I read your post about the surround sound. I have a question about my sound system. I am not sure if mine is working correctly. When I play the dash radio everything works through all the speakers, when I play a movie on the DVD player all speakers work fine but when I play music through the satellite from the tv the sound is low and nothing like it sounds like it does through the dash radio or DVD movie. Is that the way yours works. I expected it to come through just a strong no matter what I play the tv radio or dvd. The original owner of the coach replaced the original tv for some reason. Any help is appreciated
