I was really surprised that one of these blew after about 20 hours of use (not hard use either, in my opinion). My amp is 120W / channel. The speakers have never seen rain. They were exposed to water once, when I washed the bike. It didn't seem to affect the operation. I sent an email to the company to see if I could purchase an individual speaker instead of another pair. I never did get a reply.
