Becareful, you might be mixing up two different concepts here. The Center channel has one phyical cable with two cable strands inside: + and - (or black and red). But there isn't a LEFT center channel and a RIGHT center channel.


The Sub typicall uses one physical RCA terminated cable. If you have two subs, you need a Y splitter or subs that know how to daisy chain.
