Is adding an additional EP500 Sub as easy as adding a male to dual female RCA splitter out of the back of the receiver to add a second sub? How does that effect the MCACC (Pioneer Sc-27) calibration when the receiver only sees one subwoofer? and cannot differentiate on the distances that it sets the sub and speaker levels ect? People have told me I can just add the spitter but this made me think about the calculations the receiver makes on the speakers.
