I know both of my Yamaha recievers have a screen that allows you to set the LFE/BASS output to FRONT, SUBWFR, or BOTH.
Did you check that screen? I think when Fronts are set to LARGE and LFE/BASS is set to SUBWFR, you will only get LFE to your sub not bass from 2 channel music. You need to set BOTH or have your Fronts set as SMALL.
Just my 1st thought, after I read your post. Set it to BOTH even if you dont want to keep it there, just till you get the sub working.
**I guess I didn't read far enough. Good luck with the new sub amp. :-)**
