  • Good value

    ive went through several cheaper amplifiers before deciding to buy this one. All of the other ones suffered water damage from running through creek crossings and such on my side by side. This amp seems sealed up quite a bit better than the cheaper competition. And it has plenty of power and the sound quality is good. I wouldn't recommend the Pyle and Boss marine amps. But this Kenwood seems to be a much better product.

  • Exactly what I needed!

    This amp is perfect for my Street Glide. It is small and plugged right in to my Aquatica aftermarket stereo with included RCA cables. It has four channels and really brought my system to life. I replaced the factory speakers with 6.5" Polk Audio marine grade speakers and put Polk Audio marine grade 6x9's in the saddlebag lids. The sound is night and day. No more washed out sound with little bass. Now my bike sounds like a car with rich sound. I was looking at an Arc Audio system with 6.5" speakers and a 2 channel amp for around $450. I pieced together this amp, 4 speakers, and new pre-painted saddlebag lids for just over $400!

  • Excellent Amp for the money!

    I installed this amp into my 1995 Harley Davidson Electraglide Ultraclassic after upgrading the sound system to a Sony/Retro-Radio kit. This setup needed a little more punch, and after researching different amps I settled on this Kenwood. It fit perfectly under the outer fairing with Velcro tape. The RCA connectors made hookup a breeze. Sound quality is very good. Before installing this amp I had to turn the volume almost all the way up just to be able to hear the music while cruising down the highway. With this Kenwood amp installed that's no longer the case! I can turn the volume a quarter way up and hear my music clearly. I highly recommend this amp!

  • Super small with big crisp sound.

    Kenwood products are high quality and last for many years. This amplifier, though small, produces quality and crisp sound working in many types of vehicles.

  • Good Quality With amazing sound

    Works well with 4 - 6 1/2’s Pioneer three-way speakers & 4 Dome tweeters . With my rockford Fosgate 500 W monobloc amp . Pushing a 15” L5 Square speaker . With a CLARiiON passive equalizer .to level out the sound Between the subs and the highs sounds great

  • Nice little amp for your motorcycle

    I have a 1996 Honda Goldwing. I upgraded my speakers but the factory amp is just underpowered. I didn’t want hack up the bike and so that fact that this AMP can do speaker out was appealing. Also, factory radios don’t have RCA out. Nice clean sound and does the job. My only gripe is that when they say its speaker out ready, they don’t Supply the cables. You have to hack the end off the RCA cord and match that to the speaker wires. RCA cables like this have very little wire and it’s delicate work. I ended up finding the thickest one in my house and hacking that up. Also, the one in the box is pretty short so I needed a longer one. Happy with the result

  • Kickass Kenwood

    Nothing less than "HI QUALITY", I put it in my motorcycle to power 4 speakers with music supplied by my XM radio. It works great and sounds great. It has enough power to aggravate every car anywhere near me. I love it!!!

  • Handlebar controls

    Head unit sounds great. Easy install but never could figured out the wiring for the hand controls. I'm not cutting into the main wiring harness then to discover that didn't work. It's definitely not plug and play.
