S300 Powering Center Channel

I’d like to run my Stellar S300 as a monoblock to run my Martin Logan Motion 50 XT.
I’ve seen some videos, but I need some stupid simple directions.
Example: plug the red in the black on the right channel etc

Thank you in advance,

So are you trying to just use one side of the S300 to power the center? Meaning you won’t be using the other channel on the amp?

I’d like to use it In bridge mode
I’m currently using just the one channel
