Help, I hope someone out there is running 2 HGS-12 subs in their system. I need help on how to hook my single SW output to 2 of them. The HGS-12 has a left and right line input. I know I can split the output of my SW but does it then have to be split again to go into both the L and R Line in to the sub? Or is one of them active? I know some subs just use the L input but I do not know about the HGS-12 and their literature is not clear. They say the L and R are summed internally so I assume that inputting an already summed signal into either L or R would be ok. Any help appreciated
