NOTE: The wires must not be tinned: tinned wire does not hold tight in the
captive screws and can break easily after several bends.

3 (Bridge B) only. Bridging effectively doubles the output power of those
inputs. Inputs 1 and 3 are the active inputs when in bridged mode while
inputs 2 and 4 are ignored (see the diagram below).
