I'm in the same 'boat' as you JB. Unfortuantely I have to park the boat outside, and haven't had an issue with my speakers yet. BUt, I am also waiting for them to have an issue so I can replace them. I can't justify replacing perfectly good speakers... well, I suppose I can since I replaced the cabin speakers this year, but still...

I'd like to make some speaker socks just to protect them a little...
