Our take on the Kicker 40CWD122

by John Pollard
Kicker

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.

Legendary bass, awesome price

If you're looking to add some boom to your car's sound system, Kicker's CompD line will get your car shaking without draining your wallet. These subs are the latest in the legendary Kicker Comp line that started in 1986, with a proven pedigree when it comes to delivering powerful bass.

Kicker technology at work

Kicker's 40CWD122 12" subwoofer features a flex-resistant polypropylene cone for hard-hitting lows without distortion, while the ribbed foam surround promotes long excursion and helps to keep the cone on target. The sub's steel basket provides a reliable foundation for big bass, and its extensive venting ensures long-lasting performance that won't break down when the bass gets heavy.

Easy to add to nearly any setup

This sub handles up to 300 watts RMS to bring out the depth your music's been missing, and its dual 2-ohm voice coils give you more wiring options when setting up your system. This versatile sub works well in sealed or ported enclosures, and it's even suitable for free-air applications. 

To drive this single subwoofer, we recommend a mono amplifier rated between 225 and 450 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

  • 12" subwoofer with dual 2-ohm voice coils
  • injection-molded polypropylene cone
  • ribbed foam surround
  • suitable for free-air use
  • power handling: 50-300 watts RMS (150 watts per coil)

Subwoofer Features
Enclosure Compatibility

Subwoofer Features

Dual Voice Coils: For increased system flexibility, the woofer has two 2Ω voice coils. When the voice coils are wired in parallel, the woofer presents a 1Ω load. When wired in series, the woofer presents a 4Ω load.

Ribbed Surround: The optimized ribbed polyurethane helps eliminate flex and distortion.

Spiralead Tinsel Leads: The durable Spiralead tinsel leads are woven into the woofer's spider, for added strength and reliability.

Steel Basket with Vented Pole Piece: The steel basket's vented pole piece and Kicker's Quad Venting slots contribute to the woofers' efficient cooling and durability.

Speaker Terminals: Each speaker terminal has two 0.25" push-on terminals (crimp-on quick slides included).

Enclosure Compatibility

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

Sealed Enclosures: A sealed enclosure design offers the smoothest response, with increased energy at the lowest frequencies (between 20 to 30 Hz).

  • Minimum enclosure volume: 1.25ft³
  • Maximum enclosure volume: 3.5 ft³

Ported Enclosures: A ported (vented) enclosure design is typically more efficient than a sealed enclosure.

  • Minimum enclosure volume: 1.75 ft³ with a 2" x 12.5" slot port opening that is 16" deep
  • Maximum enclosure volume: 2.25 ft³ with a 2" x 12.5" slot port opening that is 16.375" deep

Infinite Baffle Mounting: The Kicker Comp subwoofers are also designed to be used as free-air drivers. The infinite baffle mounting method effectively utilizes the trunk of a sedan as the enclosure.

"Kick"-Butt Subs!

Written By Alex, NY on Wednesday, September 24, 2014
Crutchfield Customer Review (What's this?)
 
Just installed two of these babies into a custom sub box I made within a few days. Custom porting to for a 30Hz frequency. All powered by a Kicker DX 500.1 amp. First day used, to just break in and already these things sound great. From electronic like Dubstep and House, to heavy metal/metalcore/ect. (anything with kick-drums and other percussions), two of these really punch you right in the chest when that note hits. They are also built like a tank, the outer case seems like really thick cast (or pot metal maybe?) steel, the magnet is gigantic and the cone itself is thick and rigid. The only thing that's a bit questionable is the foam connecting the cone to the frame, it seems stronger than the deck and door Kicker's that I have in my vehicle, but it still seems easy to puncture. So just be careful with that. I guess they can't make it any stronger so it can extrude with the cone.

First set of subs I've ever wired and placed into a car! Nice easy install. Gonna' kick for a long time!
Pros:
Sturdy, great value, great sound. Very punchy when tuned right, if that's how you want to tune them (rather than rumble-y). They may be a bit on the cheap end, for the price, but they can definitely compete in small competitions. They'll also handle quite a bit of power. And they're loud and I barely pushed them to 50%. Then again, that also has to do with the amp; 250 watts to each in my set-up. If you're looking for a mid end woofer that can rival up to a high end one, buy these.
Cons:
They didn't come with a protective grill to put over the cone and edge-foam like my deck and door Kicker speakers, but that's okay I'll do something custom for 'em. The foam connecting the cone to the case seems like it can be punctured/damaged a bit easily. But maybe that's like that will all woofers/speakers so the cone can extrude ?
