Speaker Specifications

Series
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.
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.
6" x 8" (also mounts in most 5" x 7" locations)
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 Component System
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 Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
3/4"
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.
Polypropylene
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.
225 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.
75 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).
40 - 21000 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.
2-3/16"
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
5" x 7-3/16" 
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.
No

Love The Kickers!

August 27, 2015

I bought the Kicker 40CSS684 Component Speaker System for my 2002 Miata. I needed the high wattage because I had an 80watt-per-channel Pyle radio - which exceeded the EOM speakers' ratings.

Pros: The crossover box fit nicely behind the in-door mid-range speaker mounts...the speakers perform very well and are a vast improvement from the originals.

Cons: I had to trim the tweeters a bit (with a Dremel tool) to make them fit the tweeter housings...but no degradation resulted.

HIGHLY RECOMMENDED.

Overall pretty good

January 4, 2016

I like the bass that comes from these speakers. They are overall pretty good. My only dislike would be the highs. About 40% of the time the highs are too piercing.

If you can I would recommend the KS series, or the KS series tweeters. These are larger and silk instead of the titanium dome. They also sound much nicer. Just a though.

If installing in a 2010-2013 Mazda3, you'll need spacers in the front. The back will drop right in.

Oh, and these two videos make a big difference in sound quality:

Sonic Electronix Store
These will replace my stock (non-Bose) speakers in my 2002 Miata - for hopefully much better performance. Other buyers indicate these have fabulous sound...I expect I'll be similarly pleased.
Russell T on Jul 24, 2015
I trust the kicker brand and I've been very excited to pick up some component speaker to achieve quality sound.

Do I need to purchase speaker wire?
Ethan L on Jun 19, 2015
Best Answer: Hello Ethan,

That solely depends on your install. However, like John explained, you get a fair amount from the manufacture (no exact length specified).

What is the difference between regular speakers and a component system?
elvis p on Jan 7, 2015
Best Answer: a component speaker separates the tweeter from the mid and has a crossover to dedicate frequencies to each one. it is a cleaner sound and usually requires the use of an amp

I am looking to get two sets of these for my 08 crew cab f250. Do I need an amplifier with this setup?
Also looking for something that will give a fair amount of bass, nothing crazy just some good sound. Is this something I shuold be looking to buy?

Thanks for the help.
Jimmy M on Oct 6, 2015
Best Answer: 1) no, you do not need an amplifier for these speakers. I just ran them off of the existing speaker wires. An amplifier always helps improve over-all performance, but hey, you do what you can!
2) these speakers were definitely a good upgrade for my '99 expedition, so I would definitely recommend them. They have a nice bass/mids for the 6x8's and clean high's on the tweeters.
