Rated 2.7 out of 5 by 10 reviewers.
Rated 4 out of 5 by Stage 1 I had the dealer install the Stage one amp and speakers last year. All I can say is that has been a good system. I have had zero issues with it and it sounds great and clear at any speed. September 27, 2016
Rated 1 out of 5 by Very dissaointed Don't wast your money. Nothing but problems with amp and speakers. Thought I was doing good by buy Harley, should have gone aftermarket less money better sound March 10, 2016
Rated 5 out of 5 by Excellent Sound!! I decided to upgrade my Street Glide Special sound system to the Boom Audio Stage 2, I purchased the fairing amp and speakers from my dealer because they had a special on them, after I made purchase, I started to read all the reviews and most where not very good, I was going to install it myself and take it to the dealer to flash the radio, but after reading all the reviews and talking to a service advisor at a dealer, I decided to let the dealer install it. I just got back for a 250 mile ride today (unseasonably warm today in N.E.Ohio) and I could more happy with the sound and the performance. Anybody making the purchase, have the dealer do the install and you shouldn't have any problems, I know there are a lot of aftermarket choices, but I like to stick with the factory OEM equipment.

Rated 1 out of 5 by Unhappy with Boom II Audio System I installed the complete Boom II system (FR & RR amps + FR & RR Boom II speakers, Amp install kit & high output charging kit). Over $2,500 + the cost to have the dealer switch the EQ software. At first I was happy with the system, but then I started having clipping/popping in the speakers when ride and sometime the front amp pops the breaker (reset) also when riding. Tried lowering the bass level, but still had the same issues. All these problems are only when riding. I've been considering removing the whole system and going to a J&M system. I have not contacted the dealer because I see others with the same problem and because I installed the parts myself (they may say it was something I did). November 28, 2015

Connections on 2016 triglide

Are all the connectors for amp there ? Do you need to run separate power line back to battery or are all the wires there around the radio ?

Answer: 
No, you need the second amp, the correct way is to put one amp in the front and the second amp in the saddle bags. Very little space is lost.
