I want to wire in a toggle switch for each one of my amps on my boat. I have four separate amps. I want to be able to shut off or power up each amp when I want to. For example....my sub will be on probably all the time unless I am tuning the sound system etc., but the tower speakers, the cockpit speakers, and the cabin speakers are all on separate amps, and I don't need all of them on all the time. If I wire in 4 separate switches on the remote wire this should be fine correct? Now if they have an LED in the switch will it cause any feedback or noise? Or any other problems?
