    4-Speaker Ultra Boom! Bagger Kit is rated 4.5 out of 5 by 4.
    Rated 3 out of 5 by from Works when it wants to I have a 2011 FLHTK with the boom system that was on it when I purchased it. It was put on my a Harley dealer. It has a broken wire in the harness some place and only works when it wants to. I have no sound 50% of the time. When it works it's great. I took it back to the dealer that installed it and was told that it was installed by techs that used to work for the previous owner of the dealership and the only thing they could do was put an entire new harness on. Not very happy with it......

    Rated 5 out of 5 by from Excellent sound I wanted new speakers for my bike but didn't" want the amp in the tour pack. Talked to my dealer (HarborTown) in Manitowac WI and said they could install a street glide amp. By moving the CB unit under the radio they could mount the new amp above the radio. Turned out great and no amp taking up space in the tour pack. I can now run down the interstate and hear my music without having to crank it way up unless I want to

    Rated 5 out of 5 by from ULTRA BOOM! I was always using the headset for music due to the lessor quality of the stock system. Had this kit installed during winter storage at the dealer. Wow, what a difference this year. Sound quality is much improved - better bass response and less distortion cruising at town or highway speeds. I won't say concert quality sound, but it's on a cycle and weather resistant. Excellent upgrade if you really like to listen to music.

    Rated 5 out of 5 by from boom on I recently put the Boom Audio Ultra Bagger Kit on my 2012 Ultra, wow. I did a lot of shopping and what sold me was a Harley display at the Denver Motorcycle swap meet. I was sold. When I got my bike back I was very impressed with the sound quality, standing still or in the garage it was like a concert hall. Very good listening quality at high speeds as well. There is not much we can do when mother nature throws us the big wind, that is when its time to plug in the helmet. Very happy with the purchase and would highly recommend it to anyone who has an ear for crisp listening , even at highway speeds.

    Q & A

    Alternator upgrade and Aux input

    I am planning on upgrading my 2013 Ultra Classic with this system. Will the stock electrical system handle the drain from the amp or is an upgraded alternator also recommended? Also, after reading some of the other questions, just want to make sure that I will get the benefits of the upgrade when using an MP3 device plugged into the Aux jack on the head unit and not just with the radio/CD.

    Asked by: Nummy
    Hey Nummy, This kit comes with the Boom!™ Audio Tour-Pak® Mounted Amplifier, so the amp is for the tour-pak. Thanks! Rockstar883

    What calibration is required

    What calibration is required for this system that I can not perform?
    Asked by: Richie64
    Hi Richie64, If your motorcycle already has 4 speakers (2:Fairing / 2:Tour-Park), a calibration is not required. Thank you for your question.

    Does it come with the wiring harness to connect the amp to the head unit?

    It appears to come with the mount for the amp, but what about the necessary wiring harness? I have a 2008 Ultra with the advanced audio system. Thanks!
    Asked by: Jb7705
    Hello JB7705, There are no additional wiring harness required for your model. These are ready to install. Thank You!
