Our take on the Kicker 41KSC44


The 41KSC44 features a slim design, making it a perfect fit in more cars.

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 with the included black grilles, you can do a custom installation that'll look great.

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 41KSC44'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 performance, starting with the surprisingly full sound of the 4" polypropylene woofer and its powerful magnet. You'll also hear subtle vocal and instrumental details from the silk balanced dome tweeter, giving your music a dimension that factory speakers just can't manage.

Crutchfield Customer Review (What's this?)

The kicker speakers are one of the most amazing speakers that I have came across and knowing that it came from Crutchfield was another amazing sell as well being able to deal with people that are easy to talk to and always easy to understand

Pros: Being able to get product reviews through books and on the internet via emails

Cons: The only thing that I would have to say would be one of the negative would be when I have to return a product I have to pay for the shipping label that would be the only negative that I would have to disagree with especially when they say you get a 60-day money-back guarantee

Great Sound Excellent Price

michael from Aiken, SC on 2/14/2017

2002 Lexus SC430
Crutchfield Customer Review (What's this?)

These speakers was an excellent choice for ear popping clarity, simply amazing sound for the price! Added a set of Kicker 43CSC6934 6x9's to the front doors and the speakers sound amazing together, they complement each other well.

Pros: Clear sound with just the right amout of bass!

Cons: Crutchfield website states that 6x9's don't fit the Lexus SC430 and that wasn't true, the factory speakers are 6x9's and can be replaced with 6x9's. The site also said that the Kicker 41KSC44 had to be modified to fit in the rear and they bolt right in. Site has misinformation on product and vehicle

Crutchfield response on 2/21/2017 Thanks to Michael's review, we're reviewing our fit information for the Lexus SC430. Our fit guide doesn't always show the original sizes from factory sound systems, since they often don't adhere to aftermarket sizing protocol just as this Lexus doesn't. Our guide shows what we've determined can fit from the dimensions we've measured from the test vehicle and the speakers we carry. Even if the measurements are only slightly off, they won't show as a fit. So, we're really glad Michael was able to get these Kicker speakers to work.

Good speakers for the price

Sean from OH on 2/6/2017

1996 Toyota Avalon
Crutchfield Customer Review (What's this?)

Replaced all 4 door woofers in my 96 Toyota Avalon with these and just kept the factory tweeters from the component set that were there. Installation was pretty simple. I just screwed the supplied screws straight into the black plastic enclosures that exist in the doors where it made sense with one small flat washer per screw (not supplied) to make sure all caught some of the tabs on the speakers. 4th screw in front doors is not doing much by the way. These speakers are slightly smaller than the factory speakers FYI. I could have filled or sealed the space in one way or another but was in a rush to get done. Sound does not seem to be affected. Not much experience with 4" speakers but they sound good enough for the price when powered by the factory amplifiers. I have a pair of old 8" Kicker Comp subs in the trunk with a Rockford Fosgate Prime R150X2 bridged to them filling in the bass. I also replaced the failing head unit/6 disc changer with a Sony WX-900BT using the 6 or 7 speakers harness for my car to use the factory amplifiers still. All together sound more than good enough for my secondary "back-up vehicle." Be sure to turn up the high pass filter on your head unit or amp if possible to keep the bass from them.

Pros: Sound good for the price and probably also for 4" speakers.

Cons: Not quite as good as factory speakers once were but are close. (The factory cones and surrounds had turned to dust and chunks.)

great product

Pros: Sounds great, and fits perfectly.

Cons: None!

Clean and strong Mids and Highs!

Sam from Los Angeles, CA on 11/11/2016

1993 Toyota Corolla
Crutchfield Customer Review (What's this?)

Purchased these as replacements for my front door speakers of a 1993 Corolla Wagon. As everyone mentioned, bass is present, but very minimal. These speaker truly shine in the mids and highs. Although smaller than the stock speakers, the sound coming out of these without an amplifier and a 10 year old receiver is amazing! Purhcased the baffels that Crutchfield recommended and it definitely gives it a nice mid bass and does help it put out a little bass. The screws that came with it are on the longside and punched through the rear of the oem speaker bracket, so be careful when screwing them in. Definitely will ordering another set for the rear.

Pros: Speakers will fit in tight Spaces. Clear Mids and Highs. Easy to install.

Cons: Lack of bass would be it's only downside, but fixable with the addition of a sub.

Old Car - New Sounds

Doug from Vermont on 9/20/2016

1989 Saab 900
Crutchfield Customer Review (What's this?)

I recently purchased an old SAAB and trying to bring it back to life. So the speakers were a target. The 27 year old speakers were sort of working and it was impressive that they could. But after dropping in these Kickers the improvement was fantastic. Fitment was not a problem and all material needed was there. Pretty much a straight drop in. So the installation was a snap and the sound superb. Life is good. Now new head unit will complete the transformation.

Pros: Super easy to install and the sounds are really great.

Cons: None

Good Little Speakers

Ben from Omaha, NE on 8/24/2016

2002 Subaru Forester
Crutchfield Customer Review (What's this?)

I have these speakers hooked up to an amp that pushes 60 watts RMS, with a hi-pass filter set at 250 Hz. I'm very happy with the quality of the sound from these little guys; they can get loud without hissing and keep things clean. Don't expect any bass response (they're pretty small units), but the frequencies they do hit they hit well.

Pros: Good quality, clean sound even at high volumes, can handle the power output from my amp

Cons: A bit pricey

Small but Mighty

FelixM from Chico, CA on 8/16/2016

1994 BMW 325I
Crutchfield Customer Review (What's this?)

These small 4" speakers sound great installed in the door panel of my 325i convertible. It produces great mid bass and the highs are decent. Matched with Kicker 40CS54 5.25" in the rear quarter panel and Kicker 10" sub (2 ohm) in a truck box in my trunk. Jensen 600 w 4 ch amp & MTX 500 w mono amp.

Pros: Great fit in tight spots

Cons: High frequencies are just okay. I felt I needed separate tweeters to complete my system.

Sound great !

Crutchfield Customer Review (What's this?)

I replaced my speakers looking for cleaner mids and highs and I was impressed with the clarity of these speakers. These were installed in my front doors with factory component speakers and it made a noticeable difference. No bass but I didn't expect it from a 4" speaker

Pros: Cleaner sound

Cons: None

Bought these to replace the stock rear speakers in my BMW 128i. Not much bass, but didn't expect much from a 4" speaker. Great sound, especially when cranked up a bit! Installation was a breeze. Very pleased with them.

Pros: Easy to install Great sound from such a small speaker

Cons: None

Crutchfield Customer Review (What's this?)

Easy install. I have a bmw 328i. Two of the holes line up. Bend up the tab on one side to seat it flush. Drill a hole for the third screw and use the supplied clips. Screw it in and bump your beat. These are rear deck instructions. Sounds pretty good without an amp in conjunction with my woofer.

Pros: Good sound

Cons: None

1988 Toyota Corolla FX
Crutchfield Customer Review (What's this?)

These were great right out of the box. Easy to mount and connect in my 88 corolla . I am not an audiophile so nothing technical in my review. They work great for what I needed

Pros: They sound great and really fill up the car, I bought 2 pairs for this project. Not disappointed at all.


Great speakers, terrible instructions

Matt292 from Florida on 12/2/2015

2007 GMC Sierra 1500 Classic
Crutchfield Customer Review (What's this?)

The speakers themselves are incredibly clear and well constructed. With the speakers themselves, I had no issue. The installation instructions are deplorable, however...if I had it to do over again, I would have gone with a 4x6" that would have fit no problem, I made the mistake of succumbing to the suggestion of a Crutchfield rep and moving to a 4" wouldn't be so bad if the adapter bracket were made to directly replace the factory speakers, but the universal adapter only allowed me to secure the speaker with two screws on the top or bottom, not even one on top and another on bottom. Ideally they should have a mounting bracket that has the clips like the original equipment.

Pros: Great sound quality, clear and easy to install

Cons: Installation cleanliness wasn't the best, but this isn't a reflection on the speakers themselves, rather with the suggestion from Crutchfield to use a 4" speaker in lieu of a 4x6", which would have fit perfectly. I don't mind drilling new holes, but it needs to allow for 4 screws in each speaker instead of 2. No sense in sending them back now, I've already drilled the holes, so that ship has sailed.

great speakers

great loud speaker audio does not distort and sounds amazing



Surprisingly good sound

JMC from California on 11/16/2015

Crutchfield Customer Review (What's this?)

I purchased these as a replacement for a 4 inch Nakamichi Lexus SC400 door speaker, without expecting the sound to be near as good as with the factory Nakamichi. (Side note is the dealer wanted nearly $400 for the replacement speaker). Because the speaker came in a set of two, I decided to install only the one which was blown. This allowed me to compare the sound of this to the sound of the one in the opposite door ( using the balance control) . Well let's just say, both speakers now sound the same!

Pros: open screw flange allows these to be used as replacements for speakers that are not exactly 4'',as the Lexus speaker housing is 4.125"

Cons: I was going to say, "must be purchased as a pair", but never mind! none so far


Braden M from Kentucky on 10/16/2015

2001 Nissan Frontier
Crutchfield Customer Review (What's this?)

I bought these speakers because my 2001 Nissan Frontier had crappy blown out stock speakers. I bought these not expecting anything extremely fantastic but I after I got them in I was truly blown away.

Pros: Great sound quality Bass is impressive Nice Mid range, very clear.

Cons: Nothing really except I had to do a little minor alterations in order for them to fit, but truly a great product.

Preacher from California on 8/3/2015

1983 Mercedes-Benz 300CD-T
Crutchfield Customer Review (What's this?)

Several reps at Crutchfield kept steering me towards these speakers, so I took their advice and I'm glad I did. Nice definition in the high end, and as with most speakers they seem to get better as they get played in a bit. There is some bass present - you can hear the notes are there - but of course with only 4" drivers the bass is pretty tepid. Nice to have all the wires and connectors included. Very little physical protrusion of the tweeters, which helped me fit them in dash of '83 Mercedes (Crutchfield recommended 3.5" speakers). Most 4" speakers would have interfered with cars' speaker covers; the Kicker grills would not have worked.

Pros: quality construction, all wires and connectors included, minimal tweeter protrusion

Cons: some speakers in this range include bass blockers, but not these

How To Get The Most Out Of These

T-Dub from Nashville, TN on 4/17/2015

Just picked up these for a few test and would like to say first sorry Crutchfield but found them for less when local store closed. Yes these speakers in a common application will not handle the 75w rms posted by Kicker however I also tested in a few different sized sealed housings and found that with a enclosure 4.5"diameter x 3" deep or shallower they will handle the 75w rms

Pros: Good sound Great power handling

Cons: To get the best out of these requires a lot of extra work that you don't need to do with most other 4" speakers

Great sound

Don't buy kicker from crestwood, il on 11/9/2014

Crutchfield Customer Review (What's this?)

The salesman stated these were 75w RMS. Absolute crap! Metered them at 35watts. When I used my pbr300x4 @ 84watts all they did was distort. Cheap quality Stay away from at all cost! After removing them I chucked them into the biggest landfill in Illinois!

Pros: N/A

Cons: Overrated Fake RMS numbers Not a true 4" speaker

Crutchfield response on 11/17/2014 We're sorry to hear that these speakers didn't work out for you. Sounds like you probably have a handle on things, but remember, our Tech Support team can always help with suggestions for improving the sound quality and how to best set your amp. We're here if you need us. At the very least, please retrieve them from the garbage pile and send them back to us for a refund.

Product Research


Polypropylene Woofer Cones: The Kicker KS-series speakers feature durable polypropylene woofer cones for power and control. Polypropylene is also resistant to moisture and the temperature extremes found in automotive applications.

Balanced Dome Tweeters: The 1/2" balanced dome silk tweeters provide a smooth high frequency response with a wide dispersion pattern. The tweeters have strong neodymium magnets for higher power handling. A semi-dome tweeter has a dome placed inside a cone. Balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter.

4/2 Hole Compatibility: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. The KSC4's mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp. Please check the Find What Fits Your Car application to confirm fit in your vehicle.
