Thanks for your reply. My understanding of the pre-out was that it was only for dedicated LFE tracks in digital 5.1 media, not 2-ch stereo.
If I understand the three options, the third one sounds like it gives me the most use from the sub in that I could control the crossover and have it work "with" the mains more than just "in addition to" by using the line level. And I can just connect spades to the same terminals in addition to the bananas for the cables for the mains?
I fully agree on the diagram/schematic idea. Seems like something that could be pinned in the forum.
