Speaker Specifications

This is the manufacturer product line of speakers.
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.
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.
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.

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.
Carbon Fiber
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.
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.
330 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.
110 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".
86 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).
63 - 24,000 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, required to contain the speaker.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.
4-15/16" x 4-15/16" 
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.

Great sound !

June 25, 2011

I've owned as well as listened to a lot of component sets over the years, I was running the Pioneer D series before I put these in and was about to purchase the Hertz high energy series's when I stumbled on these. For the price Sonic has them and the fact they sound as good as the Hertz can't beat them they are so detailed and clean the mids and highs are perfect ...

great item

July 9, 2012

I own three sets of these great speakers in a Nissan Altima 2006 2.5s, two sets in the rear with a lot of fiberglass, and one set in the front with some fiberglass in the pillars to got that perfect look, powered by a roackforg power series 400.4, excellent product, couldn't ask for better....small problem I kept have was on the midway driver, the grills kept falling off due to bass but was a easy fix with speaker box glue....I promise you, you won't go wrong buying this product.

tyrone, PA

nearly perfect

June 25, 2012

these speakers sound great and get the job done, unfortunatly the installation is a bit difficult for my jeeps sound bar and the box the speakers run through are a little bulky and there is not really room for them to be stylishly located inside the vehicle. also the speaker cover often vibrates out despite the different gummy adhesives we have attempted to use to hold them in place. also upon installation we noticed one of our covers were cracked on the outside, making it not attach securely as well. this could have happened during shipping or it could be their fault for shipping us a damaged product but regardless the flaws are mostly cosmetic. as far as quality goes, these speakers produce the sound we were looking for and in the end, that's what you really want isn't it?

Had these installed on my son's Toyota 4-Runner as a birthday gift along with the SUV itself. My son was so ecstatic about the sounds coming from these speakers. His friends are so impressed, they say it's the best sounding system in the whole school. Thanks for this great product.

Don't know why

March 13, 2012

I got 2 of these not even 6 months ago to put one set in every door, and the back two went out three days after i put them in, i have been doin car audio for years and i have never had as much trouble with a speaker before. I had them under powered below RMS and never even maxed them out. Just the other day the front two went out, but in both occasions the tweeters still work. I can't figure out why this has happend and i don't know if it was Kenwoods or even my falt but i've tripple checked everything. In conclusion i will not buy anything kenwood again because i don't have time to deal with stuff breaking. Not impressed.

Garland, TX

Finally! I got the clarity I wanted

January 11, 2012

I Love these speakers. Installed in my Mazda Protege 5. I have gone from stock 6X8 to Polk DX, to Infinity Reference, to Alpine type-R, to these. If you are considering components, Do it! This is an excellent choice with somewhat subdued highs and plenty of midbass. These are punchy and not too bright. I no longer use my 6" rear door polks for "fill".

These are driven by 75watts per channel crossed over at 85HZ from my Eclipse amp and a Kenwood HU. I also ran new wires direct from the amp when installing these. I am happy with almost no EQ (maybe flat or -1 on mids and +1 on highs. Very musical speakers for classic rock, metal, hair bands, some country and alternative.

Great set of Components

December 6, 2011

I bought these for the front doors of my 02 silverado ext cab truck. They blow away the factory speakers... but that is a given! They have clear and punchy bass/mid bass that you can feel. The highs sound good as well. I do notice a slight lack of upper mid sounds and it can sound on the "tinny" side in those frequencies on some songs. Nothing major and shouldn't keep you from buying these because they are great speakers. This all could be from the fact that 1 the speakers haven't had time to break in good yet, 2 may have something to do with where i mounted the tweeters. The crossovers appear to be well built and have a "shunt" where you can change db's of the tweeters. They are pretty big though so that might lead to a challenge for those with limited space. All in all a great set of components at a great price.

Nice speaker for the money

May 13, 2012

I ordered the speakers to go with my Kenwood double din head unit in my work truck. I was pleased with initial quality and have enjoyed great sound from them these past 6 months. I would not hesitate to recommend these speakers. They are a solid value.
