You will never be able to tell the difference but I'm sure someone out there will tell you to buy a super gizmo glitzy sub cable for $500.
You will get far more improvement in your sub by moving it around and doing some simple, inexpensive room tuning then you will ever do by replacing a perfectly good cable with an equally good cable that costs $100's of dollars.
