CECAA850 Posted October 26, 2009 Share Posted October 26, 2009 One RCA "sub out" at the receiver connected to one RCA "sub in" on the sub. Quote Link to comment Share on other sites More sharing options...
Moderators Youthman Posted October 26, 2009 Moderators Share Posted October 26, 2009 Yeah, there are two ways to hook up a powered sub. 1. RCA (as mentioned). Sometimes you need to get a "Y" adapter since the sub cable will be a single RCA out from your receiver and on the back of your sub, you probably have a Left and a Right RCA input. 2. Line Level Inputs (speaker wire). You would need to run two speaker wires from the Left and Right channel of your receiver to the line level inputs to your sub, then two other speaker wires from the line level output on the sub to your main speakers. Unfortunately, either way in your case, you will need to re-run wires. I would go with the first option. Quote Link to comment Share on other sites More sharing options...
