Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
CompR / CWR (Kicker)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.
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
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.
500 watts
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.
1000 watts
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.
Santoprene Rubber
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".
95 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).
25 - 500 Hz

Enclosure Specifications

Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Vented / Ported
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
Hatchback Style, Angled Back
The height of the item, measured from top to bottom, in inches.
The width of the item from left to right (side-to-side) measured in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
Second Depth
The second depth is used only when the box is slanted or angled. This value is the top measurement and it is measured in inches.
Wood Thickness
The thickness of the wood the enclosure is made of, measured in inches.
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
Terminal Type
Spring clip terminals work best with bare wire connections with small-gauge speaker wire, or pin-type connectors.

Binding post terminals are a sturdier, more versatile type of speaker terminal. Because binding post terminals are are threaded, you can tighten them down against the wire or connector for a tight, clean connection. The most popular style of binding post terminals is known as a "5-way binding post". This type can accept bare wire, or any of the common speaker wire connectors. Binding posts with the option to be used with banana clips are even more versatile

Spring posts are a hybrid of the two. Instead of using a thread and "screwing" them tight, they use a spring to allow the wire to fit and tighten against the terminal.

Spring posts
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

This box is a great sounding box. I have a 1500 watt amp hooked up to it and it will take it all and remains crystal clear and intense. Great product !!

Awesome Sub!!

January 27, 2014

I actually ran across this set up at a pawn shop. I looked up the specs on it and thought it should really pound. I bought it at more than a 100 less than you can buy on the internet. I took the sub out of the box and saw that it was set for 8 ohms. Moved it to 2 ohms and boy was I blown away by the bass this puppy puts out! I've got it being pushed by a Alpine MRP-M500 and it just pounds this sub. I'm very impressed! It really shakes all the mirrors and moves my wifes hair while listening to loud bass songs. This is in a Dodge Dakota quad cab with the small seat removed. If you pair this up with at least a 500W amp you won't be dissapointed.

Unclear specifications

February 24, 2015

So far, so good.....

However, this sub model was misrepresented at the time I purchased it. It clearly stated on this site, as well as other popular audio equipment sites, that it was rated for 800 watts RMS power, and 1600 watts at peak power.

This is clearly not the case, as it now states (on this site as well as the Kicker packaging that came with the sub) it can only handle 500 and 1000 watts. This concerns me now because I paired this sub with a Pioneer GM-D9601. The Pioneer amp is rated (at 2 Ohms) for 800 watts RMS power, and 1600 watts peak power, so naturally I'm concerned about whether or not the sub can handle this power.

As I said, all is well now, but I advise people to quadruple check their research of this model before committing to purchasing this sub.

As far as performance, it hasn't disappointed, but I'm VERY wary when it comes to turning up the volume/bass when I have music playing. Maybe others can input their experience from the same time that I purchased it.

i am a fan of music but not knowledgeable on the details of products. i can say that i am very happy with my purchase. i receive the sounds that i am looking for among rap, hip hop and r-n-b music. i have the recommended amplifier for this kicker as well and have not had any problems with either products.

Great sound.

October 7, 2015

I bought this before it went on sale for 50 bucks more but it's still well worth the money. I have it running off a kicker dx 500.1, gain set perfectly with a dd1 (gain is NOT a volume knob for those who have blown this sub). It's getting a clean 587w rms per the amp birth sheet and sounds loud and crystal clear on any music and has for 3 months now. I have zero complaints. It's paired up with a kicker dx 500.1, 2 dx 125.2 amps on a kinetic hc1200, 2 each of kicker 6x9, 6.5 and 4" speakers. Livin loud

Is this brand new?

Best Answer: No kicker is not a new brand. I personally have been using kickers for around 5 years!

I want to get this sub but I'm using a 5ch amp with 440w coming from the sub channel at 2ohms. Would a 5ch amps sub channel give this sub the power it needs? Meaning would it give it the power to bump like it should being a 5ch, or would a mono block work better?
A shopper on Apr 22, 2015
Best Answer: Hello,

A monoblock does not have any magical benefits vs a 5ch . =]
As long as the power output of the 5th channel is on par to what the driver is calling for then it will work just as well as a monoblock. In fact, the 5th channel of a 5-Channel is a small monoblock. The 440w is clearly the amplifier's only limitation. A monoblock doing the same power isn't going to give you any gain. "Bump like it should" is relative, but if you are attempting to reach the full potential of the driver then that will require power closer to the 800w RMS referenced in the specifications.

what is the tuning frequency?
RIcky on Apr 21, 2015
Best Answer: Hello Richard,

Kicker doesn't provide this information. However, when we asked them this at their recent training, the trainer said they often shoot for ~40hz .
