Looking for a sound system for my 2011 Heritage. I have heard the Boom system in the HD dealership but of course that is in a building with no outside noise or 70mph wind. They did sound really good though. Problem is I cannot find anywhere the Watts of the Boom setup. Anyone??? I have also been looking at the 150w per speaker set up from DMG (online). Just a tad cheaper but with 300 total watts, I have to believe it would sound pretty good at highway speed. Input?
