Kenwood's KSC-SW11 powered subwoofer might look small, but it delivers impressive bass. This little powerhouse will fit under a seat in most vehicles, where it'll produce low-frequency response equal to that of a larger subwoofer in your trunk. It offers a great solution for those who want to reinforce the bass in their system without taking up a lot of space.
This tiny powered subwoofer can fit in many tight spaces.
Kenwood gives you the biggest bang possible by stuffing an 8-1/4" x 5-1/8" woofer into this enclosure. The rigid aluminum enclosure eliminates rattles, while the durable built-in amplifier feeds the speaker 75 watts RMS. Kenwood throws in a wired remote, so you can control the bass from the driver's seat. A wiring harness and mounting brackets are also included.
Easy to install. Sounds great!

Easy to install. Sounds great!
I wanted a very small powered subwoofer to fit on the floor between the front seats in my 2008 Honda CRV LX and this fits perfectly. No passenger or cargo space was wasted. It is fine for my needs but probably not the subwoofer for someone who really wants big and loud bass sound. But if you just want enough bass to enjoy your own music in your own car and don't need to share with all the other cars around, this subwoofer will be fine for you. Installation wasn't exactly easy since there are no step by step instructions available from Crutchfield for subwoofer installation in my specific vehicle but the generic tutorial on the website is very helpful. Plus, I found some videos and blogs online made by people with my model of car who have installed subwoofers and these also helped.
Pros: Small enough to fit in nearly all vehicles and not use up valuable cargo or passenger space.
Cons: Probably not loud enough for someone who wants a very high performance sound system.
Just to set expectations, if you're looking for an obnoxious sub that shakes all the bolts loose from your car, this ain't it. For context, I mainly listen to metal/rock and some psychedelic stuff here and there, so I absolutely was not looking for my system to be heavy on bass....just something to fill out my sound a little more and add some extra depth to it. I previously had a Sound Ordnance B-8PTD in my old Toyota Matrix - a bigger sub with about double the wattage, and this thing blows it away completely. There's a bigger, wider sound with much more control over the frequency, and the unit itself is about half the size of the SO box. I put this one in a 2016 Mustang and it fits right underneath the passenger seat, barely noticeable unless you scoot the seat all the way forward. The reason I'm not rating it a 5 is perhaps more related to my installation than the sub itself...I honestly can't tell who's at fault but there's a gremlin in there somewhere. Occasionally it'll catch a frequency in the music and decide to throw all of its power behind it, going completely nuts for about a second. I can control just how crazily it responds to this anomaly by turning the frequency knob all the way down, but IMO that's not something an end user should have to worry about controlling.
Pros: great sound given its size and price range - also gives you a lot of control over the frequency, not just volume/gain.
Cons: sound gremlin that I can't quite place. Distorts a little at high volumes but that's why you get the control knobs. It's more sensitive to some tracks than others depending on who mixed them.
Nice sound, easy to install, everything included to mount and wire. Great sound. For the dollar. .
Pros: Small all included, wired remote, easy to setup and tune. ??
Cons: None for the dollar
I got this thing in hopes that it would fill in the missing bass that my horrible factory speakers dont give. It doesnt really do that. It makes more noise, but not really good bass. Over all I kind of hate this thing. It would be a different story if it produced a clean sound, but it doesnt. Like I said it just makes more noise... Not good bass, not even compared to the factory door speakers.
Cons: Poor bass/sound
I have had this unit for the past year installed in a 2000 Honda Civic EX Coupe. Sound is amazing. I installed it under the passenger seat and Velcro the control module beside my automatic shifter. Everything is within reach. This subwoofer is connected to my Jensen VX-7200 GPS Receiver and sound is pumped through Kicker Component speakers in front and Kicker 2-way speakers in back. I primarily bought it for just a touch of bass. Not the bone jarring heart attack thumping.
Pros: Kenwood at its best
It's important to understand that this unit has limitations. That being said, for my application (92' F-150 standard cab) this was the perfect choice. The unit fits under the bench seat on driver's side almost perfectly. It completely fills in the deeper sound that the other speakers can't produce. The difference between having it off and on is substantial. You can't buy this unit thinking that it will produce sound at the same level of a 12" amplified sub. It won't. There is no way that a unit of this size can achieve those low hip hop notes that blow doors off hinges. You also can't crank it up all the way and expect it to not distort at full volume. This unit is designed for tight spaces and small cabins, specifically single cab trucks and very small cars. You may have a chance placing it under the driver's seat of an SUV or larger truck, but don't waste your time if you plan to place it in the back or trunk. When blended with the music, it performs flawlessly and is impressive for its size. The construction is solid and installation is very easy. RCA jacks ARE required to connect this unit directly to an after market radio.
sounds pretty good for the size
Cons: would like more power
This is a pretty impressive and inexpensive little sub set up and is very easy to install and integrate into your stereo system in order to give some more power to your lows
Pros: easy to install, inexpensive, good sound
Cons: none at this time
Well just thought I would share. I have the predecessor to this which I bought from here back in 05 and has worked flawlessly. Will agree it's not competition worthy, but does put a good boost. It's been under driver seat in my 03 PT turbo for over 120000 miles.
Pros: Small and kick butt
I installed the it in a 2015 Sonata. The car already had the Infiniti stereo which includes a sub in the rear parcel shelf but bass sounded weak. The KSC-SW11 filled the gap. It fit under the passenger seat although it was a tight squeeze because of the power seat components. I never use the remote control so I left it under the seat beside the sub woofer. I connected to battery, ACC power and speaker outputs at the Infiniti amp in the trunk behind the right panel. The installation is completely stealth: nothing visible.
Pros: Convenience: small size, integrated amp, easy connections
Cons: A wireless control would be better
it took me read a lot of reviews before i decided to get this one. You will never go wrong. I have an alpine 143bt and the additional speaker amp and i add this sub it makes a lot of difference.
Pros: small with big sound
Small compact speaker with lots of power and range. Fits nicely under the rear seats. Great price and great buy.
Pros: Can be hooked directly to one speaker, then has an amp for added power.
Cons: If you don't buy it you'll regret it.
Great product. Found cheaper elsewhere! Am returning to Crutchfield. Customer service explanation was that they are an official Kenwood seller.
Have purchased from crutchfield for many vehicles. This is the first time taking advice from a sales advisor. All I can say is "HOME RUN" with the products I needed, as well as didn't need.
Pros: Extremely easy install. Sounds great. I'm not breaking glass with it. But compared to the stock system in my 2015 jeep wrangler unlimited sport. It is perfect, Completely hidden under the passenger seat.
Cons: None so far...
I ordered this sub to add low frequencies to my stereo. Honestly, it is louder than I expected. Although, it will not disturb the car next to you at a red light. I mounted it in the drivers side rear compartment of my double cab Tacoma. The install was very simple, only taking me one hour. (I do have a background in auto mechanics, so this probably helped the install time.) I you are looking for a nice sounding, very compact sub, then this may very well be worth considering. I know I do not regret purchasing it. Do keep in mind that this sub will not rattle your vehicle, but it will really add the low frequency definition that car stereos lack with just door speakers.
Pros: Easy install. Very compact.
Cons: None as far as I am concerned.
Maybe I was expecting to much. I have a f150 with a good after market head unit and speakers and was hoping to feel a little bump but honestly I hear very little difference with it off or on.
Pros: size and ease of hook up
Cons: not much there as far as sound
Sound quality is very good and the unit pairs well with the rest of my system. I installed this behind / under the passenger seat in my 2015 Jeep Wrangler "Willys". It will not fit completely under the seat so I had to build a brace / extended leg to support the corner that hung out over the dip in the passenger floor. It was an easy mod and worked like a charm. All in all, I am pleased with the unit.
Pros: Good solid lows for a very compact unit. The wired remote is a nice attribute as it allows you to control the bass easily throughout different styles of music.
Cons: I wish it were slightly thinner so it would completely fit under the seat.
With some finesse, I installed this compact subwoofer under the passenger seat of a 1995 Chevrolet Camaro Z/28 convertible. It was not ideal to fill limited trunk space with audio equipment. As expected, the product provides ample low frequency response to balance sound. Bass is adequate, though not overpowering, and sufficient to fill the cabin area even with the top down at highway speeds.
Pros: Better than the subwoofer that is too cumbersome for your application. Fits where other products do not to get the job done (if your goal is not to shake the car next to you). Easy to install/wire. Adjustable.
Cons: Some distortion, if not carefully tuned. Not particularly powerful or refined.
I just baught a used 1996 Mazada Miata from my mechanic. Amoung other things the radio had passed away and I had to replace it. I got a Kenwood DPX791BH and was looking for a sub to round out the sound. I settled on this. This car has very little room to start with and so I needed the smallest unit I could find. I also wanted to keep it simple buying the same brand that the radio was. Okay so I had my mechanic install everything and then I drove it home. It sounded like crap. The sub was bonky sounding and the highs were ear pearsing. So I had a little tuning to do. I This head unit had a 5 band equalizer in it to tune up the sound as well as a full set of sub controls built in. First I kicked the sub down to 85 hz and then took loudness up to +1. Then I went to the 5 band EQ and took out the door speakers by tuning them down in level one and two to -5 the other three settings (bands) I left at 0 neutral. Now the sub was starting to do it thing. I could tune the base with the sub control and fill in for the lack of base out of the door speakers. Now the unit is starting to perform. As a mater of fact it sounds really good. I did have to fiddle a bit but I'm there now. I placed the unit behind the drivers seat, (it won't go under the seat) as an other fellow stated you have to be 5'-10" which I am and it allowed me enough room under the wheel to stretch out my legs. Now the little thing pumps out some pretty impressive lows and really the car sounds great. Get one.
Pros: Lots of bang for the size.
Cons: Your going to have to mess with your sound settings to get the best out of the thing.
This is a subwoofer is perfect for someone that wants to add some more bass to their system. After first seeing the wiring, I was kind of turned away from installing it myself, and but once I took a look at the diagrams supplied, I realized that it would not be too difficult, and had it done in just a few hours.
Pros: Small. Durable. Easy to install.
I put this in a 08 F-150 super crew cab under the back seat. I also installed new Kenwood 6x8's all the way round with a DNX692 Head unit. this lil set up does not give much more bass then the 6x8's. I have tried all kinds of setting trying to tune it in. If you only listen to older rock or country, this will give it just the lil edge that makes you smile. anything more present... not worth the money. I have an old 6-1/2 Bazooka bass canon with a 50wat power supply that will leave this thing sitting in the dust. not sure if i will return it yet, It does not take up much space at all, which is what i need with a family of 6 in a truck on camping trips.
Pros: easy to install Looks nice under the seat compact, can fit most anywhere
Cons: does not produce the bass I thought it would will distort at higher volumes. as the radio goes up, need to turn the controller down
Great sounding sub, really great wiring supplied that made installation as easy as it could be.
I have never tried a compact sub till now. Put this under the seat of my 01 PT Cruiser and it fills the music all the way down. It is hooked to a Kenwood KDC-X399 eXcelon purchased from Crutchfield. I only need 1/4 volume on the remote to get the perfect bass accompaniment I want. Will probably add one to the wife's van as well to enhance her stock radio.
Pros: compact and fits under the seat no problem. Comes with needed wire to hook it up and hardware to mount it. Sound is amazing for its size.
Cons: Only one I can think of is it does not come with RCA cables to connect to the sub output of an aftermarket radio. Really wasn't a con for me because I already had some laying around. Might be to tothers.
Got this on recommendation of a friend. Did NOT think this little thing would do much as far as adding low end pinch to my car........BOY WAS I WRONG!!!!!! Not going to shake your neighbors walls or annoy other drivers...but inside the car is INCREDIBLE!! I have installed a complete Kenwood system , media player, 6.5 3 wa's in doors and 6x9 in rear deck. Sounded good...but just need that extra OMPH TO REALLY create the nice clean sound a I was looking for. THIS LITTLE SUBWOOFER DOES THE TRICK.......AND THEN SOME!!!! Installed this under my passenger seat. Made a IMMEDIATE DIFFERENCE!!!
Pros: Nice clean bass for ADULT LISTENING NEEDS. Makes R&B, POP, and current top 40 music listening GREAT!!!
Cons: Not the right choice if you are looking for door shaking boomy bass!!
This product I have purchased is exactly what I was looking for,sounds great in my car without it being too loud on the outside..
Pros: Fits great under my seat,sound quality is awesome with adjustable volume on the bass right at your fingertips without having to use the receiver...
I'm shocked. I have a 98 Jeep Wrangler TJ and my objective was to add some volume (road noise is tough to overcome in the Wranglers) and a little punch while hiding the equipment. I got a Sound Ordnance head unit, 400w RF 4 ch. amp, Polk 5 1/4" sound bar speakers and fronts, and the Kenwood powered sub. I am absolutely thrilled with all of it. The Kenwood fills in the low end perfectly. It fit under my seat, and is completely out of sight. I was very skeptical about the size and shape, but it sounds so good. It gives a great punch without overwhelming the mids and highs. It's a great product that I would recommend to anyone who is over the boom car stage, but still appreciated great sound. I also have to mention I got it in five days, including a weekend. Thanks Crutchfield!
Pros: Easy to install Sounds amazing Customizable sound with remote Easily hidden under seat No distortion at higher volumes Crisp powerful punch for small unit
If space is a premium requirement, look no further and consider the Kenwood KSC-SW111 to fill your bass sounding needs. Installed this on my 2015 Honda Fit LX and located it underneath the front passenger's seat. Am using the OEM HU going through an Audison Bit Ten D sound processor. The Audison has one dedicated sub output which has to match with the Kenwood's dual inputs. I used a 2 to 1 RCA plug converter. Other components are a Kenwood Excelon 400/4 amp connected to Polk DB6501 speakers. My system is not the loudest but is audiophile quality and light years clearer than the OEM system. The bass produced exceeded my expectations for a component having a very small footprint. Its clear, tight and can be thumpy with zero distortion!!! Don't let its rectangular speaker design give doubts. It works exceedingly well. I now, often drive the wife anywhere and wait in the Honda listening to music. That's how good the sounds are. This little Kenwood sub continues to produce tight, solid bass. Perfect to fill a sub-compact like a Honda Fit without taking up any valuable space!!!! Have been using this for the past 8 months and it just sounds sooo good!!!!
Pros: - firm, solid bass notes - controllable with remote - compact size - quality enclosure - complete wiring with sufficient length
Cons: - not the cheapest but certainly my choice for a powered sub with the smallest footprint.
Great little sub for my Blazer. Installation was a breeze for the sub and the sound quality is great. I was not looking for the window rattling of bigger units just something to fill the sound stage. Would recommend to anyone that wants a small sub that fit just about anywhere.
Pros: for me it was all pros
Installed in my 2004 Scion Xa. Fit perfectly under passenger seat. Took seat out of car to be able to cleanly run the wires and was able to come out from under the carpeting next to the heating/cooling duct under seat. Secured it down with velcro and ran remote control to my glove box. Have it hooked up to the rca sub out of my Pioneer DEH-X9600BHS, set the remote on the Kenwood powered sub to 80hz and volume half way as a starting point and adjusted subwoofer out settings on my head unit. All I can say at this point is WOW! fills in the low end nicely. I was not looking to rattle my rearview mirrors just looking to fill in the lacking bass from my 6.5" door speakers and this works fantastic!
Pros: small, compact, powerful, easy to adjust settings on included remote
Cons: none really
Great little subwoofer with outstanding output and tune-ability. Really brought my stereo alive in my single cab pickup.
Pros: Relatively compact, good bass output and may fit under some seats. Works extremely well with my Pioneer X2600BT head unit.
Cons: Was a tad taller than I anticipated requiring me to put it in a new location.
Installed this in my 2014 Chevy Traverse on Saturday. Since the floor heat ducts are under the seats and there was no room to mount it there it was a challenge to find a spot that It would not interfere with cargo space or passenger entry exit.. I found a great spot after a little digging and it sounds great and is complete hidden with no interior modifications. The install instructions were simple. The most difficult part of the install was locating an ignition only power lead for the blue wire.
Pros: Great sound, fairly simple install.
Cons: None so far.
This little powered sub fits perfectly under a seat in my 2009 Ford Ranger. It took longer than I thought to install, but I did remove the drivers seat for more room wiring into the rear speakers and pulling trim for a professional look. Also after 2-3 hours the no see-ums mounted a massive attack on my legs, so I did this over a 2 day period. I couldn't find a fuse or relay for the power with ignition in the on position, so it's straight wired to the battery It sounds amazing in the small cab. Wife got me the new AC/DC, Nickleback, and Little Big Town cd's for Christmas and they all sound great. My daughter had to put in one of her hip-hop cd's, and I gotta admit even it didn't sound as awful as normal. This little sub is worth the money and time to install.
Pros: Sounds great. Always go with a top name brand
Christmas present for my husband he loves it
Pros: Made my husband happy
My head unit is a Naka-NA780. I recommend using a low level out. From experience I can say that the hi-outs don't offer the same level of control or low hz sensitivity. Heck using high level outs is akin to using buckshot when a .22 will not only be more cost effective but more efficient and efficiency is what we're talking about here folks. This powered sub provides an abundance of usable bass across a wide range of frequency. Granted it won't slap like 400ws pushing 10" subs but what it provides is adequate. Listening to hip hop brings a grin to my face. It can handle it. Classic rock works well too. Rory Gallagher has beats!!!!!? Proper installation is vital. As with anything execution is key. Conceivably you can rig up a plug and connect it to a cigarette lighter. I urge you to ditch the supplied 14ga 12vdc power cable and use copper 10ga routed to the battery. Mount it to the floor or someplace secure. This amp is worth the trouble. A quality component that should last you for years.
Pros: Compact size Base response Remote Control Length of cables is excellent. You could mount it in the trunk
Cons: Supplied power cable is horrible. Use some decent copper and run it to the battery.
For NC Miatas (at least NC1s) , this won't fit under the seats but will fit on the panel behind the seat if you can afford to give up a small amount of seat travel. I'm 5'10" so this fits with no sacrifice for me. I bought this to fill out the factory Bose amp and speakers running off an AVIC-8000NEX head unit and it has exceeded my expectations. It's as close to ideal for this car as you can get as long as you can give up an inch or two of seat travel. Installation was straightforward. I'm running off the RCAs from the Pioneer and you don't even really need the remote if the head unit has good sub controls. No rattles. Plenty powerful enough to be effective top down at highway speed.
Pros: Easy installation, good sound, good value.
Cons: None that are apparent assuming the long term performance holds up.
Love this little sub, compact and easy to work with. Plenty of sound for a convertible with the top down as well as top up.
Pros: Compact, great low end, easy to install, on the fly adjustemnt.
Cons: Bolt down screws long quite long enough to reach through carpet and basemat.
i installed this unit in my mazda Miata. plenty of lower end in such a small cabin. managed to get it under the passenger seat.
Pros: lots of sound for the price. easy to install.
This was exactly what I was looking for. Big sound in a small package. Very happy with this item.
Pros: Compact, Sounds Great
Cons: Maybe different mounting options
This little powered sub packs a lot of bass into a small package. I was not looking to rattle the windows, but you can definitely feel the music if you crank this up. It makes for a much more enjoyable listening experience for a variety of music styles at any volume level. This was easy to install, about at the same difficulty level as putting in a new head unit. The great thing about this compared with other powered subs is its smaller size without sacrificing sound quality, and the ability to attach the power line to your internal fuse box rather than going through the firewall to connect directly to the battery. I originally intended this to go underneath the drivers seat in my 1997 Honda CR-V but it did not quite fit there - the wire on the seat adjustment lever sits too low to fit this underneath. So, I installed it on the floor in between the two front seats and just in front of the center dash console. Kind of unusual to put a sub in that spot where it's visible in the front of the vehicle, but it sounds great to me and that was the best spot for it in a CR-V. I definitely recommend this subwoofer - you won't go wrong if you're looking to punch up the bass in a compact, affordable package.
Pros: Straightforward installation, you can attach power line to internal fuse box rather than going through firewall to battery, great bass response for a small package.
Cons: Did not fit under my seat in 1997 Honda CR-V - wire for seat adjustment sits too low.
Easy to install, sounded great till it died. Just bought another one from a different vendor, as it was cheaper. No complaints about Crutchfield... They did a good job of getting it to me.
I installed this in a subaru legacy after adding component speakers, a 50x4 watt rms amp, and door dampeners. Most other under seats were too large. I expected the small size to offer little bass, but it offers plenty. It won't shake your whole ride, but it's more than enough bump for rock/metal/country/classical/etc. with the gain at 50%. The build is sturdy metal, and it comes with enough cable to mount the unit in a trunk or SUV bed. Fuse is included. Power is supplied from your fuse box, rather than batter directly.
Pros: Sturdy, lows are clean and loud. Remote control is nice. Mounted it next to my seat. I do a lot of on the fly adjustments. I'd probably go crazy without it.
Cons: This "fills out" sound. If you want huge bass for hiphop/bounce/etc, this will flub out on you. I tried pushing it in that direction for fun. Won't be trying it again.
The sub is a good deal for the price and for what it is. But personally I didnt think it was enough bass so I bought another one to put under the passenger seat. So with the two of them it sounds decent. I did not want a box in my trunk area of my SUV taking up any space, so this was my best option.
Pros: Can fit under my seats, not too expensive, sounds decent for how small it is
Probably did need this sub but I'm glad I found it and purchased it. Compact, clean install, and really tight bass and sound pressure level.
Pros: Small and clean and powerful
Cons: cant think of any cons
This is very close to the smallest i have found for my Ranger single cab, This thing puts out more bass than i need in the small cab, it was also super easy to install, took about 3 hours to install it (pulled carpet and seat to get the clean "factory" install look,) very happy with the outcome. I dont know if i would put it in a trunk but would use one in a larger truck no problem.
Pros: Super Small, insalled easy, and puts down plenty of bass in small space
Cons: Not enough bass for every vehicle or air space but beyond enough for small areas
Easy to install. Its my first sub and its a very nice compliment to my system. It wont break windows but the sound is great.
Pros: easy to install, great sound.
Cons: Dont expect it to annoy people at stoplights.
I am using this in a 2000 Porsche 911 Cabriolet. Bought specifically for the small size - I have paired it with a Kenwood DDX370 DVD head unit and I am using the stock speakers. It sounds great. The remote allows me to adjust the base easily depending on if the top is up or down.
Pros: Compact size - good sound in a small interior.
I had installed a new Sony Mex-3100p and some speakers in a 2011 Rav4. It sounded pretty muddy. I then added the Kenwood KSC-SW11 and removed the low frequency sounds from the door speakers and now the stereo sounds fantastic.
Pros: Small- fits under back seat. Great sound.
Cons: Needed to buy additional 16 gauge and 12 gauge wire to reach the sub under the back seat. Need to buy separate RCA cables (I my case 16 feet long)
Fresh install, so ask me in a year. However, I had a challenge - get some bass into a very small, high-performance Italian super-car with little space for such things. I might have used the Sound Ordnance box, but it was too wide. This Kenwood fit the bill for size, so it was in. Hooked up with provided parts and cables. Lit up and filled up the car on the first try. I'm not expecting, nor did I want, a big thumper. This car will be playing a wide range of music favored by those of us that grew up on the 60's and 70's, and this unit has made that possible.
Pros: Small size, very well constructed, optional input choices, complete kit, remote control includes volume, cutoff, and reverse polarity switch
Cons: The remote control has the cable entering from the bottom. For my application I brought the control into a tiny glove box, meaning that the control is upside down to the operator. No biggie, as it's bog simple, and once set is unlikely to be fiddled with.
bought the kdc sw11 powered amp and the kdc x997 head unit both by Kenwwood and am very pleased with both. The clairity is amazing and this is with the stock speakers.going to change to new speakers and will then decide if i need en external amp
Wonderful and compact self-powered sub is just what you need to add that bass to your music. This amp is fantastic unless you are a hip-hop fan and want it to overpower the music completely. Provides great low end to all forms of music.
Very impressed with the bass out of this because when I took it out of the box I realized just how small this thing is. I was thinking I was barley going to hear it but I was shocked. Don't get me wrong, I had to turn it up all the way to get good bass but I was impressed. The car was a hatchback and we just set it in the back.
Pros: Great bass.
Cons: A little more power would be nice.
I have been very satisfied with the sound quality and its small size is a big plus. You will need some bullet connectors to tie into the power on wire. You will also need the bullet connectors and some way to connect to your battery. I was able to fine everything I needed at autozone. It does not come with RCA wires but it will tie into your speaker wires if you go that way. All in all a great way to finish off your aftermarket set up or your sub par factory set up.
Pros: Small size, great sound, easy hook up to the sub, and remote for easy adjusting
Cons: Will need to get some hardware and RCA cables.

I wanted a small powered subwoofer that will not take up usable passenger or cargo space in my 2008 Honda CRV LX. This should fit perfectly on the floor between the front seats and below the folding console. ( If not, it should fit under the driver's or front passenger's seat.) [ John W. Oct 15, 2016 ]

Very good for size. Easy to install. Considering getting another in the future, so there's 1 under each seat for extra oomph [ Nicholas Apr 15, 2016 ]
Formfactor and the rest of my system is Kenwood. [ SCOTT Feb 03, 2016 ]
Will fit under seat of 2014 Chrysler Town & Country [ Robert Dec 07, 2015 ]
no adjustments on unit for someone seated in back to kick when under seat mounted. [ weldr1 May 07, 2016 ]
Hello. The two jacks are for an included wiring harness (your power and signal inputs) and the included remote control (looks like old style phone jack.) I have been happy with my unit. Very easy to move from car to car. [ michael Aug 29, 2016 ]
This is for all of the available compact subs, I would recommend to contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle, compare the different subs available and give you the details on if they will fit and what you will need for an installation in your vehicle. [ Kenny Jun 03, 2016 ] Staff
18-16 gauge on the remote turn-on lead and 12-14 on the power lead (as best we can tell as they do not provide the gauge specs in the manual.) You can also contact Kenwood directly for the definitive answer: 800-KENWOOD. I hope that helps! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=5 [ Ryan May 24, 2016 ] Staff

Absolutely. A moderately powered subwoofer will be fine. High powered multi-amp systems are definitely not recommended but the power draw from this single subwoofer will not be a problem. I hope that helps! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=5 [ Ryan Jan 25, 2016 ] Staff
A rep at Crutchfield helped me hook the power to the sub using blade fuse adapters to the windshield wiper fuse. As soon as you start your car, or the key is in the on position, power is applied to the sub, and like wise removed when you turn the key off. This worked for my 2009 Ford Ranger but your car maybe wired differently, so be sure to ask for an installation tech (?). They're very friendly and knowledgeable. Hope this helps. [ Mike Dec 16, 2015 ]
Yes, just connect the blue wire. [ michael Dec 15, 2015 ]
Yes, it does. [ Larry Dec 14, 2015 ]
I didn't install this myself but, after install the amp knew to turn itself on and off when the car was turned on and off. I'm assuming that's the responsability of one of the wires that comes with a standard wiring harness. Not sure about technical side of how to make that happen, but the answer is yes...the amp will do that if installed correctly. [ Tristan Dec 14, 2015 ]
I think it would work for you. It puts out a surprising amount of audible bass. I have it in a 2014 Spark EV and it will vibrate the rearview mirror. It makes the paltry 4" speakers in the car bearable. That said, the driver is small so don't expect it to thump like a 1000 watt 12" subwoffer in a large bandpass box. It will add some noticeable bass to your 6.5" speakers. [ Charles Nov 21, 2015 ]
Tyler, Great question. I've bought two of these units, for different vehicles, so here's what I can tell you: I put the first one in my 2002 Ford Excursion. It noticeably increased and improved the bass. I too was not looking for a "thumper," but definitely an improvement over not having it. However, with a vehicle that big, I decided two of them would work better. Both were placed under the center seat. I was very pleased with the sound I got. Primarily listen to classic rock, some country and also some gospel/religious music. The latter being mostly live recordings. For all of the above, the sound was dramatically better than stock, but I replaced the head unit and all the stock pieces as well. I ended up selling that one in a moment of weakness and really miss my big SUV. I also have a 2003 Corvette coupe. I replaced the factory setup in it just recently. I used one of these subs mounted along the back wall of the luggage area. In a vehicle that size, one unit seems to be plenty enough. Again, I want to hear, and to a slight degree, feel the bass. But I did not want the thumping or vibration commonly heard amongst people half my age (or less). Overall, I'm very pleased with the product and found installation to be easy. Hope this helps! [ PAUL D Nov 20, 2015 ]
Hey Tyler - I have a 2016 Santa Fe with a subwoofer under each front seat. This Kenwood is the best choice if you have limited space and need to fill that low end void. This particular unit is a bit on the "punchy" side, meaning it hits the mid-bass very well but struggles to find the very bottom of the frequency spectrum. That's a small gripe - this little guy definitely makes the music much more enjoyable and it's got a very handy remote control that should let you tune it to fit your taste. Good luck and enjoy! [ William Nov 19, 2015 ]
I run a similar setup in a convertible with this powered subwoofer due to space constraints. It is mounted under the passenger seat. Even with the top down, I have found this unit provides ample bass to fill out lower frequencies that most amplified 6.5" speakers lack. It is fair to describe the sound quality as balanced, but there are certainly more expensive units that perform better. Overall, it is excellent value for tight applications or cabin fill. [ ROBERT Nov 19, 2015 ]
No, not with this one. I installed this amp/sub in my 2014 Ford Focus and no battery modification was needed. I forget the wattage of the amp, but relative to many amps it was quite small. This amp/sub combo is one of the best compact, and low-power amp/subs available. The bass it puts out is tight and punchy...very little boom or rumble...yet you disn't ask about it so I won't ramble on about all that. [ Tristan Aug 08, 2015 ]
Personally, I've never heard or seen of a recommendation to increase battery capacity for any aftermarket components. Batteries are used to start the vehicle. Once it is running, power comes from the alternator. The only problem with the battery is if the alternator goes bad, subsequently not providing enough charge to power all accessories, run the vehicle and recharge the battery, you will eventually exhaust the battery. Having said that, I have one of these in a Ford Excursion diesel. You'd never see the impact on that vehicle in terms of electricity. I put the newest one in my Corvette, no problems. I have different components but with the same power draw installed in my HD Ultra Classic, no problems. So, if a motorcycle can handle the power requirements of these pieces, I cannot see why any car would have a problem with this unit. Remember, this sub will enhance bass output and definitely improve the sound of music in your vehicle. However, this isn't going to produce the obnoxious thundering booms so many kids do these days. But it will definitely enhance my classic rock music collection and really wakes up "Dazed and Confused." [ PAUL D Aug 07, 2015 ]
Not required! [ Larry Aug 07, 2015 ]
I had to buy my own RCA cables [ VIREN Jul 14, 2015 ]
rca?it comes with alot of different wires [ Rollin Jul 14, 2015 ]
The 10-pin connector cord (5m/16ft) has power and speaker input. RCA cable can be connected to 10-pin connector. A RCA cable is not included. [ KEITH B Jul 14, 2015 ]
Yes [ Ronda Jul 14, 2015 ]
the unit has female rca connectors.. [ WILEY JAMES Jul 14, 2015 ]
I didn't screw down just put coarse side of velcro on bottom of sub [ Rollin Jun 04, 2015 ]
Yes I would secure it. I installed this in a jeep wrangler and I actually used adhesive velcro strips as I wanted to be able to remove or move the subwoofer as there is very little trunk space. The Velcro works greats and gives me good flexibility when I need to use the trunk. The unit comes with brackets and can also be secured with screws but the velcro I used certainly is strong enough to retain the unit. Hope this helps. [ Paul Jun 04, 2015 ]
My husband put mine in the trunk, up against the rear seat without any method of securing it. I have a Cadillac CTS and haven't had any issues with the subwoofer sliding, or shifting. [ MARCI K Jun 04, 2015 ]
Hi Rob, Yes, securing the subwoofer would be advisable. Mounting hardware is included and it is easy to do. [ ALFRED Jun 04, 2015 ]
Yes, definitely. It's a potential safety hazard if a subwoofer is not secured to the vehicle. You will need to screw the unit into the carpet either under your seat or in another location of your choosing. The Kenwood KSC-SW11 comes with the screws. [ David Jun 04, 2015 ]
Velcro tape strips worked great [ VIREN Jun 04, 2015 ]
You want to secure it as well as possible for both sliding and more importantly, sound. Subwoofers that are not mounted properly will disperse the sound waves into distortion which gives you no chance at good bass. This little guy, when mounted properly under the seat, gives a nice punch when it's tuned correctly. It's not going to get to the very low notes - need a larger enclosure for that. But it certainly fills the gaping hole in bass that the factory speakers simply can't fill. I would recommend this product to anyone who has a tight space to work with and it's a good value for the price. FYI - I'm a former national "crank it up" champion so this advise isn't coming from just any random customer. Good luck! [ William Jun 04, 2015 ]
In a 2006 Camry XLE, there was no need to secure the subwoofer because it was such a tight fit that I had to remove the seat, set the subwoofer in place, then bolt the seat back over the subwoofer with the steel crossmembers of the seat pressing against the subwoofer housing. There is almost no way for it to slide around under there. All that said, if the seat was not physically pressing against the subwoofer, I would have secured it with straps because I think it is light enough and the bottom is not rough or "grippy" enough to stay in place under heavy acceleration/cornering/braking without sliding around under the seat. Not asked, but opinion offered here: great sound, especially for the price. We are very happy with our purchase. [ AUTUMN Jun 04, 2015 ]
Really depends on the application. I have mine located under the front passenger seat - there is no rear seat to speak of so the unit does not slide around and I do not have it fastened down. If you have lots of room under a seat or are placing it in the rear cargo area of a SUV, etc. you probably will want to fasten it. See page six of the owners manual - you can find it on the Crutchfield website in the "details" section. [ JOHN Jun 04, 2015 ]
It has two slotted brackets that hold it to the floorboard of your vehicle. Normally there is sufficient room underneath the seat and I highly recommended putting it under the driver seat. [ STEVEN Jun 04, 2015 ]

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your gear. They will be able to pull up the Boss 470 and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Jeff Mar 06, 2015 ] Staff
According to page 7 in the Kenwood instruction manual the KSC-SW11 will work without the remote connected. Text from page 7: "The sound is output even when the remote control unit is not connected, but the operations described in this section are not available. In this case, the volume, cut-off frequency and phase are set to the predetermined default conditions, with which the cut-off frequency is 125 Hz and the phase is 0º (positive)." [ (unknown) Feb 05, 2015 ]
I just set the unit controls to a mid range, and then use the head unit controls to adjust. I think that you need the unit controls set at something, and the head only adjusts from zero to that setting. I like it, it is in the cab of a diesel puller motor home, and it makes all the difference. [ scott Jan 26, 2015 ]
I would think what you are suggesting would work but one thing to consider, it is much easier to fine tune your subwoofer from the hand held remote that going into the features on the deck. I did the same thing on my home audio system. I turned off my subwoofer controls on my receiver and did all my fine turning on the subwoofer itself. Using the hand held remote lets you dial in the cross over and volume very easily while listening to the music to optimize your sound and lets you make small corrections as needed to make it perfect. I wired mine to the center console in my truck. Out of the way but always in hands reach when I need it. Dean [ DEAN C Jan 25, 2015 ]
I use the remote as it provides quick and easy adjustments, use two sided tape to mount it [ STEPHEN M Jan 25, 2015 ]
Obviously different head units have different controls. Mine is mated to a Kenwood head unit with both tone controls and an equalizer. However, there are additional adjustments to the subwoofer that only the remote allows you to do. Specifically, you can adjust the volume to get the desired level of bass without resetting your head unit. In my case 95% of what I listen to are CDs copied to a USB drive. Sound levels vary from disc to disc, as do bass levels. Having the remote at my fingertips enables me to adjust as desired. Another benefit of having the remote visible is this: my head unit has one in line fuse. However, it became necessary to add extra in-line fuses, acting as a relay, between the subwoofer, amplifier and head unit. When one of those relays (fuses) blows, the remote control for the sub doesn't light up. That makes diagnosis easy, as well as the fix. In my case, I found that there is sufficient fluctuation in my truck's power output to warrant adding those fused relays. Better safe than sorry. Easy to do and cheap protection. Hopefully this answers your question. I say use the remote and install it in an easily accessible location. Mine is attached to the console on my Excursion, next to the drivers seat. That works great for me. Good luck and enjoy your new stereo! PDR [ PAUL D Jan 24, 2015 ]
You to adjust this setting. Volume affects only the volume of the subwoofer. Frequency adjusts the crossover only, it has nothing to do with volume. There is no "max" for frequency, that only sets the wavelength of notes that come from the sub versus other speakers in the vehicle. [ PAUL D Feb 09, 2014 ]

Sales is really good at setting up what you're buying with your specific car, if your factory stereo supplies a power antenna / amp signal, rca outputs/ or use speaker connections for the input side you should be OK,but again. Crutchfield is the one to ask. I had an aftermarket stereo, so it was the setup for me. [ derek Nov 01, 2016 ]
