I see what you mean so one amp set the Audio Chanel to left and the other amp set it to right ..
So as an example
WiiM Ultra - left channel to Amp 1
WiiM Ultra - right channel to Amp 2
I presume this would work but would this would we get ‘double’ the amount of wattage per channel?
So instead of let’s say, 120w at 4ohm, would you get 240w (at 4ohm) per channel.. I suspect not ..
