I don't think this amp can do bridged mono.
The back diagram is very confusing, and it doesn't look the same as the previous Inuke and ep4000 versions.
I basically wired +1 and +2 like I did for my EP4000, channels A and C, B and D seem to be bridgeable. I bridged B+D by flipping the switch to bridge, inserted the speakon into output B, and I get no sub sound. Crossovers are on full range.
I could just unscrew my sub and rewire the inside as +1 -1 +2 -2, but I'd really rather not have to do that. Any ideas?
Crap, I can't do that. I have D4 specifically to bridge it. Not sure I'd want to go 2 ohm into 2 channels.
