Our take on the Kicker KS5.2

by Jo Greene

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

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.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.


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"

Great for high frequencies

Written By Cayle, Show Low AZ on Tuesday, July 08, 2014
Crutchfield Customer Review (What's this?)
I got these for my 91 Dodge Shadow. Great product. I recommend high note use only, don't handle low notes too well.
Great sound clear and crisp.
Don't use for low frequencies.

Great set of speakers

Written By enjid, Arizona on Thursday, April 24, 2014
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.
-loud/able to handle a lot of power from receiver -clear vocals and instruments -easy plug and play installation
-a little tin-iness -very limited bass range

Why did I wait so long...

Written By Lindo, Minnesota on Tuesday, February 25, 2014
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...
Simple, easy installation, crossover's easy to mount inside door panel, sound fantastic!

Good Price + Installation Options

Written By Anonymous, Colorado Springs, CO on Wednesday, September 07, 2011
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.

How much power is recommended to run these? I have an aftermarket kenwood that puts out 22 watts per channel. Do i need an amp? 2001 volvo s40 [ Daniel  Jun 02, 2014 ]
9 answers
  • 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 ]
So, if I mount the speakers on my Wrangler sound bar, where do the crossovers and tweeters go? [ LB  May 24, 2014 ]
