The best balance between high value and high performance!

The famous Kicker Comp subwoofer provides excellent Kicker bass, while sticking to a tight budget. The Comp subwoofer has been redesigned for 2010 with looks that are stunning and technology that is time tested. Some of the engineering behind this subwoofer is the extremely rigid injection molded cone. The cone has been adjusted to match the 2010 Kicker line of subwoofer, but it still keeps it traditional black and yellow design that the Comp is known for. Behind the cone, the subwoofer features 360 degree back bracing, a vented pole piece, Kickers Spiralead tinsel leads, and a sturdy steel basket. This legendary Comp subwoofer from Kicker is the perfect balance between high value and high performance!

A 12" Kicker Comp subwoofer is the most common size of subwoofer purchased and installed into a vehicle. These 12" subwoofer provide top-notch response when playing at low frequencies. The size of the cone and structure make it perfect for most applications and the perfect size for accurate bass. This subwoofer is also available in 8", 10", 12" and 15".

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Comp (Kicker)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
300 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.
150 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Single
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
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
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).
27 - 500 Hz
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".
88.3 dB
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
Yellow
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.
SoloKön
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.
Ribbed Poly-Foam
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
Optional (Accessory required and sold separately)
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.25 cubic feet
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
3.5 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.75 cubic feet
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.25 cubic feet
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.
5-7/8"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
11"
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.

No

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 – 10.
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 – 10.
Efficiency Bandwidth Product (EBP)
This number represents the trade off between having an efficient woofer and one with a wide bandwidth. To calculate this number, take the Fs and divide it by the Qes. If the number is below 50, the woofer is designed for a sealed enclosure only. If it's between 50-100 it can be used in either. Lastly, if it's greater than 100 it's designed for vented enclosures.

works great

October 19, 2011

I have had these for three months and they still are working fine. I was use to ten inch when i got these. I thought they were loud. then i got use to them and then they broke in and they were really loud. I still have them and they turn plenty of heads when i drive. i have them hooked up to an 800 lanzar amp and it is perfect it pushes them more than enough. They shake everything in my car. they knocked off my parking pass off of my mirror one day on my way there. I was shocked, i never had that with my old system.

Nice Subs.

August 22, 2010

I have these subs wired up to a 1000 watt Sony Xplod amp. Lower end amp and the sound quality is incredible. Definitely worth getting. I push them hard, and there is nothing but crystal clear sound.

great buy

July 17, 2010

I just bought 2 of these I have them wired at 8 ohms on my kicker zx750.1 and they hit pretty hard. I have each one in a 1.85 cubic foot custom ported box and it makes your hair and seat shake and with the highs you cant see straight and they aren't even broken in yet. I would recommend these to anyone who wants a banging system with not a lot of cash to spend.

Nice budget subs!

October 21, 2010

I've have 2 of these installed in a sealed box. The subs do well for any type of music I've tossed at them. Currently they have been in for 10 days running @ 4 ohms, that's gonna change today when I wire them down to 2 ohms. Will be getting a ported box in the future to drop these in but they are running nice and clean. I had 2x Hifonics subs, just the basic entry level. They did well but compared to these not so much. I'm very happy I decided to try the Kicker's out. Only thing I can think of that would grant these as a 4 star sub is the low's on some rap songs don't get thru, could just be from the sealed box but will find out later. They are powered by a standard 1k watt @ 2ohm amp, my gain is up to around 90% But I would say for someone that cant afford to drop thousands of bucks in their systems to give these a shot. Very nice stiff cones but that does kinda scare me as I don't have any speaker grills so yeah, nothing in the trunk till then xD.

November 3, 2010

My friend bought 4 single 4ohm and we threw them in a vented box wired to 2 ohms on a lanzar 600x4 amp ( bridged to run all channels) and these subs slam real good. The sound quality isnt that good but if your a basshead then youll be happy with them, but my 2 type r alpines where louder.

Great entry level subs

July 5, 2010

As far as entry level subs go, i don't think it gets much better than this. These subs are probably the best sounding subs in this price range, sounding better than some other budget systems i've heard. Some cost cutting is evident, with the rubber surround not feeling quite as sturdy as the ones on my friends CVRs, but overall they are still pretty sturdy. Right now, i've got these subs in a sealed box, wired in parallel so i think they are at around 2 OHMs. They definitely arent the loudest subs ive heard, but then again that has a lot to do with the crappy amp i'm running right now. For what you pay, i think these are some of the best subs out there
