Nice sound!!
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.

Perfect Size
This is the perfect amp to replace a C6 Corvette Bose Amp. I have installation instructions on my youtube page, look up Phoenix21Studios. RF has been a brand Ive trusted for 20 years.
