Wet speaker cables

Put them out in the sun for a several days. They should dry out and be fine. I assume they have a sheathing around them

Wow water and electricity dont work well together..I would replace them. If it were my syatem I wouldnt even consider using them.

I will definitely have them tested at my dealer rather than putting my electronics at risk. What do you think my insurance company will say about replacing "wires" that cost $xxxx?

If water has seeped into them they will corrode which will effect their performance. Especially if the ends got wet. You should be able to see the corrosion setting in at the bare ends. In the mean time you can use them as the very high resistance of the water is no where near the much lower impedance of your speakers.

BTW, Bose use to hook up there outdoor waterproof speakers and immerse them into a bucket of water while playing to prove there waterproof status.
