Hello. I have a question on getting the most sound out of my sub. I chose to position the sub near the back of the room where the seating is located because I love the rumble on the sofa when those lows hit.

My question is this. I just receintly moved my equipment around and have about 25 feet of cable run from my equipment to the sub. Is there a big benefit to get a dedicated cable for the sub (one like the Monster Sub 300 cable) A 24 foot run will cost around $75.00. Will I notice a big difference between that cable and a regular audio cable?

Part two to my queston is this... My receiver has one output for the sub and my sub has a right/left input. One person said to simply connect one cable to either the right or left on the sub, and another said to run both and split them out at the receiver. I do notice a small difference in less out put if I only run one wire. But not sure if the better cable will make up for this. Any suggestions?

AD, to answer you in reverse order:

Inputs like the one your sub has are known as 'summing', meaning the signals add together. 99% of the time, there is a resistor in series with each input that are tied together toward the amplifier. Using a Y-cord effectively parallels the two resistor, which halves the resistance. A small adjustment of the input level control would have the same effect, so, no, you don't have to use both jacks.

Whether a brand name cable makes an audible difference has been a subject of debate for decades. If the answer were clear, there would be no debate, so the best thing to do is try for yourself. My personal opinion is that a good-quality cable is adequate. I wouldn't pay $75 for a 24ft. cable, unless I were a millionaire, and even then, maybe. If I were doing a home theater install FOR a millionaire, on the other hand, I might suggest it.
