It would work better that way but unless you want to take the effort to rewire then you are stuck with it. The radio in the bedroom on mine plays in the bedroom and the outside speakers. I really didn't like that until I hooked my iPhone up to the bedroom radio via bluetooth. Now I can play music from my iPhone when we are sitting outside and can even control the volume. We seldom use the dash radio. Sometimes use the bedroom radio for the outside speakers via bluetooth from the iPhone so we are OK with the setup.
