I use a 2 channel amp for the rear surrounds. It is located near the right rear surround speaker and has a moderately long interconnnect to my Outlaw Audio ICBM. This amp has a short run of speaker wire to the right rear speaker and a longer run to the left rear speaker, but beings the speaker wire is 10 gauge, I am not concerned.
