For the rear,just a pair of DB Coax,will be plenty enough, and sound good as wellHmm, surround effect, huh? I think that's what I was really asking about. I didn't know if that was a real, desired effect. Or if it just made things more complicated than they needed to be. Which set of polks would you recommend for the task? Here is my amp:
