Behringer A800 Bridged Mono Mode setup

Hi There


I am fairly new to the entire topic. I bought two Behringer A800 Amplifier with the idea in mind to power my two passive speakers. One I thought to use for the left and another one for the right speaker. My Question now is: How can I set up the A800 in bridged mono mode? Do I simply use Output A, leave Output B empty and use input A for either right or left? I am aware of the bridge mono switch. 


I am also a bit stuck on the cables as I read that I have to switch one end of the speakon cable from 1+ to 2+ and 1- to 2-. Sadly I can find nothing on this in the instructions manual.


I am thankful for any input that might help.


Cheers!
