Strong bass adds a whole new dimension to your car's sound system, and Kicker Comp subwoofers give you tremendous bass value for your dollar. You'll hear and feel the power of Kicker bass without feeling like your wallet just got thumped.

Kicker technology at work
Each Comp sub features a flex-resistant polypropylene cone with 360-degree back bracing for hard-hitting lows without distortion. The ribbed foam surround offers long excursion and keeps the cone on target, while double stitching ensures your investment won't come apart at the seams. A tough steel basket provides a reliable foundation for big bass, and extensive venting ensures long-lasting performance that won't break down when the bass gets heavy.

Easy to add to nearly any setup
Kicker's 10C84 8" subwoofer handles up to 100 watts RMS to bring out the depth your music's been missing, and its 4-ohm impedance makes it compatible with just about every amplifier on the market. This versatile sub works well in sealed or ported enclosures, and it's even suitable for free-air applications.

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

Polypropylene Cone: The Kicker Comp subwoofer's super-rigid injection-molded polypropylene cone features 360-degree back bracing to completely eliminate flex and distortion.

Ribbed Foam Surround: The optimized ribbed foam surround allows extended cone excursion for additional bass output and higher SPL. The surround is double-stitched to the cone to add a mechanical fastener to the chemical adhesives. This prevents the cone and surround from separating in the harshest conditions.

Spiralead Tinsel Leads: The Kicker Comp subwoofer features durable Spiralead tinsel leads, which are woven into the woofer's progressive-roll polycotton spider, for added strength and reliability.

Steel Basket with Vented Pole Piece: The Kicker Comp subwoofer features a resilient, steel basket with coil-cooling perimeter venting and a vented pole piece for heat dissipation, so the high-temperature voice coil stays cool.

Speaker Terminals: The spring-loaded, nickel-plated terminals provide solid connections for speaker wire up to 10-gauge. Single banana plugs and pin connectors will also fit.

Rubber Magnet Boot: A black rubber boot covers the outside edge of the magnet structure to improve the cosmetics of the woofer and protect the magnet during installation.

Enclosure Compatibility

Enclosure Versatility: The Kicker Comp subwoofer is versatile, performing in vented or sealed enclosures, and in free-air applications as well.

Sealed Enclosure Applications: A sealed enclosure design gives the smoothest response with increased energy at the lowest frequency between 20 to 30 Hz.

  • Compact (minimum enclosure volume): 0.5 cu/ft
  • SQ (maximum enclosure volume): 1.2 cu/ft

Recommended Vented Box Volume: A vented enclosure design is the choice for loud, high-performance bass for SPL contests.

  • Compact: 0.66 cu/ft with a 1.5" x 8" slot port opening that is 18" in depth
  • SQ: 1.2 cu/ft with a 1.5" x 8" slot port opening that is 12.25" in depth

Note: The SQ enclosures generates a flatter response curve and extends sub-bass response.

Infinite Baffle Mounting: The Kicker Comp subwoofer does not require a sealed or vented enclosure for good bass performance. The Comp subwoofer is designed to also be used as a free-air driver. The infinite baffle mounting method effectively utilizes the rear deck and trunk space of most sedan type vehicles.

I purchased this to upgrade the factory system in my Chrysler Pacifica. I lucked out and found the subwoofer housing for my vehicle so the install was easy pretty much a plug and play. After hooking the subwoofer up I was impressed with the overall sound, you are not going to hear me coming down the block but the tightness and quality of the sound in the car is great. I would recommend this for someone who is looking for quality sound at an affordable price.

Pros: nice sound quality, great price

Cons: style

a top choice to round out my system. i have 4 polk speakers in the doors of my 03' lincoln town car. i needed to add the extra punch that was taxing on my door speakers. i installed this sub in the factory rear deck cut out. almost a perfect fit. a tad small. the sound blends right into my system perfectly. just what i was looking for. i was not looking to shatter my rear window, just sharp clean kick. perfect. an amp for just the sub worked best for me.

Pros: nice clean strong hit.

Cons: not a thing

Originally bought these for a regular cab F350 and they sounded great in the truck!, moved them into an extended cab pickup and they were "okay" they fill out the sound spectrum nicely and they sound good at moderate volumes but once you crank these little guys you can hear them stressin'. All in all another great kicker products, good boom for your buck just dont expect to be blown away from a small driver and sound quality is only moderate.

Pros: great value, attractive

Cons: not the best sound quality

I purchased this subwofer as a direct replacement for a friend/client's older Navigator. Some modification was required to the stock enclosure, but it fit well otherwise. He was pleased with it's performance and having recovered much needed storage space (he was previously using an external 10" sub in a vented enclosure). The performance was comparable as I believe that the stock subwoofer amp is better matched.

Pros: Price. Solid performance. Fit nicely in early Navigator's stock enclosure with minor modification. Reasonably shallow depth.

Cons: Lacks detail. Build quality and performance is not as good as others I've used/installed (JBL, Polk).

I install this in the back dash of a 07 dodge charger. A 8" hole was already there for a factory sub but there was no sub there so I bought this dropped it in and connected a 500 watt amp to it. I can tell it there sound deep on some notes but not as much as expected. I am using it as a free air sub. I tried a box didn't make too much of a difference.

Pros: Loud and Deep, adds a lil to a factory setup

Cons: Can't tell too much if you are trying to run louder after market setup

I bought this sub-woofer to replace the stock sub in my 97 expedition. It fit perfect except the mounting holes didn't line up. I just used some self tapping screws and it was installed in minutes. I can't really say if it sounds way better than the stock sub because it was blown when I bought the vehicle. I am very happy with the sub.

Pros: -Fits perfect in in the back seat on the ground -Sound Quality is crystal clear -Made my sound system sound a hundred times better -Can hit hard for how small it is -Better than most subwoofers

Cons: none, wish i woulda picked this one up the first time.

I installed this in my wifes 2002 chevy Tahoe. It replaced the factory 8" sub that was in it. The sound is great and it thumps nicely using the stock sub box that is already there and the stock amp that is built in. If you do chose to go with the factory sub box, some modification will be needed. As the sub ring is actually bigger than the box opening. This is easily done with a dremel and some time. Once I finished the box mod all went smoothly. It shows great thru the grill on the interior body panel and sounds awesome! Also had to double check on the wiring and the staff were ready to help! Thanks Crutchfield!

Pros: Ease of installation, great sound, & almost perfect fit.

Cons: Non.

Excellent Toyota Avalon JBL Sub Replacement

Just finished replacing the JBL subwoofer in my 2001 Toyota Avalon. I had no intention of spending $50 on a speaker rebuild kit when I could spend $50 on the Kicker. The Crutchfield advisor was absolutely correct in stating that the factory system will be challenged to drive the sub. As another reviewer stated, I'll likely look to install an amp now that I have a speaker in place worth driving. Even with the factory amp, it sounds great. The diameter of the speaker will fit perfectly in the plastic Toyota bracket, you just need to drill 8 holes in the bracket versus the 4 for the original speaker. Toughest part of the installation is trying to pull the plastic bracket out from under the rear deck panel and re-installing it with the new sub mounted. Get yourself a chisel to use as a lever (better than a screwdriver, more surface area on the fulcrum and less likely to damage when prying.....I know, I know, right tool for the right job, but this works) and pry it out and back in. Keep the kids in the house while you're cussing this molded plastic thing. I would have liked to pitch it but you need it to hold on the sub cover/back up light housing.

Enjoy - best $50 I've spent in awhile.

Speaker Fit into my 04 Avalon with very little modification to the current sub bracket. The stock amp does not power it as well as I would like but is is a huge improvement over the blown stock 8". I think I will be looking into an amp next.

Thanks to the guys at Crutchfeild for suggesting this sub. My 98 avalon needed a free air sub because the factory sub was blown out and this did the work couple with my JVC radio. The installation was easy according to the pros who did it and everything was done under an hour.

Pros: Surprisingly Great sound,

Bought the Kicker Comp 8" as a replacement for a factory sub in a 2002 Toyota Avalon with the JBL audio package. The sub either blew or tore and I didn't want to repair. For the price of the Kicker and sound I get out of it I'm glad I did. I wouldn't say the install was easy but I'm no pro and it only took me about an hour.

As for the sound quality, I rated it only 4 stars because I thought I would get a bit more thump out of it. But, I am using it with an infinite baffle (free-air mount) and driving it with probably 30 watts from a factory amp. So I probably can't be too picky.

Pros: Looks cool, sounds good, easy to mount to rear deck

Cons: none

Replaced the stock sub in my 2005 Ford Escape. Mounting depth was a little too deep for the stock enclosure, made a mounting ring out of MDF. Stock enclosure is a little small but adjusting LPF to 50 Hrz and the Slope lets it still sound good. I used the stock amp for a few weeks but it kept clipping due to lack of power. Put in new amp using stock power wires but new amp clipping too. Stock wire too small. Running new 4 gauge solved and now this baby thumps for just a little 8"

Pros: Price, Versatility

Cons: Foam surround

Crutchfield Customer Review (What's this?)

Good Sub for my needs. It is mounted as open air, so the sound isn't perfect, but does what it was designed to do. Mounted in rear deck and causes a rattle in the car at 50% power. Probably should have gone with a box.

Great for 2003 Expedition

Written By Bob, Ohio on Monday, February 07, 2011

Crutchfield Customer Review (What's this?)

Much better sound that the OEM (alpine) sub in my Expedition. It does get deep for an 8"
sub and rounds out the sound nicely.

Application notes: The expedition has custom enclosure that this sub mounted in. The
OEM sub is screwed to the back of this enclosure which makes the enclosure less
deep than it could be right behind the speaker and about 1/4" too short for this speaker.
I ended up melting the back of the surround and pushing it back to make more room
which worked perfect. The OEM was also a dual voice coil, so I hooked all four wires up
to the two connections on this speaker.

very loud subs (i have two of them). you should choose the right amp for them. after two amps they sound amazing.

Get everything you’ll need to enjoy your new Kicker 10C84

We've verified that these enclosures are a good match for this subwoofer.
It's critical to have good wire, and none is included with the sub.
Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
Add a grille and keep your sub safe.
These can be useful if you are building a custom box.
