I am looking to set up an outdoor theater on the bow of my boat and was looking for ideas. It's a large space because it is a catamaran, roughly 18 feet square with elevated seating over the salon windows. I was planning to get a 10' screen and project from the flybridge but need to sort out the sound situation. Ideally, I would have 5.1 and not having to run wires for the speakers would be ideal, but would consider it if sound quality and reliability dictate. The speakers would not be permanently installed and we would just break them out for movie night, although having a couple on the bow railing I could connect to the boat stereo when not using for movies might be nice. Any advice is welcome.
