    Great amp for Harley

    This is sold as a refurbished unit but if it has ever been installed, I sure can't tell it. It arrived in the original box, shrink wrapped, and in perfect condition. I hooked it up (right now I am just using 2 channels. Saddlebag speakers to follow soon) and it sounds great. Perfect for fairing mount on a 2014 and newer Harley touring bike.

    Disappointed

    The one I received supposedly new, was nothing but a noise generator. Maybe I just got a bad apple but I returned mine and picked up a 300/4...Slash that is
