Just so disappointed with purchasing the S32 Sound Extreme sound bar and the Sound extreme receiver. I have a golf cart that has 4 sound extreme speakers and the S32 Sound Bar and was told all can play the same music which is NOT TRUE! I have tried every possible connection and nothing, it's either the sound bar plays or the golf cart speakers play but not both together like advertised! Called Technical support and got a woman that had no idea what I was talking about? Signed: Very Disappointed!
