I have this idea that I would like to install speakers on my 2013 Slim. At the dealers the other day I saw a Boom! Cruiser amp and speaker kit on display. I checked it out in the catalog and of course it says it will fit every Softail EXCEPT the FLS. I wonder if the reason is the Hollywood bar or if there is some other reason. Anyway has anybody else installed these or some other speakers on their Slim? Pictures would be great. Thanks much.
