Kicker technology at work

Kicker's 40CWD82 8" 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 200 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 150 and 300 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

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: 0.5 ft³
  • Maximum enclosure volume: 1.2 ft³

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

  • Minimum enclosure volume: 0.66 ft³ with a 1.5" x 8" slot port opening that is 18" deep
  • Maximum enclosure volume: 1.2 ft³ with a 1.5" x 8" slot port opening that is 12.25" 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.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
i want to upgrade existing factory sub [ LINDA S  Jan 25, 2017 ]
A
Needed a replacement for a blown/rotten subwoofer in my 2003 Toyota 4Runner. The factory amp may have difficulty driving it with its low sensitivity, however, it should fit just right and it matches all other important specs from the original subwoofer. [ Dylan  Nov 15, 2016 ]
A
Good price and right replacement for my vehicle. [ Timothy R.  Nov 09, 2016 ]
A
I've always like the sound quality from Kicker products. Great sound without busting seams in the wallet. [ Joshua  Nov 03, 2016 ]

Fits directly into the OEM sub location, and was looking for a little more bass than OEM. [ Alex  Jul 21, 2016 ]

spec my box best [ barry  Mar 19, 2016 ]
A
My 2015 Chrysler 200C came with the 10 speaker Alpine Premium Sound. Now! I am a bass head, and that Alpine sub is not cutting it. I own a Kicker Comp 8 already, and am very pleased with it inside my Logitech Z906 computer system. I cannot use this sub due to it not being DVC and 2Ohms. I can't wait to see how this subwoofer sounds, have heard excellent reviews on it so far. [ Cody  Mar 12, 2016 ]
A
for my listing ear the 2ohm sound I lot better to me than the 4ohm [ Gregory  Mar 09, 2016 ]
A
I care about a good quality sound but not looking to annoy the neighbors. I went high and purchased Focal Integration speakers, and went for low price on this little sub to round out the sound. [ Michael  Feb 26, 2016 ]
A
I only buy Kickers. Kicker brands are for the best. Quality and last longer. [ Jaime  Feb 05, 2016 ]
A
It has great reviews, and its specifications met my needs. [ Carlos  Dec 15, 2015 ]

Q
Does my factory Bose amp in my 2001 Yukon XL have enough power to push this sub?
[ Joe  Apr 17, 2016 ]
3 answers
A
Short answer is probably not. Quick research on the Yukon XL Bose system says the factory sub is an 8" 2 ohm single voice coil driver. The CompD is a dual 2 ohm coil. What that means is this sub can be configured either as 2 channels at 2 ohms, 1 channel at 4 ohms (series connection) or 1 channel at 1 ohm (parallel connection). I also don't know the mounting depth available. You might be better off with the CompRT 8" 2 ohm shallow mount model 43CWRT82. If you have the available mounting depth then the CompR or CompS line might work out OK.
[ Richard  Apr 19, 2016 ]
A
It really depends on the capability of that amp. You need to know its specs and then tell the techs at crutchfield. You could be underpowered or have the wrong olms and then it's no good.
[ Matthew  Apr 18, 2016 ]
A
M not sure, you have to check the ohms and what RMS the bose amp puts out. Crutchfield should have a vehicle match with speaker compatability.

Will i need a box?

Hello Aaron, I would say yes you will need a box. This kicker is a sub woofer which needs to be mounted in a box to achieve the strong bass. Mike
[ MICHAEL A  May 07, 2014 ]
A
I believe you can use it for free air applications, but I built a sealed box for mine for about $50 and it works very well. It is only an 8" so it does not hit the very low notes how you might want it to. I use it in my 2003 Jeep Wrangler and I am very happy with it. Even for not hitting the low notes it does more than you expect.
[ KODY  Apr 30, 2014 ]
A
Depends on your setup. In my g35 was a free air sub so I didn't need a box. It just sat on top on the rear deck being screwed down. Thumps pretty nice without the box also. If you have a box that you want to put it in it would be fine.
[ WILLIAM  Apr 30, 2014 ]
A
You won't need a box if you don't want one. These subs sound great in a free air setup as well.
[ MARCUS  Apr 29, 2014 ]
A
Yes
[ DONNIE L  Apr 29, 2014 ]
A
It is a free air subwoofer. They can be used with out a box. Mine was used in the deck lid going into my trunk.
[ JASON G  Apr 29, 2014 ]
A
You will need an enclosure of some sort if you're trying to feel the frequencies as well as hear it.
[ rik  Apr 29, 2014 ]
A
No. My stereo guy installed without a box to replace the factory free-air woofer.
[ LAWRENCE E  Apr 29, 2014 ]
A
That's kind of a no brainer
[ PATRICIA  Apr 29, 2014 ]
