Our take on the Kenwood KSC-SW1

Kenwood's KSC-SW1 subwoofer may be just what you need if you're looking for more bass, but don't have space for a conventional sub box or powered sub. This compact sub features an amplifier that pushes 150 watts max to a 6-1/2" woofer, with a 6-1/2" passive radiator built in for good measure. It's all housed in a rugged, low-profile enclosure that will fit just about anywhere.

The passive radiator technology is one of the keys to the surprisingly big sound of the KSC-SW1. Air pressure from the powered woofer moves the unpowered 6-1/2" radiator, augmenting the bass response. Both subs are housed in a non-resonant cabinet with a rigid aluminum die-cast back panel. The rigid cabinet reduces vibrations that distort the output of the speakers, so you'll enjoy clean bass.

Kenwood has included a wiring harness that includes a power and ground cables, speaker input wires, and a fuse. Included mounting brackets help you mount the KSC-SW1 securely. And, the wired remote control lets you adjust the level, phase, and the low-pass filter settings right from the front seat.

Features

Product Overview: The KSC-SW1 amplified subwoofer features a 150-watt (75 watts Peak x 2) amp, a dual voice coil 6-1/2" concave woofer, and a 6-1/2" concave passive radiator, all housed in a rugged, ultra-compact enclosure that will fit just about anywhere. The KSC-SW1 creates impressive bass through passive radiator technology. Air pressure from the powered 6-1/2" woofer moves the 6-1/2" passive radiator, augmenting the bass response.

Wired Remote Control: The wired remote control provides fingertip control over your low frequencies. You can raise and lower the bass level and the crossover point, plus switch the phase from 0° to 180°. The remote control can be attached anywhere using the supplied Velcro strip.

Mounting Options: The subwoofer, with it's 3-11/16" height, can be mounted flat under a seat in the passenger compartment, or in the trunk. With the included brackets, the subwoofer can be mounted on its side in the trunk or in the cargo area of an SUV.

Mounting Notes: The side bracket extends the overall depth to 4-3/8". If the upper screw holes are used, the side bracket raises the overall height to 10". The horizontal mount brackets extend the overall depth to 11-3/8"

Cable Management: Even though the connections are on the bottom, the unit mounts completely flat thanks to a 1-3/4" wide and 3/8" deep groove in the bottom for cable management.

Very Good COmpact Sub

Written By sansone, All over New Jersey on Sunday, September 07, 2008
 
Installed this in my 2008 Xb, under the passenger seat. Fits great and does provide very good sub, but you will be limited due to its size. You wll hear & feel so much better bass than factory system, but it could be a bit more fuller/powerful. (The problem is, I have a VW Jetta w/ Monsoon, and the sub in that is my benchmark and just can not be matched) You will not pound the neighborhood, but inside it sounds nice. Also installed Infinity 3 ways in the front doors, Infinity tweeters in upper rear, and blaupunkt 2 ways in the lower rear doors, so overall my system sounds great, however, I think a slightly larger size sub would probably make it sound just one notch better. But if you want to install an under seat sub, choices are limited, so this is a very good choice for the money/easy install.

Wondering if the Blaupunkt 8" power sub might be a better choice for my vehicle. May have to try it and see...

Kenwood KSC-SW1

Written By Bigsur, Hampton Roads, VA on Tuesday, May 06, 2008
 
This sub is great when considering price and size. For the most part, it sounds great, but it does tend to distort at higher volumes, especially with certain types of music. It's not going to give you the big sound typical of most larger subwoofers, but if all you're looking to do is fill the void when not getting enough bass from your door speakers, it does the job. I'm personally wondering if the KSC-SW10 would sound better; not sure. Overall, great subwoofer.

Good for compact car or truck, enough to fill the bass

Written By mikew151, Alpharetta, GA on Wednesday, January 30, 2008
 
I just purchased this Kenwood KSC-SW1 and here is my rating:
- Good to fill bass on factory setup. This subwoofer, like most people say in the review, good if you dont have space in your car or truck. But don't expect this subwoofer to thump. It will distort if you play hip hops or rocks in high volume.

- I am not a big fan of big 12 inch subwoofer that can rattle my car but at the same time I want to feel bass pounding. I dont get that from this subwoofer.

I owned 8 inch Bazooka, MTX X Thunderlink and this, overall, I like MTX X Thunderlink the best. The reason I got this one is because of its size. If you're like me, like the bass but dont want to wake your neighbor, go get the MTX Thunderlink.

However, if you want just to add bass because your factory setup is lack of it, then get this subwoofer. But if you have 6x9 speakers or component speakers with amp setup, this subwoofer wont make a different that much.

Best small sub

Written By fastfords, Erwin,TN on Tuesday, January 22, 2008
 
The Kenwood sub was a great buy with my Alpine reciever and polk speakers, put it in a ford ranger what a big difference. It sounded like a $5,000 system. For the money you can't beat this system. Easy install and Crutchfield had it at my door in two days what fast shipping. I will buy again from these guys. Thanks Crutchfied

Kenwood KSC-SW1

Written By Louie, Oakland, CA on Monday, December 17, 2007
 
Will not provide shaking bass, BUT definately fills in the lows that my Sony CDX-GT400 lacked. I placed this sub underneath the passenger seat of my Toyota Matrix and it feels great to have the bass right next to you. Easy install toke about an hour, I highly recommend getting lower gauge wires, since the wires that came with it are suprisingly thin. This is a great sub for those who want added bass, but not recommended to those who listen to hip hop, rap, or heavy rock for this might disappoint you (will distort). Also, I love the compactness and space saving design.

Blown away!

Written By rusooo, Ca on Tuesday, December 04, 2007
 
This little guy is being used on a '00 Focus ZX3 with Kenwood HU, Knwd KFC-P707 components, and stock speakers. I really wasn't expecting much from this but 'boy did it wow me. It's very user friendly, even for a novice, and gave me just the right amount of base(although you have to play around a little with the adjustments). If you want a good listening system with a little kick, get it, if you want to blow your door's off, this obviously ain't for you.

2007 Highlander

Written By dus10, Scottsdale, AZ on Tuesday, September 25, 2007
 
Using the factory JBL head unit and speakers (w/o navigation) I placed this unit in the back cargo area facing in towards the rear side panel (using the vertical mounting brackets on a 3/4" piece of particle board.

This Kenwood set works well - in my vehicle it fills the void that the factory speakers can't handle - I've dialed the factory speakers down on the bass and let the subwoofer do that work.

For the money and compact size it's a great unit. It won't rattle the doors and it does have limitations - but for a good fill-in sound with the ability to dial in the cut-off and volume with the remote it surely makes a difference.

I recommend this unit if you are looking for similar performance.

Huge Bass, Small Package

Written By Greg, Muskegon, Michigan on Saturday, September 22, 2007
 
Installed in a 1990 Ford Ranger regular cab with very little room in the cab! I have had several powered subwoofers a lot larger to achieve the sound this unit produces. If you want great sound out of this subwoofer, you must not install the power, ground & audio cables provided with this subwoofer! I did not like the multi pin connector this unit uses for the power, ground & amp turn on lead. I cut that part off at about two inches and soldered on an EFX 8 gauge amp wiring kit # 142PA8 sold here. After breaking in the subwoofer for 24 hours hooked up to a Kenwood head unit # 113KDCX491 also sold here, It was time to let it rip! I listen to Rock-n-roll / Heavy Metal sounded great. I tested it out on the Hip Hop channel, where it really hits pretty hard. Country and all other music sounds great. If you want to make the neighborhood hate you, spend the money on a 1000+ watt amp and a set of 15"s! If you want plenty of bass to ENJOY your music, this sub will work for you!

Subwoofer Upgrade for my 03 Subaru Forester 2.5XT

Written By Bobby, Newberg, Oregon on Sunday, May 27, 2007
 
I installed a factory subwoofer a couple years ago. The factory subwoofer is okay, but lacked power... I always wanted more power!

The Kenwood KSC-SW1 fits under the passenger seat where the factory subwoofer was installed. Instead of using hardware to mount the subwoofer, I glues strips of velcro (hook side exposed) to the bottom of the subwoofer. The velcro attaches nicely to the carpeting & makes for an easy installation!

To make the wiring of the Kenwood KSC-SW1 easier, I purchased an adapter on the internet so I could plug into the existing factory subwoofer wiring. In addition, I added a switch to turn off the subwoofer (blue/white power on lead). When I listen to talk radio, the subwoofer is not desirable, so I can flip the switch to turn it off & not have to fiddle with the remote control. I used the provided velco tape to mount the remote control to console, near the emergency brake.

The Kenwood KSC-SW1 is an improvement over the factory subwoofer, with nearly twice the power. The subwoofer will not rattle the windows, but it will be enough for most people. The installation was very easy... almost fun!

2nd time - for my wife's car

Written By grookes, Hayward, CA on Friday, May 25, 2007
 
I think I already have a review in here for my installation in my 2002 Honda Civic Si. I like this unit so much I bought another one for my wife's 2007 Toyota Matrix. I'm actually a little envious that it fits better under the Matrix seat (sits parallel with the back seat, resulting in more foot room for back seat passengers). In my Civic I had to put it in parallel to the door.

System sounds great as ever. My Civic has an Alpine headunit with RCA cables, hers has the Hi-Def JVC with RCA's. Best Buy installed it for $50.

As I think I said in my review for my Civic (about a year ago), the sub won't vibrate the car next to you, but it's sure cool having it under the drivers seat and hearing/feeling the music right there. For a perfect blend of space conservation and low-end, I have no regrets on getting this unit.... again.

The type of bass you get from your component subwoofer doesn't depend on the woofer alone. You'll need a strong, tightly constructed enclosure for optimum subwoofer performance.
