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.

The heavy steel basket cuts down on unwanted vibrations.

Kicker technology at work

Kicker's 40CWD104 10" 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 4-ohm voice coils make it easy to connect to a mono amplifier. 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 2 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.

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: 1.0 ft³
  • Maximum enclosure volume: 2.4 ft³

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

  • Minimum enclosure volume: 1.25 ft³ with a 1.5" x 10.5" slot port opening that is 14.5" deep
  • Maximum enclosure volume: 1.75 ft³ with a 1.5" x 10.5" slot port opening that is 13.25" 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.

Overall, it's tough to beat the CompD series for bang-for-the-buck. I put 2 of these in individual sealed enclosures in my extended cab ranger, pushing them with the 300.1 kicker amp, and they're awesome. Sounds like they could take more power since I'm only running 150W rms, but they're very responsive. Great sound for the price.

Pros: price, tight sound response

Cons: they make you want more power and more subs

Not for all vehicles

This may work great for some but for me it was a big let down. I replaced my stock sub out of my 06 350z convertible. Just didn't sound good at all. may sound better in a box. I when with the JL Audio CP108LG-W3v3. A little more but well worth it. The amp that I'm using is the JL Audio XD700/5v2

Pros: looks good

Nice free air sub

Replaced OEM Mark Levinson 10" sub in a Lexus GS300. It sounds fine with the stock amplifier, and I am sure it is not pushed anywhere near its capability. Good, clean sound and works well in a free air application.

Pros: Inexpensive, reasonable quality, and good sound.

Cons: The included wiring diagram was difficult to interpret, but Crutchfield's online resources helped.

Great

This kicker subwoofer fitted nicely in the factory location of the Bose sub that came with my 350Z. Wired to the Kicker 12CX300.1 amp, this sub hits hard, it's powerful and very loud. Very easy to install and clean looking. I recommend it to any one wanting to upgrade their sound system from the factory. I've already installed a LCD display Head Unit that has subwoofer controls and allows me all kinds of control over the system than the crappy factory Bose system.

Pros: Loud, clean, and very powerful!!

Cons: None!

I was a little hesitant on buying subwoofer. After speaking with a tech advisor, I decided to buy this and paired it with a kicker CX300.1 amplifier. I have a medium size car and put one of these in a vented box and WOW!! This subwoofer hits hard and is super loud! I have had a couple friends ask me what I have in the trunk and are blown away when I tell them its only one 10" subwoofer. The only thing I would change is the connection type to the coils. They are kind of hard to get to and require the use of connectors. Not that big of deal. Don't think twice about buying this!

Pros: loud. hard-hitting. clean. heavy. durable

Cons: none
