A A A

Add a custom sound system to your King-size windshield-equipped model. This Boom!™ Audio Cruiser Amp and Speaker Kit features a stylish black and chrome enclosure that mounts to the inside of the windshield, and because it rests below the cross brace, it maintains a low-profile appearance.

  • Waterproof enclosure conceals the great-sounding 3.5" speakers behind a rich black grill, and the surrounding chrome band adds a stylish finishing touch
  • Compact two-channel, 40-watt stereo amplifier mounts out of the way on the frame down tubes
  • The 1/8" (3.5mm) stereo auxiliary input connects to most portable audio players, some of which can be easily housed in a convenient Boom!™ Audio Tank Pouch
  • Integrated hand control features volume up/down buttons and a backlit on/off button, and is designed for easy operation with your right thumb, even while wearing gloves
  • Complete kit includes all wiring and mounting hardware

Rated 3.7 out of 5 by 10 reviewers.
Rated 1 out of 5 by Where is the bluetooth and usb? For the price I think you have a usb connection for your ipod and bluetooth. This thing in outdated by ten years. Other competitors offer a lot more for a lot less. Handle bar controls only has buttons for volume control and power, no way to change songs. August 22, 2016
Rated 5 out of 5 by Love this speaker! I have this installed on my '14 Softtail Slim. Looks great and I love the fact my handlebars aren't cluttered up. My bike has been outside in a couple of nasty downpour rainstorms and the speakers are definately waterproof! I have ridden on very windy days going 75 mph on the highway wearing a helmet and can hear my music just fine! I absolutely love my speakers! I do wish that it came with a shorter cord to plug into your mp3 player along with the super long one that comes in the kit. I definately reccomend this windshield speaker kit! July 3, 2016
Rated 2 out of 5 by boom cruiser speakers On a scale of 1 to 10, I give the design a 10 but the quality a 3. It sounds great when your in town or at a traffic light,but on the highway at 70mph you can barley hear it.If you have alittle base in your music it gets distorted.I really expected better sound quality.But I love the way it fits my 2014 FLSTCI April 15, 2016
Rated 4 out of 5 by Boom Cruiser Worth the money I've had other after market stereos on my 2007 Road king and so far this one has held up and sounds the best. I do wish it was a little bit louder on the interstate but you are still able to hear it. I installed it myself and have had it for two years now. Getting Harley brand is worth the extra money you might pay out compared to other stereos systems like this. CONS: No Bluetooth Could be a bit louder. March 30, 2016

Is radio included in this system

I would like to know if this system includes a radio tuner, or is it strictly for smart phones, IPods, Sirius, etc., as I like to listen to local radio stations at times.
