Brace yourself 

Kicker designed their CompR line of subs for people who love to hear strong bass when their music's playing. Built from the ground up with performance in mind, these subs handle plenty of power to give you the baddest bass available from the legendary Comp line.  

Kicker 40CWR122

Change this subwoofer's impedance with a flick of the built-in switch.

Overbuilt? More like built just right

Kicker's 40CWR122 12” subwoofer comes equipped with a tough, polypropylene cone that stays rigid during intense play sessions so you hear accurate bass. A custom-designed back and top plate give the woofer plenty of room to travel, while the durable rubber surround helps to control cone movement during a heavy workout. This sub uses extensive venting in its heavy steel basket to shrug off heat, so you can count on reliable performance.   

Say hello to system flexibility

This Kicker CompR will handle up to 800 watts RMS so make sure you have an amplifier that'll do it justice. Its dual 2-ohm voice coils give you more wiring options when setting up your system, and this versatile sub works well in sealed or ported enclosures.

To drive this single subwoofer, we recommend a mono amplifier rated between 600 and 1200 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

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.

Features

Dual 2-ohm Voice Coils: This woofer features dual 2-ohm voice coils, offering wiring flexibility. A switch on the speaker terminal allows you to easily change from parallel (the woofer presents a 1-ohm load) to series (the woofer presents a 4-ohm load) wiring for the voice coils.

UniPlate Construction: The woofer features a one-piece UniPlate construction with a vented, extended pole piece and backplate. This unique design provides the following benefits:

  • Optimizes heat transfer efficiency for cooler operation
  • Eliminates erratic magnetic flux in the voice coil gap
  • Releases pressure under the suspension for uniform cone movement
  • Prevents the voice coil from bottoming out, and the resulting damage

Tinsel Leads: CompR subwoofers use Spiralead tinsel-lead technology; the tinsel lead wires are woven into the spider to relieve mechanical stress.

Enclosure Compatibility

Sealed Enclosure Applications: Sealed enclosures provide the most control over a woofer and provide accurate sonic reproduction, making them suitable to all types of music. Kicker recommends sealed enclosures in the following range:

  • Minimum Enclosure Volume: 1.0 ft³
  • Maximum Enclosure Volume: 4.6 ft³

Vented Box: Vented (or ported) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power. Kicker recommends ported enclosures in the following range:

  • Minimum Enclosure Volume: 1.75 ft³ with a 12.5" x 2.5" x 20" slot port
  • Maximum Enclosure Volume: 2.25 ft³ with a 12.5" x 3" x 20.5" slot port

Had a pair of these subs for about a month and they're awesome! fantastic power combined with accurate, crisp bass. My amp is currently only powering them at 450rms each even though they can handle up to 800rms, but they still sound great and accurate. Previously had kenwood subs, and these are much better in every category. Worth the extra money.

Pros: Powerful and accurate.

Cons: Haven't found any yet.

recently bought this speaker a couple days ago. I was pretty impressed when I first hooked it up and have been running this on 4 ohms until this morning. I started reading reviews and decided to switch to 1 ohm and I gotta say that I don't regret buying this kicker. I literally got a back massage and my whole dash in my truck was vibrating after switching to 1 ohm. I'd recommend this to anybody.

Pros: Crazy BASS

Cons: Needs a big amplifier

Crutchfield Customer Review (What's this?)

This is a great sub. Its very powerful, and still very good sound quality at low levels. Both loud and clean (when paired with a compatible amp). Looks real cool in your trunk. And with the impedance switch right on the back installation is extremely simple.

Pros: Sounds great, powerful, built-in impedance switch, looks cool

Cons: None yet

This sub is extremely powerful for a shallow type sub. It hits extremely hard and takes lots of power! I've got a Alpine MRP-M500 powering it and could take more! It literally makes your hair tingle! I have it a kicker ported enclosure. Super impressed! Good value as well for a mid level sub! Be sure to use a powerful enough amp or you could be disappointed.

Pros: Powerful sub!

Cons: None

For the longest time I wanted alpine type r 12's just never had the money and then I went to a local place and they told me these were the best for the money, and let me tell you they weren't lying. My little brother sat down in my backseat and said it was the best back massage ever. I can't say enough how happy I am with these subs.

Pros: Hit super hard on every frequency, turns people's heads, just all around great quality

Cons: Non

I gave 5 stars because they deserve it. First of all let me just say "WOW" These subs really do what they say. The bass comes out clean and crisp and when the lows really kick in thats when u really feel the shaking. If ur sitting in the back seat your back literally gets a pounding from these speakers. But its all good for me. Kicker came out with some bad-ass subs with these ones. Installation was a piece of cake and u have ur wiring options at the flick of a switch.

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.
These can be useful if you are building a custom box.
Add a grille and keep your sub safe.

1 question already asked

you cant, each coil is 2 ohm but you have to use both. if you get a dual 4ohm then the settings choices will be 2ohm and 8ohm [ Thomas  Jul 21, 2014 ]
Not positive, but putting the setting on 4 ohm level; then put a 4 ohm resistor across speaker wire to each speaker. When two resistors of the same value are parallel together, the resistance becomes half. So radio output will see a total of 4 ohms, and speaker will split the load, to have 2 ohm value on it. My best guess. U may have to use multiple resistors to add up to 4 ohms, like 4- one ohms, 2- two ohms, results will be close enough. [ JOHN  Jul 20, 2014 ]
