About 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.

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.

How do you properly measure speaker size to ensure best fit?
[ DeHartShadow  Nov 27, 2015 ]

We've done the measuring for you. Just enter your vehicle information into the "Outfit My Car" application and the website will filter the models to show you the ones we recommend to fit a specific factory location in your ride: I hope that helps!
[ Ryan  Dec 02, 2015 ]  Staff
these speakers are rated at 75W RMS. is this rating for a single speaker or for the package of 2?
[ Vamsy  Jan 14, 2015 ]

Hi Vamsy: Each speaker is rated for 75watts. I installed an Alpine 4 X 75 amp and it works perfectly.
[ DAVID  Jan 15, 2015 ]
they are rated for each speaker. but if you push them at 75 they, like any speaker, will distort unless you have a cone/enclosure/ or baffling of some type.
