I have a strange issue with my '09 Outback Special Edition stereo-at random times while listening to a CD, or the radio, or using my mp3 player in the AUX mode, the sound will completely drop out. There is no speaker hiss-no audio signal whatsoever. could it be the amplifier crapping out? It will work again after turning stereo off and on, but for a nearly-brand new Subie is something that anyone else has experienced?!!
