Hey all
New to the group here and looking for some help please. I

recently bought
a house, the individual who had it built ran speaker wires

all through out
the house behind the walls and in the ceiling while it was

being built....
( cool I like this) It all comes from a distribution panel

(similar to this
The speaker side of the wires are
just hanging wires. I would like to connect them to a wall

plate for a
neater look ( simple enough right...)
Now on to my question ( thanks for your patients) the wire

he chose to
use is a solid color the insulation is brown and the wire is

twisted copper
no distinguishing marks for + or - Is there a way to figure

this out? Should
the + side have any amount of voltage. The wires closest to

the distro box I
can ohm out and figure those out.. the ones on the other

side of the house
and outside im stumped.... any suggestions?
