I have a DIY Tempest sub with the PE Plate amp and a HK 520 reciever. I just went to Best Buy to buy a sub cable and they had 2 cables, a Monster which clearly showed 1 output from the reciever to Right and Left to go into the sub. They also had an Acoustic Research cable for $10 cheaper which didn't clearly show the connections, but I figured it would be the same. Well, turns out the AR cable is just 1 input and 1 output, so what I need to know is if it matters or not. I know sub's are mono, so I'm thinking i could just plug it into the sub in either the right or left channel and it should work right? Is there anything wrong with doing this or should I go get the Monster cable that plugged into both R and L inputs?
