it's not the cable!!
Set cross over to 110hz manually, set sub to LFE+Main, still no sub in stereo. I thinking it might be the cable.
just to be clear, do not confuse the crossover setting on the sub itself with the bass management in the receiver.
On your BIC sub, when the switch is in the "Dolby Digital" position the crossover on the sub is DEFEATED and the knob doesn't do anything! That switch allows you to bypass the crossover so the receiver can perform all the bass management digitally. If the speakers are still set to LARGE in the receiver (which is the default) the SW will not get any signal with most programming material, regardless of what you do with that crossover knob..
So with the switch in that position (DD 5.1/6.1/.7.1), make sure your other settings ON THE SUB are correct (volume at about 1/2 way, phase at 0) and then run the AUTO SETUP and report back what the subwoofer volume level comes out at. You can just do a one-position run on auto setup to save time, the first position is where it calculates all the distances and volumes to balance the system, the other 5 positions are just refining the EQ filters.
Don't worry if the "thumps" from the SW sound soft during auto setup. Just do it and then check and see what the AVR sets your channel level on for the SW channel. And also make sure all speakers are set to SMALL with a crossover of at least 80Hz.
