A match made in heaven...or Oklahoma

Kicker's 40TCWS102 loaded enclosure puts a thumping 10" subwoofer behind the seat of a truck or in any vehicle that's low on space. The rugged ported box was designed specifically for the subwoofer, so you can count on getting maximum performance, no matter what kind of tunes you enjoy.

The specially designed port gives you more bass without sounding sloppy.

Hard-hitting CompS sub

The 10" CompS sub 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 extensive venting ensures long-lasting performance that won't break down when the bass gets heavy.

Heavy-duty enclosure

Sturdy medium-density fiberboard ensures long-lasting performance from the enclosure, and the special-design side port delivers more bass without getting sloppy. The enclosure's 2-ohm impedance draws maximum power from your mono amplifier.

Good bass for tight spaces

Ernesto from Yuma, Az. on 11/9/2016

Crutchfield Customer Review (What's this?)

Great speaker for tight spaces like in my 1991 F350 crew cab. I was not expecting to get good bass out of a such a slim speaker box so i only bought one, but im so impressed with the sound that im buying a second one so I can have the pair.

Pros: Slim and good tight bass

Cons: Nothing bad to say. All good.

Crutchfield Customer Review (What's this?)

I went with this sub to save space in my forester. It provides a good amount of bass to fill out the lows. It is not rattling the windows yet, but I am sure it could when tested out. VERY VERY happy and would recommend to anyone!

Pros: great bang for buck; good bass

Cons: none!

Crutchfield Customer Review (What's this?)

This subwoofer is small, but can put out some good bass; It has the low end sound I was looking for. I paired it with a Clarion 5 channel amplifier (XC2510). I wish I would have bought a separate amp for the subwoofer. I also wish the subwoofer would have came with a grill to protect the speaker.

Pros: -Small footprint, doesn't take too much space in trunk -Great low end sound -Price was reasonable for box and speaker

Cons: no grill to protect subwoofer

Should have bought sooner!

Crutchfield Customer Review (What's this?)

Scratch and dent product. Came out the box in practically new condition. Imported enclosure gave me the low end bass I was looking for while fitting behind my bench seat in my single cab truck. Sounds amazing. Great job Kicker!

Pros: Small package. Under 8" at bottom width. Fits just about anywhere. Exceptional bass out this enclosure/ woofer combo.

Cons: None!

Works great

Denver from California on 4/8/2016

Crutchfield Customer Review (What's this?)

Got this from the scratch and dent clearance section, did not see any scratches or dents. Works great with plenty of bass for my truck, I have tested it out with rap to see what it would do but normally listen to country and rock. This fills out the sound in my truck and gives the door speakers a break because I can use the pioneer head units high pass filter so the sub is the only component pushing the low frequencies.

Pros: Clean sound, good price, lots of bass

Cons: No protection for the sub, speaker is exposed in the front

Amazing BASS!

Jeff from Georgia on 1/4/2016

Crutchfield Customer Review (What's this?)

I was looking for bass for my son's first truck. Had an idea of what i wanted but ended up chatting with the Crutchfield support team to get their input. Boy was i glad i did!! Today's speakers and amps put out a lot more power than the old days. As recommended i went with (1) 10" Kicker Sub w/ a 300 watt amp. Yes, i said 300 watts. I was pretty skeptical...but Crutchfield insisited it was enough. And boy was it. This sub & amp combo puts out some mean bass. It hits hard on the rock songs and super low on the bass for rap songs. Very pleased!!! Thanks Crutchfield support!

Pros: Compact. Leaves plenty of room for other stuff.

Cons: Wish it came with the grill to protect it. I'll need to order one of those.

awsome bass response

dm from Florida on 1/2/2016

Crutchfield Customer Review (What's this?)

Also purchased the Kicker 12CX300 amp...which is a perfect combo. Bass is loud and responsive. box is a quality build as well. In past setups I have used Infinity Bass links, Bazooka Bass Tube and similar style boxes using Rockford Fosgate and Pioneer subs. This Kicker set up far exceeds all past installs with better sounding bass, loudness and build. I highly recommend. it is currently under the back seat of a F150 super crew and still using factory head. unit. Perfect for Hip Hop Rock Alterative Reggae and Country music..

Pros: Sound quality and construction

Cons: none so far

Great product for a great price!

This subwoofer was perfect for the purpose I bought if for. This was for a teenager who has a subcompact car. I liked that the subwoofer came in the enclosure and was ready to hook-up.



Sub for 94 F-150 Reg cab

Reef G. from Charlotte, NC on 12/18/2015

Crutchfield Customer Review (What's this?)

This (scratch & dent) sub addition was the perfect bang for the buck. I was just wanting some extra punch to add to my Sony Mex 5100 bluetooth stereo. It fits perfectly behind my seat with the seat moved all the way back for my 6'2" frame. Its paired to an kicker 300 watt mono block amp using the 2 ohm feature. The sub is still in its break in period but I can already hear the improvement. Take the time to tune it to your stereo and you'll enjoy a lot of punch with some lows from this quality sub box.

Pros: Great build quality, Nice looking box. Good speaker terminals. Still looked new for a scratch and dent sale product with a new product warranty included.

Cons: None

Perfect size, nice price and great sound.

Lyle from Nevada on 12/10/2015

Crutchfield Customer Review (What's this?)

This is a very nice, perfectly sized box for my pickup truck. Has really good sound as well. I appreciate the attention to detail as well as the quality of craftsmanship. This is my first time buying Kicker, but it definitely won't be my last! In addition to all of the above, the price is very nice as well.

Pros: Quality. Size. Sound. Plus quality. And size. And sound.

Cons: None thus far. I can't imagine this will change either.


Wayne from Colorado on 11/25/2015

Crutchfield Customer Review (What's this?)

Installed into my 86 Ford 150 when my stereo gave out. Put in new head unit, door speakers and THIS ... just 1 did it. Nice clean base.

Pros: Went well with the 300.1 Kicker amp.

Cons: NONE

Kicker Kicks

Michael from California on 8/21/2015

Crutchfield Customer Review (What's this?)

This speaker package really throws out incredible bass. I have it paired with a mono 250 amp by Alpine. I love it. I didn't know this but in the fine print on the speaker it talks about a break in period on Kicker subs. This is accurate, at first I was slightly disappointed with the sub, but I read about the break in and sure enough once the break in period was near it's end the sub's performance was night and day. Sound amazing.

Pros: Everything

Cons: none

Great sound for the price

Chris H from Florida on 8/10/2015

Crutchfield Customer Review (What's this?)

Sounds great. Bought this for my stepson's truck and wired to a Picasso Nano. Durable construction, easy installation and looks great with the gray interior of the truck. I'm thinking about getting one for my truck.

Pros: Sound, cost


Great sub!

Pros: Performance, clearing and price

Cons: None

Good deal

Jeff from Alabama on 6/22/2015

Crutchfield Customer Review (What's this?)

Good overall value. Well made and the profile is great. Fits well under driver side rear seat of my 2014 Silverado crew cab. Even with a full RMS power amp, you won't be rattling the neighbors windows but the bass production is still impressive for what it is. Has good, boomy bass when you want some dance jams but has really good punch from bass drum for rock.

Pros: Great price, great sound, good build quality.

Cons: Wish it could be just a tad smaller to fully hide under my seat, but this is a personal problem, not a product one!

I am awe struck by the sound of SUB, listening to the awesome bass of Skynyrd's "One More From the Road" live version of "Workin for MCA", proved this product meets and exceeds all expectations. You will be shocked at the continuity and clarity of this product. Do not put this purchase off as I did.

Great sub!

Dave from Massachusetts on 2/17/2015

Crutchfield Customer Review (What's this?)

Having recently upgraded the factory radio in my 2012 Chevy Express cargo van to a Kenwood DPX500BT, I took advantage of a special Crutchfield was running at the time for an add-on set of 6.5" full range speakers to go along with the new head unit. Just like a domino effect, the excitement of having new features in the head unit then lead to better sound in the doors, and eventually to "well if I'm going to replace the factory radio and factory speakers, I should make sure the low end tastes good too." With a partition wall in the van between the cab and cargo space, I had a closed off front area that I knew would benefit acoustically from a sub, even if it's position would be relatively close to the driver's ear. The sub now sits behind the passenger seat, and fits like a glove. Paired with an Alpine MRV-M250, and utilizing the elaborate EQ options on both the amp and the Kenwood unit, this sub sounds really great and complements the full range of the system- with a surprisingly powerful output, to boot. Nice low end, and the ported design gives the sub a just-right tone for the majority of dance and hip hop music I tend to listen to most.

Pros: Great sound, clear output, durable box build, perfectly sized enclosure


enclosed comp s 10

Scott from Florida on 1/28/2015

Crutchfield Customer Review (What's this?)

This was a perfect fit for my 2003 Ram 1500 regular cab. I didn't have to remove the storage tray and it fits perfectly behind the drivers seat. The range of this sub is great. From 40hz-200hz is nice and tight, as it dips below 40hz it becomes a little flat, but if you need lower that 40hz, you should have at least a 12" preferably a 15" for those ranges(in a deeper box, made for a trunk). The power is plenty for a small cab, it really fills up the cab with quality bass. Kicker has always produced a quality sub, but in the past I went with RF Punch 12's and Orion XTR 10's in the 80's and 90's. Now that I own a single Kicker 10, I will rate this sub very high. For anybody space challenged needing a good quality, pre-fabed box, with nice tight bass, this would be an excellent choice. Just don't expect this to take your breath away or vibrate the car next to you. This sub and enclosure was not designed for that. Well done Kicker, and thanks again Crutchfield for selling a great sub!

Pros: Nice tight bass, a well built box. Perfect for space challenged vehicles.

Cons: If I had to be picky, I would have liked the top of the speaker box to say "Kicker" in black, not bright yellow...but that's me being picky.

best SW ever

Great Box

Jimmy from Jacksonville, NC on 9/11/2014

Crutchfield Customer Review (What's this?)

Great box, I am not looking to make hair fly or flex windshields, so this was a great sub/box for the price. The sound is great.

Pros: Great sound Small footprint, fit behind back seat in tacoma -had to remove the plastic storage bin.

Cons: none at this time.

Great bang for the buck

Ben from New Mexico on 8/15/2014

Crutchfield Customer Review (What's this?)

Installed in a 99 crew cab f-250 installed perfectly behind rear seat. Sounds good shakes the rear view mirror paired with SO 1350 amp. What can you say even the lower end Kicker still sounds great and just the right amount bass with a reasonable price.

Pros: Great value great sound

Cons: None

Awesomeness on a budget

Vcpbp101 from San Antonio, TX on 1/13/2014

Crutchfield Customer Review (What's this?)

Perfect fit for my 2005 Chevy Colorado Reg Cab. It sounds great and is affordable. And it's Kicker...enough said.

Pros: It comes with a factory box designed for the sub so it's plug and play. The bass is perfect for a little truck.

Cons: none so far

Great sub sounds great fits behind the rear seat perfect I have alpine 500 watt amp with the gain 3/4 up and the bass is just right.

Pros: Size and price

Cons: None

Good bang for the buck

Ali from Lexington, KY on 8/25/2013

A good addition to the car audio system of someone who is not an audiophile and just wants some shaking, rattling and vibrating. It reproduces nothing below 30Hz, which for rap, hip-hop and some electronic music listeners might be a bad point. The base out of this tiny little 10" subwoofer is about hard bass sounds, nothing soft, which for some is good and for others is not.

Pros: Good value. Nice design.

Cons: Sound quality is above average. Shallow box depth makes it easy to tip over - must be secured to the floor with the provided metal tabs.

Good bass for cheap

Sonomadriver from Houston, TX on 8/18/2013

I bought this for my 1992 GMC Sonoma. It fit perfectly behind the rear seat and is being powered by the sub channel of my Arc Audio xdi803. It's getting about 400 watts and it seriously RIPS!! I was very surprised at the output of this box, can't stop cranking it!

Pros: Looks great Well built LOUD!

Cons: It's just a Comp, so you can't dump a ton of power to it


Hands-on research

Product Research


Speaker Terminals: The spring post terminals are mounted on the left side of the enclosure and will accept pin connectors, single or dual banana plugs, or bare wire up to 10 gauge.

Woofers: The Kicker 40TCWS102 enclosure uses one 10" CompS subwoofer, wired to present a 2Ω 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.

Break-in Period: Due to the complex nature of Kicker CompS speakers, they require a break-in period in order to produce optimum low-bass response. The suspension system is very stiff out-of-the-box. Approximately two weeks of daily playing will allow the suspension to break-in and reach its optimum equilibrium. Once broken-in, the subwoofer will exhibit stronger bass performance, smoother response, and greater low-bass extension.

I really don't know. My subwoofer is behind my seat in a Chevy pickup. You can lay it on its back and it will still sound good. That speaker box is not that big so it might fit. [ SHANNON  May 31, 2016 ]
Thanks for your question. For information on selecting the best match for your subs 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 models and help you make the best choice for your system. [ Kenny  Dec 26, 2015 ]  Staff
I'm using a Kicker amp. CX300 mono block. It pounds the speaker really good. In fax it broke the speaker wire connections inside the sub woofer box where they had soldered the speaker wires. I just put regular speaker connections back on and it works great. [ SHANNON  Dec 07, 2015 ]
I am Currently running a 300 watt Rorkford Fosgate amp @ 2 Ohms to this sub, its more than enough to power it and produce a good sound [ John  Dec 07, 2015 ]
I paired it with a Kicker CX 300.1 and love it. [ Joey  Dec 07, 2015 ]

Should be fine. All wire connections are located on the side of the box. [ Jason Michael  Jan 15, 2015 ]
Definitely buy a grill to cover the woofer. The only potential issue with a flat mount is smaller debris having an easier time making its way through the grill. I leave mine free and with slack in the speaker wire so I can reconfigure it based on what I'm stuffing in the back. Hope that helps [ NASH  Jan 14, 2015 ]
Yes it is , there's no problem with that it works fine but you need to put a cover on it to protect the speaker [ SAMUEL  Jan 14, 2015 ]
Should be just fine. [ Benjamin  Jan 14, 2015 ]
I have mine flat in the trunk of my 91 towncar. It's been working great for just over a year now. [ ANDREW  Jan 14, 2015 ]
