My wiring now - sub output split from receiver to rp5 LFE's. speaker wire to high input without gold straps attached. I have trouble with the subs not kicking on in auto mode unless the volume is high. I also get humming when the receiver is shut off. The rp3's are speaker wire only and the gold straps are in place. I don't have trouble with them. So, is it better to just use speaker wire and bridge with the gold straps? Or use the sub output on the receiver? Also, I have an extra pair of rp5's in great shape. what should I ask for those?
