Okay.. this is a stupid question, but one I've been wondering for a while.. I have a Velodyne VA-1215X for a very long time. My Velodyne has 2 RCA inputs for Line In.. I have one output for the Subwoofer from my Denon 3805 receiver. Do I run a single RCA cable from my receiver to a RCA splitter into the 2 RCA ports of the Subwoofer? Or do I just hook up one, or run dual RCA cable to the sub (splitter would be at the output of the Receiver). Or does it matter? Thanks for the answer.
