Richingoth,
Thank you for the advice. I'll try that. However, I have few questions for you before I try your suggestion. Since the subs are split from a Y connector in the back of the Yamaha, it will be tight and difficult for me to plug and unplug one another, assuming that I'll be content with one shot. Will it be all right if I keep the Y splitter on, just turn off one sub and leave the other sub on to calibrate, and do it vice versa. The mono signal split by the Y connector into dual subs should remain the same if I proceed with your method, correct? Again, thank you for all your help. You can tell by now that EE was not my major in college. :> )
