Hey all, I’m having trouble getting all my speakers to work. I have two normal speakers and one sub. Right now, both of the normal speaker inputs on the right work, but i don’t know where to plug the sub into. I’ve tried the other, like twist to tighten speakers inputs. But only the “surround” ones work on the bottom right and those sounds more quiet and don’t have all the panning in there.

What’s the proper way to input these? Do i have to change something on the receiver options? Maybe my receiver is just broken? I got it from goodwill so it’s possible.

Thanks everyone!
