Combining two separate sound systems to one PC

[Enochian]

Hi , 

I have a 2.1 setup from Edifier.  THe two speakers connects to the sub, from it green jack goes to rear of my strix 370-e mobo. I connect this to Line out. 

 

 

I would like to buy a 2.0 speakers system to put behind me.  Something like https://www.x-kom.pl/p/310127-glosniki-komputerowe-edifier-20-r1600tiii.html

 

 

Would this setup work ? Can i connect the 2.0 to the black REAR mobo outlet?

If the purpose is to get surround sound, I think it should work as a 4.1 setup, yes

Yup just have to connect them to the correct ports then and set it up correctly in the driver. However using many different speakers for a surround setup can cause some weird sound interactions as well they will not have the same sound profile and you can hear things in the wrong way. It can also work totally fine really just depends on the speakers in action.
