Priced Per Pair

Speaker Specifications

This is the manufacturer product line of speakers.
CS (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.
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
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.

PEI (Polyetherimide)
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.
Polyester Foam
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.
90 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.
30 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 - 20000 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" x 3" 
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.

These small puppies are still going strong and have become a piece of technology I just cannot do without. It is very clear and I can hear fret buzz of the guitars in acoustic music, it is so clear. Highly recommended. :D

Good speaker for a dash replacement

September 18, 2013

Overall not a bad sounding little speaker. the tweeter can be a bit harsh, but I tend to prefer the smoother highs of a silk dome tweeter. Other than that the vocals are good, power handling is ok and they helped raise the soundstage up to the dash

cant believe how great these little things are.have 1 mounted in each front door along with a set of 6.75 components.was wanting to fill in some midrange i felt was missing.ive got 80 watts going to each and these things are awesome.the 3 1/2 brings so much more mid to my system,and the extra tweeter really just brings things out.i dont have them run at full range,ive got them cut off around 175 htz.they do exactly what i was hopeing for and so much more.awesome deal through sonic also.

Nice little speakers

October 18, 2014

These were suppose to be temporary replacement dash speakers for my Chrysler; the stock speakers were so bad in my car I never listend to music, but now I do! These actually surprised me, sounded better than I expected. The synthetic film tweeter is not "harsh" and works very well on low powered systems. I have mine high-passed at 400Hz, otherwise if you run them too low they will suffer; I bet they would do just fine with an amplifier at 600Hz if you can control the level.

Good upgrade

April 13, 2015

Replaced the pillar speakers in my suburban. Had to drill into the frame and cut some plastic on the panel because the stock speakers were an odd size and shape. Head unit is driving these and I added 600 Hz bass blockers. In hindsight, 300s may have been better. Took a while to balance the sound with the other speakers connected to the amp, but I'm glad I put these in. They are a great upgrade to the stock speakers.

Better than Rockford Fosgate.

January 29, 2014

These little buggers have a better sound quality than my RF Prime 6x9s. Sorta makes me wonder, what the 6x9 of this brand and line sound like. For example it's more bass responsive and clear.

Old truck--front dash speakers/tweeters
Kenneth S on Jan 30, 2015
Will these speakers work well with my late 1960's Blaupunkt "Frankfurt" AM/FM/ SW/LW car radio? I am not sure if the radio has enough output to power these. Would you suggest a different speaker? Thanks
William N on Feb 8, 2015
Best Answer: Hello William,

You are correct in assuming your headunit will not provide enough power to push the speakers to their potential . However, that is Not a 'bad' thing. In fact, speakers like the 40CS354 are designed to be able to perform with even a Fraction the intended rating. This means, your headunit will surely provide enough power to get a desirable outcome.
