So to start off i have a Asus ROG strix z-390 e - gaming motherboard and i have a monoprice ssw-12 12" sub and my normal speakers are logitech z313 speaker/bass pair. So my main problem is that i cant get them to work at the same time. I dont know if i even can but i dont know how to go about trying to get them to work at the same time. I have the sub plugged into the c/sub port and the speakers into the green line out port. If someone has any idea how to get them to work it would be much appreciated!
