Thank you. So you can run RCA to the bose system. Great! Exactly what I was looking for! I did not want to try and run all new speaker cables throughout the salon and stateroom. I like the way yours our connected so you can use either unit.
You can drop rca’s down the stbd wall at the helm and they’ll come out above the tv in the salon (sounds easy doesn’t it ) The rounded finished panel is held on using Xmas tree type clips. Hopefully your boat has pull wires in the walls it would make it a lot easier.
