Great for Harley with the money

It's a great addition to my RF "Stock" plug and play stereo set-up on my HD E-Glide fit under the Faring perfectly. 400Wx4 is just the added sound need with my love for load pipes.

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.
