When I turn on the power to the stereo. Regardless of input or volume get a super loud noise coming from both the port side speakers. They are vibrating like the bass is going and its pretty loud. We had heavy rain for the last couple days and the boat really didn't get that wet inside with the cover on. I did see moisture at the bottom of one of the speaker cones. Do you think it's just wet or is it the amp that's the issue? Not sure what to do other then let it dry out and figure it out. Will get it into it's winter spot this weekend but needed it at home for DMV and other stuff.
Any advise?
