I fished my both my rear speaker wires through the drywall. It looks great.
When there is no vapor barrier, the fishing was fairly simple, just needed patience. However, when i encountered a vapor barrier, it was all but impossible to fish. So, I had decided to use the adjacent wall, which doesn't have a vapor barrier. It worked, just like the first rear speaker wire.
However, here is my concern, how do i fish speaker wire that may have a vapor barrier behind the drywall. I have two more speaker wires to fish, but i am guessing there is a vapor barrier, as the drywall is an exterior wall.
Anyone have any experience with fishing through a vapor barrier?
