Review: 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.
Review: Crisp, Clear, Loud sound - 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!!

### ⭐⭐⭐⭐⭐ Incredible Amp! I couldn't believe the sound!
*by E***R on September 26, 2024*

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.
