Quick question if anyone has experience with this. I am routing my rear surround sound speakers and the sub thru the wall. I have made some custome wall plates to accept the speaker wiring and the sub RCA cable. What I wasnt expecting was the in-wall side of the sub RCA connector to not be an RCA connection. It appears to be a crimp on type connector or I could just solder (sp?) a wire to it. Anyone know what type of wire to use with this? Can I just strip the RCA cable I had planned to run thru the wall and solder it?
