I recently had a Pioneer head unit installed in my truck. My subwoofer and volume controls in the back seat no longer work now. I was told you need a special adapter to make these work. Is this true and if it is what kind of adapter and where can I find one? I'm also looking for some new speakers for my truck if anyone has any recommendations. I'm thinking of getting the infinity reference 6812cf's or Kenwood excelon kfc-x680's. Let me know what you think. Thanks for your help.
