If you’re thinking of buying a subwoofer for the first time, you might be overwhelmed at the sheer size of the market these days.

There are, in short, a huge number of subwoofers for sale right now, and it might be difficult to decipher which one you want if you don’t have experience in the field. If this sounds like you, then the Kenwood KSC-SW11 Subwoofer might be a safe bet. 

Tiny, easy to assemble, with a lower bass output, this product is a good match with for the casual consumer.

Kenwood KSC-SW11 Compact Powered Enclosed Subwoofer

With a recommended bass output of about 75 watts RMS, the Kenwood KSC-SW11 Subwoofer is really quite a tame model in comparison to the competition, which can spit out, on average, somewhere between five and six times as much bass.

This unit is powered, so users won’t have to purchase and install their own amps, and it’s also tiny, around five inches by eight inches total across the face.

Much newer models can cost a bit more than some are willing to pay, while older versions can cost half the price of newer models, which is much more reasonable.

This is a great model for a new user who doesn’t want a lot of bass, and also desires a great degree of flexibility in terms of placement within the vehicle.

Who is this product for?

Because this product has such a drastically lower bass output than some of its competition, this product is going to have to be for mostly novice users who don’t want a typical subwoofer. Most subwoofers have a watts RMS output of around or above 400. Not so with this Kenwood model, which has a max output of 150 RMS and a recommended output of 75.

That’s not to say that this is a bad value, though. There are a lot of good things to say about this piece. For example, it’s remarkably small, which is a great benefit and affords the user a lot of flexibility in terms of placement.

It’s also powered, which means that the user does not have to purchase or install his/her own amp. All of these features make this Kenwood product a strong fit either with a new consumer who’s just exploring the market, and/or an experienced consumer who just wants a little bit of extra bass in his/her setup.

What’s included

It’s quite simple to figure out what’s included with this product, since this Kenwood piece comes as a single unit, preassembled. Aside from the piece itself, you’ll find a remote control included in the box, which is a neat little perk to have included with the purchase.

Of course, the subwoofer comes with an amp, but this is already built into the piece itself. You’re not going to have a lot of assembly with this one, and you’re not going to receive a lot of parts or anything else right off the bat.

Overview of features

Size is a key selling point on this one, since the face of the subwoofer is only about 40 square inches, which is remarkably small. The remote control is a nice perk, while the unit itself will require little to no installation, since the amp is already built into the subwoofer itself.

The primary features of this Kenwood model are (1) the size—it’s small—and (2) the bass output, which is low in comparison to the competition. It’s not going to give enormous amounts of bass, but it’s going to be a huge upgrade on your car’s default audio system.

How to get the most out of it

One of the features this model has going for it is that it really requires no installation, and is very intuitive to use.

Users could also interpret this as a drawback, since they have very little control over the setup of the product, and are unable to determine, for example, what sort of amp it includes; the supplier does all of that for them. 

For better or worse, there are no tricks to get more out of this one, and installation requires little to no knowledge and/or effort.


  • Older models quite affordable
  • Little to no assembly required
  • Intuitive user-friendly design


  • Much less bass output than other models
  • Amp built-in, consumer unable to choose amp type/quality
  • Newer models are poorer value (expensive)


Rockville RWS12CA Subwoofer

This subwoofer gives users a lot more bass (about for times as much on average) and comes with a user-friendly assembly kit and installation guide. It’s excellent for the beginner user who desires a little more additional bass.

Skar Audio D4 Subwoofer

This model will give you almost six times the bass as this Kenwood model, and is a good option for those who really want to maximize bass output. Consumers will have to buy and install an amp on their own, which could be hard for a new consumer.


There are several different groups of consumers that might want this subwoofer. It’s a desirable product, and can add quite a bit of bass to a vehicle’s sound system with relatively little setup and installation required.

Users won’t get a lot of bass output with this product, but they also won’t have to go through the bothersome process of purchasing and installing their own amplifier. We should also make note of the prospect that many users simply desire less bass on their subwoofer. 

This Kenwood model’s lower bass output can be construed as a positive feature, then, under certain circumstances.
