Kicker's Comp subwoofers combine high performance with powerful lows to enhance your vehicle's sound system without draining your wallet. The 07C124 12" subwoofer uses a rigid polymineral cone and double-stitched, ribbed foam surround to deliver strong bass from sealed or vented enclosures, and you can even use it in free air applications.

Kicker fortifies their Comp subwoofer with a rock-solid steel basket, and keeps it cool with perimeter venting. The famous Inverted Structural Dome design reduces cone flex that can lead to distorted output, so the Comp can handle plenty of power without blowing a gasket. Kicker rounds out this handsome sub with nickel-plated push terminals for quick hookup.

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.

Product Research

Enclosure Compatibility


Cone Materials: The Kicker Competition woofer consists of a vacuum formed polymineral cone with an inverted structural dome (ISD), which remains rigid to minimize cone flex and lowers harmonic distortion. A rear cone brace integrates into the cone with a continuous contact perimeter weld, which offers unmatched strength and resistance to deformation under pressure.

Surround: The optimized Polyfoam-ribbed 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.

Enhanced BAM (Basket And Motor) Assembly: The high-strength steel basket features a low-profile open design, and provides a solid foundation for the precision-aligned motor assembly. Perimeter venting in the BAM relieves pressure from under the spider, supports a linear excursion, and helps dissipate heat from the voice coil and motor structure.

Voice Coils: The ultra-strength voice coil sustains enormous cone excursion and provides extra heat dissipation. The high-temperature Polyimide Film voice coil former improves sonic and conductive properties, and prevents thermal-electrical meltdown.

Construction: The woofer features a two-piece vented hyper-extended blackened pole piece and backplate. This unique design provides the following benefits:

  • Optimizes heat transfer efficiency for cooler operation and maximum power handling ability.
  • Eliminates erratic magnetic flux from the voice coil gap.
  • Releases pressure under the suspension for uniform cone movement and responsive low bass.
  • Prevents the voice coil from bottoming out and corresponding damage.

Tinsel Leads: The woofer features high-power tinsel lead wires to resist breakage and power-robbing resistance losses due to the common use of "insufficient gauge" lead wires.

Speaker Terminals: The spring loaded, nickel-plated terminals provide solid connections for bare wire up to 10 gauge.

Enclosure Compatibility

Free Air Applications: Kicker Competition subwoofers can be very effective in an infinite-baffle (free-air) installation. You may need to reinforce the rear deck of your vehicle to support the weight of the subwoofer (3/4" MDF is recommended).

Recommended Sealed Box Volume:

  • Compact (minimum enclosure volume): 1.25 cu/ft; the woofer can handle up to 250 watts RMS
  • SQ (maximum enclosure volume): 3.5 cu/ft; the woofer can handle up to 150 watts RMS

Recommended Vented Box Volume:

  • Compact: 1.75 cu/ft; 1.5" x 10.5" port opening; 14.5" port depth; the woofer can handle up to 150 watts RMS
  • SPL/Deep Bass: 2.25 cu/ft; 1.5" x 10.5" port opening; 13.25" port depth; the woofer can handle up to 150 watts RMS

Note: The power handling specifications listed with the vented enclosure recommendations apply only when a 25Hz, 24dB/octave subsonic filter (sold separately) is used with this woofer. If a subsonic filter is not used, power handling may decrease, excessive port noise can occur, and the life of the woofer may be shortened.

kicker 12 & MTX rt 202

Written By cody, lyman, WY on Tuesday, October 27, 2009

i got this sub about a year ago......i have it in an MTX large ported box with an MTX rt 202 amp, and it produces 703 watts max, 224 rms. the original MTX 4500 12 blew, then a jvc 12 blew, both after about three months, and everything was tuned correctly and very stable. i got this sub, based on the reviews that it can handle more than rated and the good news everyone had about it. as with my others, i broke it in correctly, and wow. In my 86 dodge ramcharger, its just amazing. neither of the other subs sounded near as loud or deep and didnt last as long as this one has. it plays very quick clean sound, and very boomy bass. not as good for highs, but still very well. i actually watched a crack in my windshield grow longer with each time my bass would hit. the only system that i have heard that was almost as loud as mine was a infinity perfect in a large custom ported box, running an infinity amp with about 1200 watts max. i have heard many other duel sub systems and systems with twice the power of mine that dont come close. there was a guy that had two JL 12s in a sealed box running what he said was 1800 watts with a capaciter, and it wasnt even close. maybe he had a bad setup, but it wasnt near as loud as my setup. these subs handle twice what they are rated, and i am very impressed. kicker all the way

I put two of these in my ford explorer and i could not have asked for more. These kickers are a quality set of speakers and they are a really good price. They bump a lot harder than i thought they were going to and i am so glad i went with these kickers.

amzing subwoofer

Written By wikedsik, central point or on Monday, July 13, 2009

ive got two of these bad boys hooked up in my 1995 ford f150 and its a major improvement from my old sub p1 punch. surprised at how hard these hit recommend them to anyone.


Written By compken, Fort Wayne, Indiana on Thursday, June 11, 2009

I just bought two of these in a sealed box and I must say, AMAZING. I have a kac7201 bridged to them and they slam so hard my windshield wipers jump alittle bit. I was truely amazed on how hard they hit. The down fall is that they don't have extremely great extended bass, but if you want hard hitting bass they are GREAT. Love these subs.

I have had these things for about a half a year and they still hit hard. great
speakers for an awesome price. they are also way under rated i have two

Written By Swatts, Alphachetta, Ga. on Thursday, February 05, 2009

I just pulled these out the box and hooked them up to my 300 watt amp,

yo momma..and I ain't even violent.

under rated

Written By ricky, chicago,il on Wednesday, August 13, 2008

i would like to start off by saying thanks crutchfield for all the help. i just
bought this sub for a friend of mine and man this thing hit hard.i had a pair
in a sealed box and it hit hard.but the one i got for my buddy came in a
ported box and sounded twice as loud.i would suggest this sub to any one.

Excellent Subs!

Written By Michael, NJ on Tuesday, August 05, 2008

These are great subs. They are very loud for their power rating. I bought two of them from Crutchfield during a special. I already have subs in my car, so these are a cheap solution to fill my room with loud bass. They definitely handle more then they say. I have them hooked up to an old Kenwood receiver with a low crossover and they slam. There totally worth the money.

Crutchfield Customer Review (What's this?)

These are amazing. They are priced way below what they should be selling
them for. They hit so hard i have things rattling in my car i didn't even think
could rattle. One thing though in the features and specs these say they can
run free air. DON'T DO IT!! I tried it while i was waiting for my box to be
built and yea they sounded alright but once i dropped them in that box and
turned them up it was like a whole different set of subs. Much less
distortion and 10 times the bass with the box. Overall, a sweet deal.

Crutchfield Customer Review (What's this?)

I have a set of these kicker comps; and let me say that they pound!!!. With a great box and a 'great' amp it will most definately be one of the best sounding subs with great to excellent bass. BELIEVE ME!!!

p.s. These babies can take more pounding that it states.
p.s.s. I have a pair wired to a 750 watt amp.

Great Bump for the buck

Written By Derek, Sand Springs, Oklahoma on Monday, June 30, 2008

You look at all the other reviews and they use words like "wow great and
loud", they are not kidding thes 2 10" Kickers are way louder then I
imagined my 3 & 6 year old tell me to turn it up and scream aloud, my wife
yells at me to lower it. The only down fall and its not that big it does not
come with grill covers. Buy these they are worth money... BUY THEM....


Written By Chris, Tennessee on Sunday, June 01, 2008

Crutchfield Customer Review (What's this?)

These subs hit hard. I have a 1999 Jeep Cherokee and i put 2 of these comp 12s in the back and it shakes the whole car. Been in for just over a month and flawless thus far. No doubt these are worth every penny. If your lookin for hard hitting bump for a reasonable price, look no more, these are your subs. =]

Bump this in your cadillac

Written By Nick, leopold, indiana on Wednesday, January 09, 2008

i have two of these subs in my 1999 cadillac deville in a large ported box hooked up to a 4 channel profile 1040 AB amp (1000 watts) nonbridged. they sound amazing for this price and i would recomend them to anyone. My head unit is a Pioneer 3900 and it is also incredible with many different adjustments availible for the lows and highs. I have two infinity 5 1/4's in the front and two alpine 6by9's in the back and this system booms. The subs are the best part.

GET THIS SUB IF YOU ARE SHORT ON MONEY BUT WANT A GREAT SUB

Best BOOM for your buck!!!

Crutchfield Customer Review (What's this?)

I got two of these bad boys in a custom built box in my Yukon. Their being pushed by a brand new Kicker Amp, the ZX200.2. These subs hit unbelieveably hard and my amp is only halfway up!!! I have loved Kicker for years and would say, in my opinion that Kicker subs are the absolute best you can get for the price at Crutchfield. I got my right after Christmas. I couldn't pass that up. Besides my two Audiobahn 10" subs had been blown, I figured why not?? You simply cannot go wrong getting a Kicker product period!!! Trust me, these babies won't fail you, and you'll be amazed at the bass response and clarity of your music. Plus if your an "Audiophile" like me,..that's your goal anyways.

Get everything you’ll need to enjoy your new Kicker Comp 07C124

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.
These can be useful if you are building a custom box.
