Resolved.
The output on the sub, when hooked to a front channel was very loud with the sub knobs on 5% volume.
I was testing everything with the knobs turned down since I was getting obvious output from the incorrect channel.
Once I adjusted the knobs to 50%,with the sub attached to SW output I got output.
Yeah...it was as simple as that.
To all the contributed, I am so very thankful for your time.
