Rated 2.6 out of 5 by 9 reviewers.
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
Rated 3 out of 5 by Good upgrade but it's not a big WOW! I researched and researched and decided I didn't want to deal with the downloads and issues people were having by installing aftermarket systems. A friend of mine upgraded his Boom Stage 1 speakers to Stage 2 and I picked up his Stage 1 speakers for $50. So I just went with the Boom amp and it does not mess with my warrantee. Otherwise, I would have gone with RF, Biketronics, Hogtunes, or J&M. I did get a decent upgrade going with Boom but I had to take the bike back because they dealer did not do their download right and it even blew my speaker so they had to replace it. Now, I have good volume and at highways speeds if I crank it just below 3 or 4 bars. It's a better quality sound (more clear) but I'm a little disappointed with the bass. The new download did improve my AVC and that works better then it did stock. Maybe the better speakers with more power helped me notice the difference better? I'm a real audiophile so I'm pickier than most but at the end of the day, it's still a bike right? All in all, I would do it again if I had the same deal on cost but for the money, I think they're better audio upgrade options out there cheaper than Boom. November 12, 2015

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.

I would like to have the Boom Audio upgrade (4 speakers and Amp) but I'm concerned about the power draw and I can't seem to find specific numbers.
