    • Incredible Amp! I couldn't believe the sound!
I purchased this amp because I was adding a subwoofer to my boat. I have a Fusion UD-750 with 2 Fusion speakers and have now added a 10" Fusion subwoofer. I decided on this amp for the job, and I'm so glad I did! It fits in tight spaces and literally packs HUGE sound! I highly recommend this to anyone who is challenged with space and doesn't want to sacrifice sound or power. ... show more

My music used to drown out at 40 mph on my Harley. I have the Rockford Fosgate head unit, 4- 5.25" speakers and 2- 6x9 speakers. The install was clean and easy. The amp size was perfect. My music is now louder and more clear than ever. The input and output clip settings are in the amp. I did not have to buy a sine wave meter. I just cannot believe the sound!! Crisp throughout the highs, mids, and lowers. Definitely can hear it on the interstate now. Thank you Rockford Fosgate for another great product!! ... show more

    • Love this amp.
I had the same amp on my last street glide. Loved it so much I bought the same one for my new bike. Easy install and very user friendly for people like me who don't have a doctorate in audio engineering. Paired with some Rockford Fosgate 6.5s. Very powerful and great/clear sound at any speed.

    • Massive volume increase!
Installed this in a 2012 Harley Ultra, and paired with Harley stock radio (25w/channel), Hogtunes 2 ohm 6.5 front speakers (had to modify 5.25 mounts in batwing for them to fit), and 4 ohm 6x9 Polks in the saddle bag lids. I was amazed at the distortionless volume increase! Can hear the system clearly at highway speeds. The set up was straight forward but I didn’t receive the test tone cd needed to set the gains. There are multiple websites with free test tones that you can download to your smart phone or cd (in my case) or just set up with music from your radio. Also, the “auto-on” feature that was supposed to work with line-out setups with the radio didn’t, so I had to connect the “REM” input on the amp to a 12v source (cigarette lighter in my case), to get the amp to power up. Not a big deal, but just an extra step. Only have used this for about a month, so not sure of long term reliability but so far, it’s great! ... show more

    • Great amp
I used this to replace the crappy Harman Kardon amp on my 2012 Street Glide. Super easy install if you’ve ever had experience installing an amp. I’m using the high pass filter to run 4 speakers and it produces a ton of sound with very little use on the gain. Plenty of power left to upgrade to better speakers. ... show more
