Hey ya'll! So I have this old system that I've set up in my shed just to have something in there while I work, but I happen to be a bit of an audiophile at the same time so it's kinda bothering me that I can't seem to get the rear speakers to work on this system. I've read the manual and there doesn't seem to be anything about any particular settings other than just plugging them into their respective outs. I'm not sure what I'm missing if I'm missing anything at all. I checked the connection by plugging them into the right and left so I know they work. If, there's anyone who has this or a similar system that might have any insight, it'd be greatly appreciated.
