I would like to continue to utilize the 15 amp stereo breaker on the panel as it's currently 15 amps for the stock HU. My hope is an adjustment can be made at the harness or panel level to accomplish this.

Thx
What year is your boat? Are you sure the 15S stereo breaker is not already a constant 12V when the main battery switch is on? With that said, if your boat external amps, i would not want to use that helm panel breaker anyway. Easy path to unwanted noise.
