I have been doing some research into installing a complete new audio system in my 02 TJ, and a thought just occurred to me: I have seen a lot of posts about the marine grade Polk speakers (which I am considering especially for the dash because of proximity to rain), but nothing about the head unit with regard to weather/humidity. Since I will most likely be running my TJ 6 months of the year with nothing but a bikini top, and I don't have a garage, will general humidity be a problem for the head unit? I know there are marine grade receivers but they are limited in choices. Thoughts?
By the way, I live in Pennsylvania, and humidity levels are fairly high through the summer.
