You put some good bass in your car, but now your speakers just aren't hanging with your subs. Kicker designed their KS Series component speaker systems to deliver the performance you need to bring that "live music" experience to your ride.

The KS5.2 component system features heavy-duty 5-1/4" polypropylene woofers supported by Santoprene rubber surrounds. These speakers can handle high-level playback without straining, especially when they're powered by an outboard amplifier.

Titanium 1" dome tweeters broadcast plenty of high-frequency sparkle, so you'll hear all the sonic details that make your tunes exciting. External crossovers direct the right frequencies to the tweeters and woofers for optimized performance, so you'll hear detailed, natural sound. Power these components with a nice amp, and you'll hear how these quality component speakers make your music more immediate and real.

Great set of speakers

Crutchfield Customer Review (What's this?)

Excellent speakers. I'm very impressed with how much I can turn these up without distortion as well. IMHO, the reproduce sounds very clearly and accurately. My only complaint is the slight 'tin-iness' they have, but I suspect this is from the Titanium woofers.

Pros: -loud/able to handle a lot of power from receiver -clear vocals and instruments -easy plug and play installation

Cons: -a little tin-iness -very limited bass range

Why did I wait so long...

2005 Toyota Corolla
Crutchfield Customer Review (What's this?)

2005 Toyota Corolla CE with stock system for 9 years = boring...Upgraded to Pioneer head unit, Alpine amp, JBL bass, and these Kicker Speakers = not boring. These speakers definitely make a huge difference. The old Toyota cardboard cone speakers (14.5W) uff da. I am hearing tones never heard before in this little car. These tweeters and midranges would definitely overpower existing lows so definitely add the subwoofer if you add these speakers. Took about 1 hour for front speakers, 2 hours for rear speakers due to all the plastic trim, seats, etc. that need to be removed in the Corolla. Crutchfield step-by-step instructions and a quick question to their advisor's (answered immediately) made this a snap. Now onto the 1997 F150 upgrade...

Pros: Simple, easy installation, crossover's easy to mount inside door panel, sound fantastic!

Cons: None yet

Good Price + Installation Options

1998 Jeep Cherokee
Crutchfield Customer Review (What's this?)

I bought these on sale along with the 6.5" version for a 1998 Jeep XJ Cherokee. Powered by an Alpine KPT-445 they play clean and clear at any volume level. The tweeters are not harsh and the woofers provide good midrange. Install was super simple in the stock rear headliner location by installing the tweeter in the center of the woofer like a co-axial speaker. Most component speakers require custom mounting holes for the tweeters, but these have the additional option of mounting the tweeter in the center while utilizing the factory speaker grills. Had the option of putting the 6.5" units in the rear as well, but would have had to make modifications to the factory speaker locations. The 5.25" speakers don't provide as much mid-bass as the 6.5", but don't require any mods to install for my application. Would definitely recommend these to others.

Crutchfield Customer Review (What's this?)

I bought 2 pair of the kicker 5.2 component speakers for my 2008 F 250 crew cab along with the JL Audio 5/500 amp and a Kenwood 8" shallow mount Sub for my factory sub cabinet along with a Pioneer 4300 dvd head unit. This system absolutly rocks once you get the amp fine tuned... Thanks Crutchfield for all your help in putting my system together... You have a customer 4 life...;)))

Clean mids and highs that scream in the doors of my F150. Crossovers were even easy enough to bury in the panels.

Product Research


Woofer Cones: The Kicker KS-series speakers feature durable Polypropylene woofer cones, resistant to the moisture and temperature extremes found in automotive applications.

Santoprene Surrounds: The woofer surrounds are made of Santoprene rubber to allow extended cone excursion for additional bass output and higher SPL. Santoprene is durable and resists moisture for a long life.

6x8 Adapter Bracket: For mounting flexibility, the woofer can be mounted in 6x8 applications using the supplied bracket.

Grilles: The KS5.2s come with graphite-colored, plastic, spoke-style speaker grilles.

Tweeter Mounting Options: The tweeters come with brackets to allow multiple mounting configurations; flush-mounted, angle-mounted, and surface-mounted:

  Flush Angle Surface
Mounting Height 0.322" 0.716" 1.195"
Mounting Depth 0.775" 0.631" screw depth
Frame Diameter 2.323" 2.323" 1.911"
Cutout Diameter 1.753" 1.753" N/A

Coaxial Tweeter Mount: In addition to standard tweeter mounting options, an innovative tweeter mounting post lets you mount the tweeter directly to the center of the woofer, giving you a standard coaxial speaker. When the tweeter is attached to the woofer the mounting height increases to 0.935" (top mount) and the tweeter protrusion increases to 0.677" (bottom mount).

Crossovers: The component system includes passive 2-way crossover networks for a seamless transition between the woofers and tweeters. The slope is 12dB per octave (both high pass and low pass) and the crossover point is 4000 Hz. A switch on each crossover allows you to attenuate the tweeter output; 0 dB, -4.5 dB, or -9 dB. The crossovers' dimensions are:

  • Length: 5.718"
  • Width: 3.012"
  • Height: 1.487"

I run mine just off of my kenwood and it works fine [ STEVEN  Jun 09, 2014 ]
Yes you need a small amp my truck has one from factory built in for the on- star that's what I used good luck with them [ JUAN  Jun 04, 2014 ]
You don't need an amp at all. I run these off my stock head unit and they sound great! So you should be fine with out an amp, but having one would only make them sound even better. [ JOHNATHAN K  Jun 03, 2014 ]
I have the ix1000.1 powering a pair of these and a pair of 6.5's and they sound excellent! I always recommend amplifying midrange coaxials and components with at least 50 watts rms. [ ROY  Jun 03, 2014 ]
Hi Daniel, I have recently installed these speakers in a 2005 Toyota Corolla and they really livened up the car. They replaced the 12W paper cone stock speakers. I installed a Pioneer DEH-X8600BS head unit and did provide extra power with an Alpine KTP-445U Power Pack which provides 45W RMS x 4. I purposely stayed below the 65W RMS for the speakers to ensure they would last for awhile. Honestly, I would bump the power up to at least 45W RMS. They get plenty noisy in the Corolla and I suspect your Volvo is a little bigger. I know I wouldn't want to go down to 22W in the Toyota after hearing the Kickers with the Alpine providing the extra punch. Hope this helps. [ Kent  Jun 03, 2014 ]
Hey I have a pioneer avh-x2400bt head unit that puts out 54w per channel and have this setup with out a amp and it sounds great u might need a amp im hooking mine up to a amp soon they can take 300watts.over all very good component set [ SARA  Jun 03, 2014 ]
The radio it self is enough but the sound quality is going to be lacking since the component setup. For optimal performance an amp is always suggested but not required [ STEVEN  Jun 03, 2014 ]
My kenwood puts out 50 watts per channel and that gives me 100 db output so it's really a personal preference of how loud you want it to be. But I would if I were you [ clifford  Jun 02, 2014 ]
I was told not to run them unless you had at least 50 watts per speaker. I had them under powered and they blew. So I would recommend getting an amp to power them. [ DALE  Jun 02, 2014 ]
