I have 4 LaScalas and just acquired a klipsch sw-15 sub that i was wanting to hook up with these. I am currently using a 2 channel Adcom GFA-5400 amp and a Adcom GTP-500 Pre Amp. I have the LaScalas stacked, and wanting to add this in. What would be the correct way for hooking this sub into this configuration, as far as how the speaker wires would be. Thanks.
