So I am wanting to upgrade my sound system but I am concerned about two major factors. One is I live in South MS where you can leave the house and the skies are blue and beautiful only to get 15 miles north and the bottom falls out and there you are, topless and soaked. It rains everyday during the summer, might only rain 5 mins, but that 5 mins can leave you with 5 inches of water. What do you suggest for sound? Also, what about security when the top and doors are off?
