Anyone here tried turning a 6.1 setup into a pseudo 7.1 setup by wiring 2 back surrounds in series? My receiver is only a 6.1 (only powers 1 back surround output). Seeing that I have 2 speakers available for the back surrounds (so why waste 1 speaker), I am thinking of wiring the 2 in series at the back of my room. They will both be outputing the same signal, but perhaps having 2 at the back might improve the 360deg sound imaging (maybe not?).

Anyone tried it?
