Are the speaker original, if they are they don't like water on or in them.
Huh???? ???
I thought they would be water proof (marine grade) speakers. After all, they are out there in all weather.
I did pick up a inexpensive pair of marine speakers I'm intending to swap them out with, but only because of wanting something a little newer and hopefully better quality than 18 year old ones and 100K miles.
