i'm new to the outlaw family with a newly arrived 990. i've got B&W 805 for the front, B&W HTM2 for center, and three B&W SCM1's for the rear. I want to go to 7 channels but it may take a while to find another rear speaker as they sell in pairs (usually). anyway - what's the best way to set up with six speakers. i'm sure that i should have two to the sides and one to the rear, but i'm not sure how to connect the rear speaker. thanks!
