Thanks for getting back to me. I have an email in to Yamaha support regarding the sub connection. I will let you Know what they say. I will be unboxing and beginning the Install tonight, I only purchased one rca cable myself, so I will be connecting the sub in the same way you guys have for the time being. Was just recently told about the alternate connection method, and I thought I'd check here. If anyone has any tips or advice following their install, please feel free to share them! As I said, this will be my first real home theater setup and I'm hoping everything goes smoothly.
