FEATURED REVIEW9/6/2022Boom Stage 2[This review was collected as part of a promotion.] I don't understand all of the negative reviews. I had the stage 2 Boom installed on my 2020 Road Glide, it is great I never have to turn it all the way up. No mater how fast I'm going I can hear it, it is crisp and loud. Others ride beside me to hear it everyone says it sounds great. It was installed 2 years ago by the dealer ship that I bought the bike from, I feel that is the key to my happiness. No problems. Sounds great. read more.

FEATURED REVIEW12/8/2020I agree with Mati O[This review was collected as part of a promotion.] I have a 2017 RGS and put in the Stage 2 audio system, which i installed myself, and it sounds great to me, a definite improvement over the stock system. I'm not sure what people are expecting when your riding on a rural road or even worse, the interstate. Your not inside a vehicle where there's no road noise. If you know anything about car audio the more you push a system to make it louder so that you can hear it the more likely your going to push the speaker into distortion, thus blowing it. It's not like your pushing 2000 Watts with sub woofers read more.

FEATURED REVIEW7/26/2020Blown speakers at twice the price!I had the stage II Boom Box package installed 4 years ago. It was working, but I was getting loud pops from the speakers. The dealership recommended to “Flash” the theECM and that would fix it. It did, the unit only created haft the volume, great! Now one one of these cheap speakers is blown and I have to replace both! I’m going after market. The local stereo shop is going to replace this setup. I recommend to NOT buy the Boom Box stage II package, you can do better with none Harley equipment. read more.

Its so sad that as much money that we spend, Harley can’t get it together to prefect the craft for the speakers and amps. I legit have had two cases of blown speakers recently for my stage two audio and I will never recommend Harley audio to anyone!!!!!- New York, New York10/11/2020

After reading everyone else’s comments I had to come in as well the amplifiers in the audio stage two boom system are despicable this is my second time replacing them at $445 per amplifier plus labor Harley can do better than this.- Inglewood, CA10/7/2020

Go with Rockford Fosgate. It comes with a 400 watt amp. Works great on my street glide.- Florida10/7/2020

FEATURED REVIEW7/13/2020Blown Speakers[This review was collected as part of a promotion.] My speakers were blown within 2 years.. I will never purchase Harley Brand audio again.
-
I had a very similar experience- at the nearly the 2 year mark I noticed distortion in the left speaker and shortly after the speaker was done and this mainly short casual rides to work. Never again! Is the HD stamped Rockford Fosgate audio suspect?- TX8/28/2023
