Protecting the speaker cord, Technical Information

Page 10 highlights

Reference Protecting the speaker cord The bare ends of the speaker cord can be affected by exposure to the elements. This is especially true of salt water or water containing chemicals such as chlorine or fertilizer. You may use a silicone caulking material, such as RTV adhesive, to protect the connections. It is commonly available at hardware stores. If you do use caulking, apply it only after the cords are connected. Check the connections annually, and reapply as needed.
