I bought the amp in the summer, couple months ago. It worked great up until recently. For example, previously i would play loud music (volume level 45) and be able to hear it all through the house thanks to the 4 ceiling speakers i have installed. Now in order to truly play music at the same "loudness" as before, i have to turn the volume up to 60. Does anyone have any idea on why this might be?
