I have a sailboat with the stereo and vhf down in the cabin. I have cockpit speakers and would like to use the same speakers for both vhf and stereo. I also wanted to be able to switch from the cabin to the cockpit so that I don't offend anyone while docked. The perfect solution would be to have two lighted switches, one left and one right, for the stereo to let me know when the cockpit speakers are on and one lighted switch to let me know when the vhf is operating one speaker in the cockpit as well. Can this be done without a lot of extra wiring?
