I have a Klipsch sub 12 that I just purchased. I am using the speaker level inputs and outputs because my reciever does not have a sub out. I had the sub off and not on auto on and my wife decided to put the reciever on to listen to music. To my suprise, music started to play through the speakers and obviously not the sub because it was off. Should the speakers still work if the sub's amp is off? Could it damage the reciever or the subs amp if I run the reciever with the sub's amp off? Is this a stupid question?
