What customers say about "Size & Weight"
Kenwood KSC-SW11 150W Low-Profile Amplified Car Subwoofer Enclosure+Amp Kit
  • Easy to install and very small; about the size of a 12-disc CD changer.
  • great sound under my seat that adds a lot of bass and lower frequencies to my stereo. And it is only 8" x 5" in size.
  • I was also surprised at the weight. It's heavy (which is good).
  • Compact and feels solid (i.e. heavy, not sure which part of it contributes to the weight)

What customers say about "Audio"
Kenwood KSC-SW11 150W Low-Profile Amplified Car Subwoofer Enclosure+Amp Kit
  • Its very handy for various music samples as depending on the quality the bass frequencies are either too high or severly attenuated.
  • This thing functions best on the very low frequencies. That's where it shines.
  • Hits the higher frequency bass well so it works exceptionally well for reggae
  • Does not do a good job with sub - frequencies. Does okay with low-mids. Doesn`t even compare with a small powered Bazooka tube I own, but considering the space issue, it`s probably the best option out there for a very limited application.
  • Does not hit real low frequencies Distorts easily if power is cranked up.

What customers say about "Features"
Kenwood KSC-SW11 150W Low-Profile Amplified Car Subwoofer Enclosure+Amp Kit
  • The remote comes in handy as well, you can adjust the bass level and frequency.
  • The remote for adjusting the level and crossover frequency does a good job. It can add bass when I'm listening to music, and take it out when I'm listening to talk radio.
  • Thank goodness it has a remote to control the frequency and volume.
  • I drop one star because it's impossible to control it without installing the wired remote control unit supplied with it: there are no controls for its settings built into the machine itself, and without the remote, it operates simply on defaults -- the wrong defaults.

What customers say about "Connectivity"
Kenwood KSC-SW11 150W Low-Profile Amplified Car Subwoofer Enclosure+Amp Kit
  • You can splice it into a speaker line for signal, or wire it into a head unit's sub/preamp outs. it even has a +/- swap switch, in case it (or your speakers) are wired in backwards.
  • Installation was a breeze. I did choose to buy an "add-a-circuit" for power from the fuse box. but it was well worth the 10 dollars for the time it saved me
  • The unit comes with a long length of wires all connected to the sub's wiring harness. It includes a fuse. You may need to purchase connectors or splice tubes if you need to cut the wire.
  • The controller comes with a ton of extra cord. Other than that, you can adjust it's activation frequency and gain (volume).
  • Didn't come with the mounts it was supposed to have. Looks really cheap as well as the wiring. Bad instructions
