My Harman Kardon AVR-130 volume decreses 45 min to 1 hrs after been turned on. Can you advise please.
Check the impedence you amp.s ohms or probably lower then the speakers you are using.alower ohm amp will blow a higher impedence speaker.a lower ohm speaker will burn a higheer ohm amp.make sure ur amp. n spkrs are the same impedence.
So, what seems to be the problem?
