75 watts
Total RMS Power Handling
This is the total RMS power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total RMS power handling for all of the subs combined.

Amazing for it's size!

July 28, 2014

I bought this to put under the seat of my 2013 Mazda MX-5 Miata but it did not fit. I ended up placing it right behind my seat and I am completely satisfied with the results. Considering how small it is and how little room it requires, the sound is phenomenal! I couldn't be any happier. I ended up connecting this via the fuse box (accessories) since it uses less than 10 amperes. My rock music sounds great with this! Again, I could not be any happier with the results. :) I have this hooked up to a Kenwood head unit BT318 and via RCA cables (Rockford Fosgate). This gives me the missing bass I needed and I didn't have to sacrifice my trunk space. Great job. Possible con: Provides great bass for its size but if all you want is window rattling bass and you have plenty of room for a powerful large sub then that may be a much better option. This is for those of us who do not want to or cannot install such a large subwoofer in our car.

Kenwood KSC-SW11

July 4, 2014

I bought the Kenwood for my Toyota Corolla, I had already replaced the front and rear speakers and stereo. The stereo and speakers made a difference but I wanted more bass to complete my system. The Kenwood KSC-SW11 had good reviews for its size so I ordered it. Installation was easy, mounted the sub under the drivers seat and ran the wiring along the door and easily found a ground and ran power up through the dash and tapped in to my stereo cable. The remote is nice and plugs in to the sub and routed it to my console. The overall sound was balanced out with the right amount of bass. If you are looking for a loud thumping subwoofer this one is NOT the one but if you want a balanced sound for your stereo then buy the Kenwood. The subwoofer comes with the wiring harness and installation is easy, I would recomend this amplified subwoofer to my friends.

Nice sub for basic system

May 28, 2014

Needed some additional bass for my system, which was running four 6-1/2" coax speakers, one in each door. Mounted the Kenwood sub under the passenger seat of my '13 Impreza sedan, fit perfectly. Ran two RCAs from my Eclipse head unit, and powered it from the battery using the supplied yellow power cable. The remote has a handy volume control and cross-over is adjustable; I set so the bass notes appear to come from the front speakers. The low bass effect is very subtle on some jazz cuts, more apparent on country, rock and hip-hop. At Sonic's discounted price, this unit is a very good value and since the built-in amp draws only 8 amps maximum current, can be handled easily by the Impreza's puny electrical system. Overall, a great product.

Kenwood KSC-SW11 Very Noice!

March 14, 2014

I have a 1986 BMW 635csi and the only space available to mount a sub was on the rear deck, because I needed to keep my trunk space free, and the KSC-SW11 was a perfect fit. The unit is built solidly, with the quality you would expect from Kenwood and was easy to install, I just needed to buy the RCA cable separately. Performance-wise, I like balance in my listening experience and the Kenwood provided me with a smooth, deep low end, that was easily tweakable to suit my taste, song to song. Sure, it won't shake you're fillings loose, or provide defibrillation if your heart stops, but it provides ample vibrations for a large range of musical styles - from classical, to Rock, to R&B & Rap - in other words my Telemann sounded as good as my Daft Punk, as good as my Springsteen & Jay Z, NWA, and so on. The KSC-SW11 delivers!

Great product!!!!

February 9, 2014

I purchased this product from Sonic online.. Fast and smooth transaction. Fast shipping... Product arrived mint.... I had it installed in my 04 gmc sierra extended cab, to my jvc head unit with preamp outputs... I also had new Kicker ds 6.5" and ds 4"x8" installed in doors.. These are low budget line speakers, but they are AWESOME!!!! Great for handling bass for rock music.... With the kenwood kscsw11 installed this makes for an incredible upgraded system... They mounted the kscsw11 on the tranny hump under rear seats as far back as possible... Not even visible... I get serious thumping for my bass... I had to turn down the bass control to about 30% on this unit. .. I found this to be perfect for Rage, Metallca, zombie, Manson.. Etc... It does exactly as most reviewers state in that it adds the missing low end thump to a system.... It worked so well I ordered a second one..... From another online dealer because sonic was out of stock... I had this one installed in my sons f150 super crew cab, under the passenger side front seat.. It does a decent job with the factory unit and speakers, BUT nowhere close to my gmc with jvc head unit and kicker speakers.... So my suggestion is...if you feel your factory system is a little under powered after installing the kenwood kscsw11 then get a new receiver and door speakers to match output of receiver if you can afford it... Otherwise if you only replace the receiver you will definitely blow your factory door speakers like I did in my gmc.. Gonna put a head unit in f150 and post results later..... But overall the Kenwood kicks butt for the money..... It doesn't give the obnoxious low end bass that shakes the neighbors windows , but it's perfect for rounding out a factory system to add a good thump.

alot of punch for a slim sub

November 11, 2013

just had this subwoofer installed and it sounds great. price was good value for what your getting. I had to keep it under my drivers seat to get best results from it. if you place it far away from you, you will loose the effect.

Perfect for my short cab Ranger

September 17, 2013

I needed to add a bit more bottom end to my system but had little space for a sub. This fits perfectly behind the front (and only) seat. It is crisp and punchy. I don't rock out much. Mostly Jazz, talk radio, and various CDs. I love this thing. I have listened to some Stevie Ray Vaughn recently and I really cranked it up. It sounded great to me. I also like the remote, which makes it easy to transition from one type of music to another without having to go into the settings on the head unit. Time will tell on the durability of the sub, but I suspect it will be fine as I've always had good luck with Kenwood products.
