Front Speaker issues w/my '14 RZ2

[Robmc9]

Started to notice this past month, my front speakers crackling (stock for a '14 RZ2) when I 1st turn on the music, almost like they're blown (the crackling is very noticeable throughout the entire boat) but the fix has been to turn the volume way up then back down and the crackling goes away. I've checked the wires and everything looks like its connected properly (although I'm no expert on stereo fixes) and was curious on what others think I can do to stop this crackling.

Poorly fitted or dirty RCA connections at either the amp or back of head unit, can cause nasty noise. It also sounds like one of the amp POTS (tuning dials) has gotten a little corrosion inside on the contacts. This can sometimes be cleared up with some electronics cleaner spray and working the dial back and forth.
