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.
4" x 6"
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.
150 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.
50 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).
50 - 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.
4" x 6" 
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.

Great buy

March 16, 2014

These are a great buy.i put these in my 2014 peterbilt 386 daycab and they sound amazing with the stock deck bass hits decent but what else would you expect from such a small speaker but overall a great choice with the rms rating being as high as it is

these speakers are awesome for their size, highs are crystal clear not real good for midbass just good for rounding out your sound stage as they are not 6x9s or 6.5s.

Not bad for Kicker...

November 1, 2013

I am not a huge fan of Kicker but I was actually impressed with these speakers. I installed them on a 2002 cavalier and fit perfectly and they have good mids, and highs. Very pleased over stock speakers. Would recommend to anyone interested from upgrading there stock system.

The Jungle, WA

((((((Most Excellent))))))

December 24, 2013

So here's the gist of why I'd give these an overall excellent rating:

Better key specs than most other 4x6's I see available; these can handle 50W RMS and they can play bass tones down to the 50Hz level. Although other 4x6's come in with a higher sensitivity level, 88db powers perfectly fine straight from the head unit.

Other 4x6's typically come in with a lower RMS rating and will cut-off at the 70-75Hz level, thus challenging you to make them balance well with whatever other speakers you may be running, amped or not. (I can't imagine amping a speaker with a 25-30W RMS rating and a bass cut off of 70-75Hz, it would distort too easily if you going for high power)

These Kickers mounted straight on to the dash pad of my 80's GM car, and are balanced out with a set of 6x9's in the rear. Currently, I'm just running all four speakers straight from the head unit, no amps or subs and I'm really surprised at how well balanced this base set up is. Of course, I'll be adding amps + subs, but the first goal is to achieve an excellent base/platform from which to amplify.

*In most cases I've had an aversion to speakers with PEI tweeter compositions on the notion that they would sound harsh. But that's CERTAINLY not the case here. I find the highs to be smooth and controllable, not too bright or distorted when cranking. Of course, the natural variances from one car interior to another will play a factor in a speakers' audibility. But I think other listeners will feel likewise.

I have these mounted in the back doors on my 2003 Silverado extended cab with a Pioneer CD/DVD/GPS system. Used as subwoofers. Not too much bass. (You can adjust Sub frequency below 50hz but its set at 63hz now. Why are these being used as subs/which would be a good speaker for this application? There's Kicker mids and separate tweeters in the front.
John M on Apr 11, 2015
Best Answer: Hello John,

The lower the frequency you wish to reach the More you will require to properly get the performance you expect. With that said, your limitation is that of the headunit, which is likely roughly 20watts, at best. In addition, the speakers are Physically incapable of playing any frequencies below 50Hz, so even if you get the proper power to them, you still may not get the result you want and/or you may harm the speakers. Needless to say, they aren't intended to be used solely as subwoofers, but can be, but only will if you understand and accept the limitations of the idea. Point is, you will want to add an amplifier, even if its a small one.
