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.

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.

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.
