I am ready to start wiring my HT from scratch. While pulling wire for wall plugs and pot lights, I was wondering if I needed to run a seperate wire (breaker) for the sub, (still choosing between outlaw, DSW 600, HSU) or my av (marantz 7002) or any other component. I usually put about 8 or 9 plugs on one breaker (15 amp), or do I just include them as part of the 8?

thx.
