The heavy steel basket cuts down on unwanted vibrations.

Kicker technology at work

Kicker's 40CWD102 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 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.

Crutchfield Customer Review (What's this?)

This sub arrived today and I just finished installing it inside of a bass tube. I have a small Kicker DX 250 amp pushing this one dual 2 ohm voice coil sub wired with a 4 ohm load. This thing sounds amazing Crutchfield! I could not believe the bass that was continuously coming from my bass tube. If you are looking for a solid 10" sub to compliment your system then look no further. You will not regret this purchase. I could have pushed this sub harder but, my setup is perfect for my musical genre. Thanks again Crutchfield for another great purchase!

Pros: Easy setup and wiring instructions! Amazing bass inside of a dual ported bass tube!

Cons: Absolutely none!

Replaced 2 subs with this dual voice coil one. Hits harder and helps save more space in the Jeep Wrangler. Paired it with a sound ordinance mono block.

Pros: Hits hard and saves space.

Cons: Not free!

This product is awesome

This 10" sub hits really hard! Paired with Sound Ordinance amp, people think I have 2-10"s in a box. Well worth the money, just get a good amp.

Crutchfield Customer Review (What's this?)

Replaced my Lexus GS430 subwoofer for the 2nd time...this speaker was a good fit..however, if you are using only the factory built in amp, use the series wiring over the parallel wiring.

Pros: Good sound for the price...I don't believe you will be disappointed.

Cons: Yet to be determined.

Great sub

This sub is perfect for what I needed. I have it in a sealed custom enclosure for my Jeep cherokee and I couldn't ask for anything more. Plenty of bass for all genres of music. If you are trying to be obnoxious and shake other peoples cars and your neighbors houses then get two but if you just want great bass to improve your cars overall sound quality then one of these is all you need.



awsome sub.

Crutchfield Customer Review (What's this?)

Wasn't trying to blow the trunk off of my car but just wanted to add a little rumble since the car didnt come with speakers in the trunk. These 10's fit perfect with the factory 6X9's that came in the rear doors. Always been a fan of kicker and will soon be upgrading the factory speakers in the doors with kickers. Very happy with my purchase.




great sub from wilburton Oklahoma on 6/28/2013

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.

Kicker is a good brand with a good reputation for big bass. This Kicker 40CWD102 definitely does the trick and it won't hurt your pocket either. It hits all those long deep bass notes with no problem. Sounds great, hits hard, and does all I wanted in a sub. Smart Buy. [ Mark  Nov 02, 2016 ]

Thanks for your question. For information on comparing two or more models 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 and help you make the best choice for your system and your budget. [ Kenny  Jun 23, 2016 ]  Staff
Ohms represent the amount of resistance that the speaker has. If an amp gives 1000 watts at 2ohms, it provides 500 watts at 4ohms, and 250 watts at 8 ohms. This is most important when you are daisy chaining speakers together. It is important to match the impedance of the speakers and insure that your amp can handle the added resistance of the extra speaker. If you have 2 8ohm speakers, you will now have 16ohms of resistance which could potentially burn up your amplifier. Low impedance subs are good for daisy chaining, but work well as stand alone as well. [ Todd  Jan 15, 2015 ]
That is the measure of resistance of the speaker. [ MATT  Jan 14, 2015 ]
