Yes, I'm running the subwoofers from the "rear" output through 18 ga. speaker wire. So, I don't think I got ya there. Mains, are you referring to the actual wires? That would make sense because I have 10, count 'em, 10 DVD audio RCA outputs that are not being used. I described them in an earlier thread:

Front R+L(red, white)
Center Subwoofer(2, both black, doesn't say right or left)
Rear R+L(red, white)
Subwoofer(1, black)

That's how it's labeled. I don't know... I can't believe this has been that much of a task. I thought I would have this mo-fo up and boomin', even though it sounds great now, I need to hear what everyone is talking about, then make a more educated decision. Anyhoo, you guys are the kewlest.
