hahaha thanks guys! This is great info.
I've actually been using some leftover 16 AWG monster XP originally purchased for the satellite speakers to connect the terminals on the C3, but it's always felt like a "hack." Using proper connectors and staggering them should help make it feel more official, and put my mind at ease.
I still have a ton of monster cable left over from college (I worked a stint at Best Buy, but I feel like I've forgotten more than I learned), so running lower gauge isn't really expensive
I've been running 5.1 for years, but I love the 7.1 setup. I tend to move every other year or so, and thus one of the moves I lost the connectors for the C3, and one place the living room was hardwood, so I stopped running the 7.1. But I'm in my own place now, and I'm tempted to hook it all back up. It's so fulfilling to hear PS4 or even blue rays move from one side of the room to the other across the audio channels.
