What does Pioneer mean on their speaker wiring diagrams with 2 channel mono and 2 channel stereo? I'm trying to figure out 2 channel bridged operation of a GM-A4704 and they don't specify which diagram to use for bridged operation. Also in this operation, do I wye each L and R RCA so both L inputs channels A and B have that channel's input filled?
