I was wondering. My M&K Sub has a left/mono and right LFE connection. I purchased a Diamondback subwoofer cable from audioquest and it comes with an adapter to hook up both right and left outputs on subwoofer to the one subwoofer channel on my Marantz SR8200. Is this good to do or is one of them enough. Also if it is better to hookup only one should I hook it up to the one that corresponds to where my speaker is, my sub is on the right so it should be connected to the right output of the sub? Thanks.
