..I used an external 5 ch amp to run my speakers and use the receivers speaker-level outputs for the L/R surround speakers to drive additional surrounds. I have a Denon 3801 and this way I'll have four surrounds (2L and 2R) and two rear surrounds making a total of 6 surround speakers. Do you think it would work? Furthermore, if it works what if I used the unused receiver L/R surround outputs and hooked two surround speakers out of phase with the surround channels driven by the separate amp (ofcourse facing away from each other) so I have dipolar effect in the surround speakers with two identical direct radiating speakers. Am I making sense or is this all gibberish?
