Our take on the Kicker 40CWS82

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 CompS 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 40CWS82 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.

2-ohm impedance for more power

This sub handles 200 watts RMS to bring out the depth your music's been missing, and its 2-ohm impedance brings out max power from your mono amp. This versatile sub works well in sealed or ported enclosures, and it's even suitable for free-air applications.

Subwoofer Features
Enclosure Compatibility

Subwoofer Features

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.

Replacement for 2001 Tahoe Factory Sub

Written By RussellK, Burnet, TX on Saturday, May 03, 2014
Crutchfield Customer Review (What's this?)
 
I used this for a direct replacement for a 2001 Tahoe with Factory Sub/Non-Bose system. Although Crutchfield states that they don't have a direct replacement other than the self powered replacement housing for this vehicle, I followed the recommendations of a couple of forums and bought this sub. The only modification that was required to the factory housing was drilling 8 pilot holes for the mounting screws.
Pros:
Great sound, direct fit with no real modifications to the factory housing.
Cons:
None to date...

Not a free air sub

Written By Bill Mild, Kansas City, MO on Friday, December 06, 2013
Crutchfield Customer Review (What's this?)
 
I have a 1998 Lexus LS400 that had a broken stock Pioneer sub in the rear seat shelf. I researched a lot of open air subs and I saw this one was supposed to fit the bill. There is some custom work that is required to get this sub to fix so get the dremel ready if you are looking to purchase this for your LS. First the stock sub you need to cut off the mounting ring. After that has been completed you can them epoxy and screw the mounting ring to the new Kicker sub. This will allow the sub to be a drop in replacement in the car.

I'm not sure if this Kicker Sub is really a free air design. It doesn't seem to work at all ranges very well. Some songs the sub you can really tell is there, other songs it doesn't add much. I am using the stock amp which might be a cause of this as well. Overall a well constructed product, but if you are looking for an open air sub I recommend a different one.
Pros:
Good build quality, 2 OHM SVC(hard to find).
Cons:
Not really a great free air sub.

Crutchfield Customer Review (What's this?)
 
Needed a replacement 8 inch 2 ohm sub for my 2001 tahoe. non bose with factory sub. I called Crutchfield and the advisor I talk to said they had no sub that woud fit and if it did that it would not work with my factory radio. told me to call the dealer for replacement . Dealer has no replacement now. Kept checking the reviews and found this sub. It fit right in the factory box and works great. The only problem was a lot ot rattling in the factory sealed box. I had to drill about 5 or 6 one inch holes to vent the enclouser to stop the rattling. Sounds pretty good now.
Pros:
fit right in the factory enclouser. Sounds great for an 8 inch sub.
Cons:
Very Dissappointed in the Crutchfield advisor program.

What kind of amp would you suggest for this woofer. I plan on getting two of these? I'd like to keep the amp kicker as well [ Aaron  Feb 01, 2014 ]
2 answers
  • I've been in the car audio business for a long time and probably would not choose this driver. but a customer brought it to me with a rather inexpensive amplifier and I must say it was absolutely impressive! It took very little power and gave substantial bass output, even at 40HZ. It's a good inexpensive subwoofer. [ CARLFRED A   Feb 03, 2014 ]
  • I replaced the factory sub with this one. Using the factory amp in my truck, so I don't have much of an opinion on amp selection. However, using just my stock system I have been thoroughly impressed by the speakers performance. [ CHRISTOPHER   Feb 02, 2014 ]
