I believe the Sub/LFE out on my Yamaha RX-V661 has gone bad.
I received a used subwoofer for temporary use and it would not turn green and play. So I connected my Aiwa's left speaker output to the high level inputs + & - and bingo.
So, it has to be my sub out or possibly the sub cable, correct?
How can I connect the sub without using the sub out on my receiver?
