure. Overall happy with and would make recommendation considering the price point.

Pros: clean sound, nice volume without significant breakup on HU power only.

2012 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

These speakers are appropriately named. They definitely provide the Kick in the rear of my 2011 Silverado. Fit was perfect with the wire/door adapter kits provided. You need to use the break out tab option with the door inserts. I think I will go ahead and put some in the front as well even though these originals haven't gone out (yet).

Pros: Highs/lows are proportionate and to my liking. These produce more boom that the original speakers could and much clearer. Just right.

Cons: Now I need to chase a new bass induced rattle out of the truck-maybe use some velcro padding in the lock areas.


M from NY on 3/12/2015

Ok ever notice how reviews are so biast and never end up correct? Not anymore.These speakers are amazing. The even blend of high,mid,low freq is perfect. They get louder than every other speaker I tired in this new car and had way way more bass. Do not let the picture fool you they hit very hard and clean. its almost unreal how much volume bass and clarity they have. The are better than most mid range component sets Ive had. I know that sounds crazy but its so true!!! Trust a stranger and buy these they have everything you need plus easy to install a million holes for different cars and shallow!!!! Im telling you these rock in every aspect and will blow you away. Better than last 2 model infinity kappas, every level of polk, rockford power series, jbl, pioneer, mb quart, jl. Once again trust a stranger you wont regret it. Stop looking at more expensive and component systems and get these!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I replaced the speakerd in my 2014 tundra with these. I lost a lot of low end bass until I I stalled the foam surrounds. The speakers sound 10x better than the factory ones. If you give them the suggested 100 watts rms they play louder than any sane person could stand!

Pros: It's a kicker! Plays loud crisp and clear

Cons: Low end suffered

DanO from Minot, ND on 2/23/2015

2006 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

Installed these in my son's 2006 Chevy Silverado Crew Cab truck to replace stock speakers that weren't working since we bought the truck. Didn't go too bad. Had to drill new holes for the front and used supplied screws & gm wiring harness. Rear speakers were glued in so we had to pry them out along with a fiberglass plate, but the four existing holes matched up with the new speakers so no new holes needed to be drilled for them. Sound doesn't seem to be anything better than a stock speaker though. He runs an aftermarket head with no amp.

Pros: Fit existing openings with only having to drill some new pilot holes to mount the front. Wiring harness was easy, so no splicing of wire.

Cons: Sound is just average to me. Was expecting more.

2005 Chevrolet TrailBlazer
Crutchfield Customer Review (What's this?)

I installed these speakers in the front doors of my 2005 Trailblazer about a week ago and so far I'm really impressed with them. The high and mid range are very clear, but I was especially surprised with the lows. I listen to anything ranging from heavy metal to blues, but mostly hang around in the hard rock genre. With most speakers I've listened to, this type of music sounded extremely garbled, especially at high volumes. Like the other ranges for the Kicker 41KSC674, the bass is exceptional, even when I crank it up! My only gripe is that they did not fit as specified on my particular vehicle. I was informed about removing some locating tabs on the bracket, but even then I could not get the speakers in correctly. Needless to say, my brackets still function, but they do not look pretty at all. Thankfully they are hidden behind the panel anyway.

Pros: Great sound overall. Love the bass.

Cons: Had to modify the bracket for my vehicle, even though it indicated it would fit.

Crutchfield Customer Review (What's this?)

First off here is what i ordered and compared, polk db651, polkdxi651 ,kicker cs674, alpine spr-60, mb quart onx 6.5. the only speaker that was even close to these in overall sound was the polkdb. these kickers are insane. listen dont let their puny size fool you. look at those alpines they are beasts and were trash. best part is these kickers sound amazing amplified or not they have everything you need, bass bass and mose bass, volume nice and loud louder than my 95db infinity kappas, and smooth clear highs. theres not one bad thing to say at all. i am extremely picky. these blew away everything. they are clean and clear as home audio and provide so much bass my doors rattle and they are sound deadened on both side this inclused the door panel. im telling you these are perfect and i wasnt a kicker fan. these are worth double the cost. everything is even and blended, the high and volume level keep up with the bass which is what makes them so great. so honestly get these you will not regret it I Promise.

Pros: everything!

Cons: None!

Easy Peasy install - silverado

Jimmy's from Orange County California on 10/2/2014

Crutchfield Customer Review (What's this?)

My 2002 chevy silverado works hard and for some time the factory speakers were toast. Called the specialist at Crutchfield and told him what I wanted - clean sound and simple install. He recommended kickers and it sounds awesome. For those of you out there with a silverado - it is super easy. I would have hated to pay someone to do this - I went slow and it took me like just unber an hour.

Pros: Clean sound simple install and great directions - thanks crutchfield . Get the connectors - they are awesome and solid

Cons: Should have done this three years ago

Great Sound

Crutchfield Customer Review (What's this?)

These speakers are loud and clean. I am only running these speakers off a Kenwood stereo, so I only pushing 20 RMS. The speakers are rated to perform at 50 RMS. I am curious to see the clarity of these speakers on a 4 channel amp.

Pros: Easy Install, Have yet to blow them, durable.

Cons: none so far.

Great sound and durable

Chris B from San Antonio, TX on 8/19/2014

Crutchfield Customer Review (What's this?)

Great sound and very well made. The speakers offer a reasonable amount of base for a speaker of their size. They are perfect for doors and offer a high level of weather resistance. Everyone has seen paper door speakers rot out after heat and moisture have their way.

Pros: Good price. Great durability. Quality construction.


Kicker KSC67 for 2008 GMC Sierra crew cab

Ric from Seattle, WA on 6/16/2014

2008 GMC Sierra
Crutchfield Customer Review (What's this?)

First Crutchfield experience - Excellent support and the Kicker brand speakers are great. Far exceeded the local Car Toys who told me to go away and just buy a stock speaker. Right side door speakers quite working in my 2008 GMC crew cab. Installed four Kicker KSC67 and left the stock tweeters connected in the pillars for now. Sounds great. Bought the Bojo trim tool kit also which made install a snap. Found a You-Tube that helped along with the instructions CF gives you. 15 mins per door start to finish once you figure out how to remove the panels, if you pre-assemble the speakers to the adapters.

Pros: Support - Quality Products.

Cons: The ETC baffels are not needed - complicate the install - don't clear the window travel. CF refunded the $18 price of the baffels whenI i told them that about the recommended baffels.

It is ok not really much bass at all i could use more power i have the stock factory head unit. [ Steve  Aug 27, 2015 ]
It is very good compared to a factory system. I would put it a little above a factory Bose system. That said if you want really heavy bass these might not be your best buy. [ Peter  Aug 27, 2015 ]
Yes it's good. [ patrick  Aug 26, 2015 ]
I use them strictly as Sub Woofers in my car - and yes - Bass is good for this size speaker. [ Carl P.  Aug 25, 2015 ]
I turned off the bass within those speakers and allow my subs to take control. The bass was decent, however I was running it 25 rms (headunit). If you run them through an amp you might get better results. The speakers do have a clean sound. [ christopher  Aug 25, 2015 ]
The bass is ok. [ jkonen  Aug 25, 2015 ]
Not really... There is a sharp drop off below 80hz. They do play clear at higher volumes [ FRANK  Aug 25, 2015 ]
its better than stock paper speakers. its not gonna rattle ur windows if thats what ur looking for. [ reid  Aug 25, 2015 ]
For the size of speaker, yes. [ Kent  Aug 25, 2015 ]
For the size yes but for maximum performance use a amp. These speakers are very nice for the price, hope my answer helped [ Ali  Aug 25, 2015 ]
There is a basic in line capacitor for the tweeter. I am not sure of the value, but I would guess its around 5khz. It is "jumped" off the woofer input terminals, meaning you dont have to do anything special to hook it up. The woofer has no crossover. It will play whatever signal you send it. Hope this helps. [ BRANDON J  Jan 27, 2015 ]
No [ Brian  Jan 27, 2015 ]
Yes, but they aren't as good as buying a separate crossover and mounting the sub and tweeters in different locations. [ austin  Jan 27, 2015 ]
