Thanks for the reply, and sorry for the spacing. Poor formatting resulting from a copy/paste, and unintentional. I have edited the OP to fix that.

Anyways, I will need to double check on this when I am at their house later, but I am pretty sure the receiver/amp does not have A/B switching, nor does it have (I think) analog audio outputs.

Here are the specs on the receiver, maybe you can help me figure this out.

[Link: crutchfield.com] Incidentally, and I doubt it matters, but they are only using the Sub, front, and center speakers that came with this. The rear speakers are some recessed ceiling mounted speakers they bought separately.

Do we need to get a different receiver all together?

Thanks again!
