My receiver has two subwoofer output connectors (I guess to hookup two subwoofers if you have them - I don't). My subwoofer has two signal input connectors. Today I have one of the receiver connectors connected via good quality RCA cable to a splitter at the end going into both sub input connectors. I think I heard somewhere that this was the way to go. Any reason why I should not do what I'm doing or maybe send both outputs to both inputs? Thanks!
