I have a 1985 Catalina 22 and I am interested in installing a sound system. By far the most common setup that I see is to have two flush mount speakers installed on the cockpit wall from the inside, facing the cockpit. However, I really do not want to drill large holes in my boat unless I absolutely have to. What I would really like is to have a Bluetooth enabled box speaker mounted somewhere in the cockpit that I can have on an articulating arm, so that I could swing it out to face the cockpit if I'm outside, or swing it back inside the cabin if I'm inside. Anybody have any experience doing something like this? Or any other advice? I am not crazy about a car stereo to drive the sound since this is mainly for CDs and FM radio, neither of which I care about. I will pretty much only be streaming music from my phone.
