Hello. im using a k8060 amp as a subwoofer amp but i’m getting some noise from the sub out rca connector on my yamaha reciver.
i havent grounded anything to the chasse of the subwoofer, maybe thats what i need to do.
The amp makes no noise when i plugg in my phone and play music with it.
Plus would it be a good idea to ad a preamp ex.k8084?
Suggestions??
