Strong bass adds a whole new dimension to your car's sound system, and Kicker Comp subwoofers give you tremendous bass value for your dollar. You'll hear and feel the power of Kicker bass without feeling like your wallet just got thumped.

Kicker technology at work
Each Comp sub features a flex-resistant polypropylene cone with 360-degree back bracing for hard-hitting lows without distortion. The ribbed foam surround offers long excursion and keeps the cone on target, while double stitching ensures your investment won't come apart at the seams. A tough steel basket provides a reliable foundation for big bass, while extensive venting ensures long-lasting performance that won't break down when the bass gets heavy.

8-ohm impedance for multi-sub setups
Kicker's 10C128 12" subwoofer handles 150 watts RMS to bring out the depth your music's been missing, and its 8-ohm impedance makes it a great candidate for a multi-sub system. This versatile sub works well in sealed or ported enclosures, and it's even suitable for free-air applications.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Subwoofer Features

Polypropylene Cone: The Kicker Comp subwoofer's super-rigid injection-molded polypropylene cone features 360-degree back bracing to completely eliminate flex and distortion.

Ribbed Foam Surround: The optimized ribbed foam surround allows extended cone excursion for additional bass output and higher SPL. The surround is double-stitched to the cone to add a mechanical fastener to the chemical adhesives. This prevents the cone and surround from separating in the harshest conditions.

Spiralead Tinsel Leads: The Kicker Comp subwoofer features durable Spiralead tinsel leads, which are woven into the woofer's progressive-roll polycotton spider, for added strength and reliability.

Steel Basket with Vented Pole Piece: The Kicker Comp subwoofer features a resilient, steel basket with coil-cooling perimeter venting and a vented pole piece for heat dissipation, so the high-temperature voice coil stays cool.

Speaker Terminals: The spring-loaded, nickel-plated terminals provide solid connections for speaker wire up to 10-gauge. Single banana plugs and pin connectors will also fit.

Rubber Magnet Boot: A black rubber boot covers the outside edge of the magnet structure to improve the cosmetics of the woofer and protect the magnet during installation.

Enclosure Compatibility

Enclosure Versatility: The Kicker Comp subwoofer is versatile, performing in vented or sealed enclosures, and in free-air applications as well.

Sealed Enclosure Applications: A sealed enclosure design gives the smoothest response with increased energy at the lowest frequency between 20 to 30 Hz.

  • Compact (minimum enclosure volume): 1.25 cu/ft
  • SQ (maximum enclosure volume): 3.5 cu/ft

Recommended Vented Box Volume: A vented enclosure design is the choice for loud, high-performance bass for SPL contests.

  • Compact: 1.75 cu/ft with a 2.0" x 12.5" slot port opening that is 16.0" in depth
  • SQ: 2.25 cu/ft with a 2.0" x 12.5" slot port opening that is 16.375" in depth

Note: The SQ enclosures generates a flatter response curve and extends sub-bass response.

Infinite Baffle Mounting: The Kicker Comp subwoofer does not require a sealed or vented enclosure for good bass performance. The Comp subwoofer is designed to also be used as a free-air driver. The infinite baffle mounting method effectively utilizes the rear deck and trunk space of most sedan type vehicles.

This is a great little sub. This paired with my JL 300/4 amp is a perfect combination. This sub is detailed, accurate and efficient making every note count. I listen to all types of music and this sub handles them all. I was very impressed with the level of construction quality when I first pulled it out of the box.

Pros: Efficient, tight, well constructed sub at a bargain price.

Cons: None so far (wish I had two of them!)

Kicker Comp 10 & 12, 8 ohm

Written By Jay, Twin Frozen Lakes, WI on Saturday, April 02, 2011

Crutchfield Customer Review (What's this?)

I've used Kicker for some time. They always satisfy me and I know what I'm
getting. The Comp series seems to take all the power that I have to throw at it,
but I don't have too much to throw. It's more sensitive than the CVR series. For
an entry level sub driver, I don't think you can beat them. They are definately
better in several respects than the JL entry level subs I had, which fell apart
and didn't bump like the Comp.
I'm using the 10", 8 ohm version in the house with some bookshelf speakers.
I''m using the slot port box design that Kicker provides in the Technical Manual,
which you can find online if you search. It balances just right and I'm very happy
with the result.
I have 2 12s in the car and it's all I expected it to be.

[Advice: in my opinion, forget that 2 ohm business with any sub. As far as I can
tell, the more resistance, the more the load captures and uses the power the
amp is producing. An amp only produces more power under low resistance
because the low impedence sub isn't capturing it, so it flows right through.]

Crutchfield Customer Review (What's this?)

Do not be skeptical. These things are so dang loud i could easily overpower my music with the bass. Powered by a Fosgate P450.2 225w rms per sub in a sealed box 1 cu. ft. per speaker. I could only imagine how great these would sound in a ported box! Give them 200w a piece and plug your ears.

Impressive subs, for the price - a steal

Written By Timothy, Nashville, TN on Wednesday, July 28, 2010

Crutchfield Customer Review (What's this?)

Picked up a pair of the 8 ohm version to be used with a JL 360.2. Subs running bridged at 4 ohm. They are in an undersized and stuffed enclosure with 1 cubic foot per driver. They work just fine in this configuration. Bass impact is massive and low end extension is not noticeably reduced by the smaller enclosure. They dig quite deep. The JL amp is equally impressive, pushing the subs to near full excursion at about 2/3 gain. Quite a clean little powerhouse - very impressed.

I highly recommend these woofers. While certainly an entry level price the performance is anything but. The only reason to spend more would be to utilize a smaller enclosure. If you have 1 - 1.25 cubic feet to work with per driver save your money and pop for these.

Bang 4 the buck!

Written By weezelhead, Seattle on Monday, June 14, 2010

I picked up a pair of these and threw them in a vented box. I went with the 8 Ohm version because my JL Audio 250/1 amp is 250 watts RMS no matter what the Ohm load is. So I wired them in parallel for a nice easy 4 Ohm load to the amp. These subs BUMP and are also nice and punchy. They play way louder than the THREE 10"subs they replaced.

I have had many different subs in my cars since I got my license 21 years ago, and these Kickers sound better than most that cost me twice as much if not more. I call that Bang 4 the Buck performance. Buy these Kickers!

We've verified that these enclosures are a good match for this subwoofer.
It's critical to have good wire, and none is included with the sub.
Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
Add a grille and keep your sub safe.
These can be useful if you are building a custom box.
