The Kenwood KFC-WS12 12" shallow-mount "flat" subwoofer makes it a breeze to find a space for bass in those hard-to-fit areas of your vehicle. Its low-profile design means it thrives in compact enclosures, but don't be fooled by this sub's small stature — its rugged construction and advanced materials make it a low-end dynamo.

The glass-fiber cone offers exceptional strength without added heft that can slow speaker response, and the cone's honeycomb design lets the woofer deliver hard-hitting bass that's accurate and musical. The thick rubber surround maintains control over the cone, minimizing distortion caused by resonance.

Kenwood uses plenty of venting in the tough die-cast aluminum basket, so heat is shunted away from the internal works. Silver-plated push terminals offer convenient connections and provide excellent signal transfer.

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.

Features

Woofer: The Kenwood KFC-WS12 Flat Subwoofer features a glass-fiber honeycomb cone woofer.

Smooth Linear Surround: The woofer utilizes a smooth linear rubber surround for added durability and better bass performance.

Super Linear Spider: The woofer features a Super Linear Spider design. In this design, the Spider roll gradually becomes higher towards the center enabling this area to withstand more stress with less stretching. This design transfers up and down movement outward to reduce stretching the center area of the woofer. Because the spider's outward portion has more surface area to better dissipate stress from the center, this helps to reduce mechanical damage during increased excursion and enables the subwoofer to withstand more power.

Aluminum Die-Cast Basket: The KFC-WS12 utilizes an aluminum die-cast basket for added rigidity and support.

Spring Post Assembly: The woofer features a compression input terminal assembly that will accept up to 10-gauge speaker wire.

Rubber Trim-Ring: The KFC-WS12 comes with a rubber trim-ring which hides the woofer's screw-holes for a neat, professional looking install.

Enclosure Compatibility

Sealed Box Volume: The sealed box size recommended by Kenwood is 0.8 cu/ft.

Vented Box Volume: The vented box size recommended by Kenwood is 0.8 cu/ft with a 3" (diameter) x 14" (long) port.

Its a pretty awesome sub. I got it hooked to a 1000 watt Kenwood amp and an alpine head unit and just got some infinity reference components to even out the highs and bass. Overall would highly recommend this sub to any one lookin to add some bass to a tight space.

This is a very nice woofer. Be aware, if you order the "outlet" version, as I did, it may not come with any instructions, mounting hardware, or the ring that hides the screws. This was not a problem in my case as I have lots of screws, the instructions are on the internet, and I am using it in a down-firing config. so it is not visible. Which is a shame, as the woven silver fiberglass is quite pretty. It is a well-made unit, with a sturdy basket and other heavy-duty components. This unit has respectable Xmax numbers and a low Vas which allows for small boxes. Kenwood recommends a 0.8 cubic foot box, but my calculations showed that would result in a boomy response. I made the box as big as the back seat would allow (~1 cu ft.) with lots of fiberglass and it still sounds a bit taunt but still quite nice. Recommended, especially for the price.

Pros: shallow profile good looks good excursion well built low fs low Vas means smaller box

Cons: high Qts means bigger box "outlet" means no hardware

Decent Sub

I bought one of these subs paired with the Sound Ordnance (SO) M-1350 amp, and SO BB12-T enclosure. I did not want to spend a lot of money as I was installing into my secondary vehicle (regular cab GMC Sierra.) The sound quality is decent. However, not the best sounding bass I have heard. I think that the sound is improving as the sub breaks in. I have only had the setup for a few days. I certainly enjoy driving my truck more now so it is a win.

The M-1350 amp seems to be plenty enough power for the sub. You can distort the sub when cranking the gain on the amp. The price of the above setup from Crutchfield was great.

I would recommend this sub to anyone who doesn't need the "absolute" best and has a vehicle where space is tight.

Keep in mind that this is my first experience with a shallow mount sub so I have nothing else (in it's class) to compare it to.

Pros: Shallow sub for tight spaces. Good looking sub. Price

Cons: seems to distort easily.

Written By A.B., Culpeper,VA on Saturday, June 11, 2011

I have have this installed in a Ford '05 crew cab, pushed by an alpine m500 and it sounds great. Tight fit but it fit without the bars on it. Great price for what you get.

Best hard hitting sub for truck

Written By Steve, Tulsa, OK on Monday, May 30, 2011

Crutchfield Customer Review (What's this?)

This sub hits harder than any sub I have previously Owned. The benefit of this sub is its shallow depth which is perfect for my F-250. It fits snug behind the seat which is exactly what the sound ordanance box was made for. Pushed by my Alpine MRP-M500 and paired with Alpine S Components and 6x9's, it is by far the best complete sound system I have ever heard. I've had several SUV's with pairs of Dual 12" subs, and sony 10" subs, and this single 12" Kenwood Sub is by far the best sounding sub.

Big sub in a small package

Written By EricB, Burlington, NC on Saturday, February 05, 2011

Crutchfield Customer Review (What's this?)

I have to say the shallow mount subs put out as much thump as the normal counter
part. The Kenwood KFC-WS12 can fit in lots of locations, but still sounds great.
I installed this in my 1982 Camaro where space is at a minimum to begin with.
You can put 2 of these in the well of the trunk and still have room for your
T-tops. The power handling is excellent so far, I'm pushing this with a Kicker
ZX amp, and it sounds sweet. The KFC-WS12 really balanced out the low end of my
system.

awesome

Written By jazzy, Detroit on Saturday, January 29, 2011

Crutchfield Customer Review (What's this?)

Im running this sub with an Alpine MRP-500 amp around 300 watts says the sub will run
350 and 1400 for a brief peak, using this sub in the free box it came in and its sealed.
Sounds really good for the money and I gaind more space in my trunk. hits harded and
plays louder than my 2 twelve inch kicker comps and calfornia AP1040 amp running
bridged at 225 watts. I want a shallow mount sub like this one but to run 2 ohms.
Awesome amp for the price being a class D amp designed speciffacly to run a sub.

Really like this sub

Written By AGlow, Macomb, IL on Tuesday, November 23, 2010

I have a 2007 standard cab Chevy Silverado. I have a Kenwood Excelon Head unit, 3-
way Infinity Kappas 6 1/2s in the doors and Kappa 4 x 6 plates in the rear pillars. I was
using my 5 channel infinity kappa amp to run the speakers and then I ordered the sub
and s/o enclosure combo package (12") for some bass. I had to order the shallow sub
because it's all that will fit behind the seat. I was satisfied with the bass I was getting
and the fit of the S/O box. I've since put one of my kappa class D 1000watt sub amps on
the single 12 and I agree that it can be overdriven, easily. I need more bass and am
satisfied with the KFC-WS12. I'm going to order another one. I should get the bass I'm
looking for out of a pair of 12's in my standard cab. I don't believe they will be
overpowered by the amp. I love the sub and believe its doing everything I thought it
could. I've got a pair of 18" Kicker Comp VR in my car so the single 12" is definately a
different kind of bass, but still good.

Decent Sub

Written By FowlerJE, Eastman,WI on Sunday, September 26, 2010

Crutchfield Customer Review (What's this?)

For the price, it's a good sub. However, it doesn't hit as low as I would like.
It says it handles 1400 W, I'm running about 1000 W and it doesn't seem to
handle it as well as it should at very high volumes.

Definetely Awesome for the size

Written By Wayne, Boston, MA on Monday, September 13, 2010

Crutchfield Customer Review (What's this?)

Great sounding package. Running a Sound Ordinance 1500 Mono amp to power this
and it sounds awesome. The remote bass adjuster is a must. Every song is
different and every song needs different level of bass. This package handles it
perfectly!!

A lot of ''bang'' for small spaces!

Written By aleIANated, New Orleans, La. on Friday, June 26, 2009

I have a '99 Ford Ranger with a regular cab. I shopped around for a while looking to put some bass in my truck. I figured I would not be able to put much in there until I found this sub. I didn't even know they had shallow mount subs and when I bought this one and installed it I was trulely impressed. The box was just small enough to fit behind my seat without pushing me up into the stearing wheel or takeing away my leg space. I had bought the Kenwood KAC-7204 amp to push the sub and now it's hard to realy crank it and sit in my truck! If you have a small space to work with and a tight budget, like me, I recomend trying these subs out.
