When I hook up the (Pioneer SW-8) subwoofer to the subwoofer port in the back of the receiver, there is no sound out of this port.
1. How can I verify that the port is not damaged or malfunction?
2. I have verified that the subwoofer cable and the subwoofer are working, is there any other way to test the output of the subwoofer port?
Thanks in advance...
