Very nicely explained.Yup, they will function during stereo listening as well. The pre-outs for subwoofer are different from that present for the Fronts. If you see below image under preouts there are 4 rca ports - "Bottom 2 for sub 1 & 2" , "top 2 for fronts (red for right front and white for left fronts).
When you get the PA , there will be 2 RCA ports on the same and you can just connect the preouts from your AVR to the Power amp , adjust power amp gain/volume and run audyssey. Then you are good to go.
