Hello All I have a Yamaha RX-V863 HTC and a RCA PRO-SW60P 60-Watt Powered. Subwoofer. I have for a very long time been trying to connect the HTC to the SW with no luck. It seems the HTC has only one rca Fem for SW and my SW has a dual neg and pos rca fem's along with right and left high freq pos and neg speaker connections. I have tried multiple way to connect but nothing seems to work. if anyone has any suggestgions i would grately appreciate it.
