Onkyo 605 + Polk 6750's first time setup

[aramis109]

Ok, I'll preface this with saying my speakers haven't arrived yet.

That said, I know there are a lot of people on this forum with the same setup as mine for their home theater. What are some suggested settings? What are some things that stumped you and you'd like to pass on? What things should I know?

I'd appreciate the help- some of the 80hz settings and such confuse me. I'll be hooking up my subwoofer via RCA instead of messing with hooking it up to the center/etc. I want to make my setup go as smoothly as possible cuz... the wife is on the warpath about this new setup. I currently am using the TV's AWFUL speakers and she's not pleased. I can't hook up my old HTiB without a big hassle as the sub isn't powered.

Anyway, any help you guys can give is greatly appreciated.
