Again plan how you want to run your cable.
Cost to run speaker wire through ceiling attic.
I recently bought 200ft of 16 gauge speaker wire.
Running surround sound wires using crown moulding.
Hole down through the top plate.
Attach the cables and pull them up into the attic.
Fish cables through existing walls with fish tape or a fish stick.
Terminate the cables in low voltage electrical boxes.
Joysts seem to run with air vents transversing the space but if they are open then figure on 3 4 good size holes and 3 days added to the original work to float texture and paint.
And use semi rigid.
Just found through a friend of mine that the speaker wires need to be shielded if i plan to run them through attic and also i need a permit.
Running audio video cables behind walls is similar to running electrical cables but a v cables should be at least a foot away from electrical cables to prevent interference.
Depending on what the wiring is for this may be go through the drywall to the ceiling for instance for new lighting or be farther down on a wall.
You will tuck the cabling above this piece of wood and it will also.
Poke a reference wire through the ceiling then in the attic find the wire and measure over to find the center of the wall.
I plan to run speaker wires for my ht through the attic.
Cut the holes that the wire will pass through to enter and exit the attic.
Pull the wires through the walls.
If you will need to fish wiring through a wall drill a hole through the wood plate in the attic only.
Drop a weighted string through the hole.
Depending on what direction your joysts run and whether there is open web trussing when you stick a stud finder on the ceiling i would do anywhere from 500 1200.
