Kicker KS Series

Does a serious factory upgrade, with more muscle at an affordable price, sound too good to be true? What it sounds like are some of the loudest, clearest coaxials ever hidden behind a door on under a back deck.

Give factory sound a serious power injection with a KS-Series Coaxial Speaker upgrade. With added improvements on the woofers and tweaked tweeters, dropping them in where factory speakers were seems like a no-brainer. The curvilinear, gray woofer cones, Santoprene surround, and newly designed basket give KS Coaxials the extra brawn to deliver a smooth, rich sound at any volume.

The tweeters contain a stout neodymium magnet dipped in ferrofluid for maximum coolness, recreating highs that rival live performance. Give your system the upgrade that it deserves with Kicker KS!

Speaker Specifications

This is the manufacturer product line of speakers.
KS (Kicker)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Balanced Dome
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Santoprene Rubber
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
40 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
20 watts
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
88 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
80 - 20,000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
Bottom-Mount Depth
The depth when installed from the bottom of the mounting surface. Measured from the bottom of the speaker's magnet to the top of the mounting holes on the rim of the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
3-3/16" x 3-3/16" 
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

Replacement Dash Speakers

March 30, 2012

Affordable, Simple, Crisp and clear speakers.
I used these to upgrade my stock stereo, I first had them connected to a stock head unit and they made a huge difference in sound but then I added my new Deck 4x50watts and these things really woke up!
This is a must do to any stock car stereo to really hear what you have been missing.

April 5, 2012

I have 96 honda accord coupe. I ordered two sets of these (total of 4) to replace both front 6.5's and both rear 6x9's. Crazy right? They're only 3.5's; that won't sound right.....wrong! These are incredible, clean, crisp, and they absolutely scream; also put out a little bass if you need them to.

Listen, paying high dollar for stock replacement speakers, and then getting mediocre sound running off a 50x4 (so 20rms to each speaker) head unit won't cut it, so you buy an amp right well that's when it gets pricey and wirey. Look at the specs, these speakers put out 20 rms max each, so, running off my cheap jvc 50x4 head unit, these speakers are getting full power.

Quality- built like rocks, they're heavier than my stock speakers and the magnets are bigger. Extremely versatile, they're only mounted with one screw in the doors. Look I'm running these with just a head unit and a sub, and it's like I'm in a theater. Amazing. If you read my review, trust me, it worked for me; don't listen to "experts." I had plenty tell me only using 3.5's will be weak.

I found a loophole: big expensive speakers and amps are a thing of the past. I recommend running what I have (4 of these, 10" sub and a mono amp) to power it along with any 50x4 head unit.

highlands ranch, CO

sound good

February 7, 2012

I have these combined with the Kicker KS693 and it's a good combo. They sound good for a small speaker. I'd recommend going to the 4" though if you can squeeze them in.

Covington, WA

Installed in Miata Headrest

May 26, 2011

Put these in the Miata headrest and wired them in 8 ohm so I can power them by just the rear channel of the amp, that way I can use the fader to control the level of headrest separately from the Polk components up front. Higher levels to these Kickers sound GREAT with the top down! These speakers do exactly what I wanted, and Sonic has them at the lowest price!

Cleveland, OH

They sound excellent but be careful

March 25, 2011

Great speakers for the price. I have a Dual XDMA6415 head unit 17w x 4chan. No amp is really required for these ones. I was not exactly sure if I received a defective speaker, but within 3 days of installing it blew out. Thankfully the people at Sonic Electronix are going to replace the speakers. If you are on a budget this is certainly a good start and they sound infinitely better than the factory speakers in my 1995 318i convertible.

Madison, NH

Better then I thought

March 18, 2011

I didn't think these 3-1/2" would sound as clear and hit as hard as they do. From looking at others, I thought the bass wouldn't be good. The have clear noise and good bass. I would recommend these to anyone who needs 3-1/2"s. I used these to replace my stock Delco ones in my 94' Cutlass Ciera.

Sound good, but a little tricky to install.

August 1, 2012

I would recommend the speakers, but if you're putting them in the dash of a jeep gc, you need to do a little online research to make sure you know what is involved. It takes a little soldering work to get it to fit. But they do fit well eventually.

hayward ca

not good at all

March 27, 2014

I bought these and installed them in the front dash in my 88 cavalier Z24. The stereo is a stock delco cd player from a 92 buick park ave. They started crackling a week and a half after installation. It looks like it couldn't handle the bass? The stock speakers were fine after 26 years and these blew that quick? Its not even that loud. Very disappointed. Aren't new speakers supposed to be better then this?

Why did you choose this?
Sonic Electronix Store
Kicker is a top quality company. This particular speaker had great reviews. I liked the frequency range of 80-20000 hz along with 40 watts RMS.
Rory O on May 13, 2015
Will they fit into the kick panels on each side ?
A shopper on Aug 27, 2014
Best Answer: Hello,

You did not specify a vehicle, so we cannot confirm fitment. Use the following link to establish sizes.

Typically 3.5" are meant for strange locations, and often need a bit of help to mount properly, so be prepared for that.
