It's been a long time since I have done much with my home theater. After moving 3 years ago I still have not hooked up my surround speakers because of placement. I've finally decided to get some in ceiling speakers for my surrounds, and I want to future proof myself. I will only have 2 surrounds today because my older receiver is only 5.1, but I'm thinking it would be smart to have extra wires run at the same time to cover an upgrade in the future. Do I go with 3 for 6.1, or 4 for 7.1? What do most people do now adays for surround speakers?
