Hello, I have received good advice on this forum in the past so here goes... We spend time coving out in the Summer and half the people are in the water off the back of the boat while others stay on the boat. The people in the water want the music turned up, while the people on the boat want to talk and not hear blaring music. I had an audio company come look at adding rear speakers. They said they would add an amp and separate volume control with a pair of rear speakers. I liked this approach and believe it will solve my problem. Here is the issue, when they came to install they showed me their plan and I decided to wait until I got some input from others. Really nervous about cutting the holes they plan to do. Wanted some input. Their plan B was to mount speakers on the rear swim platform. Aside from being ugly that required drilling holes in the swim platform deck. At this time I am leaning toward some speakers on long leads that I can set and plug in on the rear platform when I want then put away when not using. Who has solved this problem and how did you do it? Thanks for the advise!
