I've got it on my SG, sounds very crispy clear. You're able to hear it at highway speeds. I don't want to start an amp arguement that this one is better than that one and that one is better than this one, but a buddy of mine has another brand amp and even himself says the BOOM AMP sounds much clearer than his. Also want to mention I upgraded to the Boom speakers turned out to be a perfect combo. I'm very satisfied with the BOOM system.
Thanks for the info. I'm looking at getting an amp in the future to improve highway sound when I ride, but have'nt decided on anything yet. this info was helpful.
