Good Day.

I have a question about the stereo operation. I seem to be having inconsistant powering of my stereo. Is there a specific sequence is having it work properly? I put the ACC toggle on, then wait until my system powers up. The stereo always powers up, but sometimes there is no sound and sometimes there is. I have squirmed my way under the dash on both sides of the boat, but I cannot find any loose wires to fix the issue. Has anyone else had this type of issue, and if so, can you let me know how to fix.

Manitoba weather hot, calm and great for boating.
