Subwoofer hunt

Thanks guys for all your inputs. However I still have one more question :) promise this would be the last. 

So if I plan to just connect "ONE" sub for now. and if I still want to go with the high level inputs and not the pre-out from the sub how do I connect since there are two channels out there left and the right. Which one would I connect to?

@spoutjack -
I expect there will be 2 pairs of speaker level/high level inputs on the sub. A pair (+/-) for the left channel and a pair for the right. Check your sub mftr's. info. to confirm.

@bob_reynolds 
Good suggestion on the 2 way banana plug.  I'll take a look at that.
We ain't all that particular about things that don't make an audible difference.  Exactly how stiff is that Belden 12 gauge?  Not like coat hangers, I hope.  I might need to make a 90 or 180 degree bend...but talking mid-length - not near an end, so the bend can be gradual.  Let me know what you think.  Thanks.
