These are all great advantages, but what is the downside? As one offshore boatbuilder put it succinctly, “I don’t like to put so many eggs in one basket.” And that’s a valid point, especially if integrating the audio system means you eliminate a dedicated source unit control on the bridge. If a display goes down, so does music control.
Until recently, Polk audio systems did not integrate, yet yachtbuilders still selected them. This is partially because their unique source controller is waterproof and very compact, yet robust. It is an easy matter to wire relatively inexpensive controllers or remotes in each area, creating redundancy and the ability to control volume in a particular area, and it is done without tapping the NMEA 2000 bus.
