Rated 4.2 out of 5 by 5 reviewers.
Rated 5 out of 5 by What a difference. Just got my 2014 Ultra Limited out of storage at the dealership and had this upgrade added. Right from the beginning I knew the money I spent was well worth it. Although it is somewhat louder than stock, I can truly say the clarity and punch is a huge upgrade. The bass hits you squarely in the chest with excellent high end sound also. I can take the volume all the way up and the system has no distortion. I had kids in the car next to me playing along with a drum solo that was on the radio and they gave me a thumbs up. I would definitely recommend this product. March 18, 2016
Rated 5 out of 5 by Harley sure has worked on this problem I ended up with Boom Audio speakers on my old bike and was finally happy with the way music sounded at speed - loud enough and clear enough. I didn't hesitate when I outfitted my 2015 FLHTCU, and am I glad. This thing add's ton's to the stock 6.5 infotainment system. And the Bass blows you away when standing still on my 2015 the new enclosures around the speakers in front make a huge difference. Clear, Loud, balanced - good work Harley-Davidson - and easy to integrate as well. Beats the heck out of aftermarket solutions. May 4, 2015
Rated 1 out of 5 by $1,000, Speakers keep blowing On my Ultra Limited, I had the dealer install the full system. I wanted a little more sound for the hiways. I spent about $850. in parts, dealer discounted it, and about 200 to install. Less than a half a mile away, the first speaker blew out. Went back, he had to order another. Waiting a month, the second blew. I called the dealer to let him know, he added that to my order. The system did sound nice when it was first installed, alot clearer and a little louder, not much, but noticeable. Well before he got them two speakers in, I traded the bike in, and got a TriGlide. I lost all that money, without any pleasure. I would love to upgrade the TriGlide, but not at that cost, and BAD SPEAKERS. October 29, 2014
Rated 5 out of 5 by wow Really cleans up the sound quality of system on my 14 FLHTX. When doing my xm subscription over the phone the xm guy said wow that's a great sounding system for a motorcycle. He was even more impressed when I told him it was a Harley. It's not louder, just a lot cleaner and crisp. January 4, 2014

Auto volume control

I have a 2015 tri-Glide and when I purchase the bike I had the BOOM! AUDIO BAGGER AMP & SPEAKER KIT installed before i pick it up from the dealer and now the auto volume control will not work on the bike also when it does come on then I cant change the volume from the handle bars. Is this normal when you have the BOOM! AUDIO BAGGER AMP & SPEAKER KIT added??? If so what can I do to get this to work? $1000.00 is a lot to pay for something that does not work!!

Answer: 
Hi Oneup,

Unfortunately, no, the Boom Audio Stage I Amp in this kit will not power the Stage II Speakers. If you were going to install Stage II Fairing Speakers, you would need the Stage II Fairing Amp kit, P/N76000278,

Thank you for your question.

you stated:

"The 54-Amp High Output Charging System P/N 29900028 is a recommended install anytime a multi-amp audio system is installed in order to achieve the full capability of your audio system."

If I'm understanding this right, if I use only one Boom amp and 4 speakers, then the charging system upgrade is not a requirement on a 2014 FLHTK?

If I run more than one amp, then the charging system needs upgrading from the stock 50amps to 54 amps.

is this correct?
thanks
