I am a newbie and just bought a used Polk RM3000 (2 surrounds and an unpowered sub-woofer.
There are 5 connections on the back of the sub. Left channel in (red and blck connectors), right channel in (red and black connectors) and a center connector which is blue and has no markings.
Does this sub-woof connect to the surrounds???
Any helpl would be appreciated.
