    Great product

    Nice amp for my road glide, for never installing a amp and speakers I have to say with all the planning they put into this amp and plug ins my job came out looking like it was installed by professionals, they thought of everything to make it easy for installing and setup, it’s also a low drawing amp that plays louder than I can take and my speakers are still in the safe rang. Just have to make sure you run the correct rms so you don’t fry anything

    Good refurb'd amp for '16 Harley Road Glide

    Shipped quicker than estimated. Came shrink-wrapped with all the parts, but in a generic box. Very small scratch on the face, although superficial and not noticeable. When installed in my Road Glide (using RF install kit) everything worked. Paired with four Polk MM652 speakers, and tuned properly, this amp rocked it. It's been installed for a couple weeks now, and riding everyday, I keep the volume at 3/4 or higher. No overheating, clipping, or distortion. There's always the concern of buying anything refurbished. I may have gotten a good unit, but I'd say it's for half the price of brand new is well worth it. It gets my recommendation.

    Great amp for motorcycles

    Small form factor and has cooling fans which is good when installed in motorcycle fairing. Only tested for one week but great sound so far. Almost impossible to run this thing full blast as the sound is really loud. But you can if you wanted to, no distortion if setup properly.

    This amp sounds amazing I have it powering all my door speakers that are Rockford Fosgate as well. Easy to tune for input and output.
