Our take on the Kicker 40CWR102

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.

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.

Overbuilt? More like built just right

Kicker's 40CWR102 10” 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 600 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 450 and 900 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Highlights:

  • 10" subwoofer with dual 2-ohm voice coils
  • injection-molded polypropylene cone
  • rubber surround
  • power handling: 100-600 watts RMS (300 watts per coil)
  • peak power handling: 1,200 watts
  • frequency response: 30-500 Hz
  • sensitivity: 83.6 dB
  • top-mount depth: 5-3/16"
  • sealed box volume: .80 - 3.0 cu. ft.

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.

We stay on top of new products and technologies to help people make informed choices.

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: 0.8 ft³
  • Maximum Enclosure Volume: 3.0 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: 1.25 ft³ with a 10.5" x 2" x 20" slot port
  • Maximum Enclosure Volume: 1.75 ft³ with a 10.5" x 2.5" x 20" slot port

Great 10 inch sub!

Written By RCP, Santa Clarita on Thursday, October 03, 2013
Crutchfield Customer Review (What's this?)
 
The design of this sub is great. It's over built. You can change impedance with a flip of a switch, no extra wires needed. The bass is excellent, outperforms a lot of subs at the same price.
Pros:
Impedance, design, good sound quality bass.
Cons:
None so far.

Hittin hard

Written By Timn, Jacksonville fl on Tuesday, August 20, 2013
Crutchfield Customer Review (What's this?)
 
I purchased two of these subs for my Mazda hatchback. I originally put them in a bandpass box that I had to try and save money instead of buying a new box. Even though the bass was loud it didn't sound all that great. I went ahead and spent the money on a sealed enclosure and now they sound a lot better. The subs hit hard and sound very clear and precise. My windshield wipers and mirrors all vibrate now. I hooked them up to a kicker mono amp. The subs come with a switch that allows you to select the ohm. It's made install confusing for me. When I purchased the subs The description read 2ohm subs, but the switch only allowed me to select 1ohm or 4 ohm. But after adjusting my amp wiring I was set to go. Great buy and I'm happy with them so far.
Pros:
Great price, hit hard, sound great.
Cons:
The ohm switch was a con for me. Had a known about it prior to purchase I would have purchased the 4ohm version that switches from 2 ohm to 8 ohm. But nothing that can't be solved by wiring your amp a certain way.

1 question already asked

I really want to order a pair of these speakers but I am unsure on an amp. Which Kicker amp would power these correctly?....I'm soooo tired of going to local Best Buys and audio shops that offer no help. I currently have a 2002 silverado four door with a down fire box under the rear seat and a Kenwood cd unit. Help please! [ Marc, TX  Jun 07, 2014 ]

  • Thanks for your question. For information on selecting the best amp I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy Staff  Jun 08, 2014 ]
