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 Titanium-domed 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

Series
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.
Pair
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.
5-1/4"
Design
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.
2-way
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.
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.

Titanium
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.
Injection Molded Polypropylene (IMPP)
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.
135 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.
45 watts
Sensitivity
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".
90 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).
45 - 21,000 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.

Yes
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.
2"
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.
2-1/4"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
4-9/16" x 4-9/16" 
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.
Yes

These Made the Biggest Difference of all i bought

December 4, 2012

I recently bought Sony Deck 50w x4 Sony Xplode 6x9 floor front (above 2, an unbeatable Black Friday deal at Best buy) Kicker KS525 Kicker KS693 6x9 read sides (above 2, here at Sonix) put into a mid 2000's Grand Caravan. Of all the speakers i bought , these 5.25 kickers make the biggest jump in sound for me, They are immediate, full sounding dashboard fronts that make my late 80's early 90's Hi-NRG dance music come forth in full glory. The Mids and Highs are well rounded and can be EQ'd to be overkill, lots of room to grow when playing with the -6 to +6 on the dials. The Lows of this are present but like most say, don't expect them to thump you, expect them to "fill out" the bottom range for you (and thump just a tiny bit :) Turning my cd's up to about 40% makes my system in this minivan sound like a club. I cant turn it up too much more, (in my 40's, mostly looking for well balanced sound, the days of wanting to rattle the trunk off are long gone) At about 40% the volume brings out the threshold of these speakers where they open up and WOW me. I bought these speakers here at SonicElectonix. I called first with questions and the guy on the phone was happy to get my call and super helpful and knew his stuff, I would gladly buy from these guys again, the shipping from KY to FL took 3 days total. I am looking forward to Christmas deals here at Sonix, I have a Subwoofer and Amp yet to buy! BTW, I had Best Buy put these speakers in for me and they did a nice job. They installed 2-6x9's and 2-5.25 for around 150bucks. Tearing apart the dash and yanking panels off the rear walls doesn't sound like fun to me so maybe some will think it was a tad pricey, for me it was a nice ending to a great shopping experience here at Sonix. Overall, These KS525's are WELL worth the money. Get them, You will NOT be disappointed !

Great speakers, these are real good especially for the price, u cant go wrong. I bought all new speakers from kicker to replace the factory ones and with no amp powering these, just a head unit they soumded dam good, now obviously they are no subwoofer so do not expect deep ass bass u would get from a 12 inch but they do complimebt any speaker system nicely.

awesome sound for the price!

August 23, 2011

Put these in the rear of my dodge ram after I blew the MTX's. I did have them amped pretty good but now they're just powered by the kenwood head unit. Sound really goood either way. Dont throw too much bass to them amped or they will distort. Thats not a problem since I put my subs in. Overall excellent speaker for the price!

Little expensive but they last forever

June 26, 2011

Sound great. Perfect fit in a 2002 Buick Century, front door panels. The tweeter doesn't protrude too much from the top of the cone so it should work well in most installs. 45W rms is more than any head unit is capable of producing so there's room for expansion. Been in love with kicker products for 10 years now.
