If you are just finding the answer to the title, here is the place. Keep reading you can get what you want to know. As we all knows that running the audio/video cables through walls is often the best way when connecting TVs or speakers stayed in different rooms. Be a wiser man, you need to take several minutes to plan the approach before hauling out the drill. Usually, the place where holes least noticeable is often be selected. Of course, the holes should be assured to line up with each other to offer you an easy way to get the cable from one hole to the other. Cutting through drywall is really very easy even for people who have never picked up a drill yet. You only need to spent 10 or 15 minutes to finish the whole project just by having get ready for needed things such as Stud finder, Pencil, Drill and drill bits, Measuring tape, Electrical tape and Old wire coat hanger first, then following the guide below.
Step 1. Examine the wall and find a spot where you want to and are good for run the wire. That is, the place with holes and cables will be least noticeable. Usually, the place likes above the baseboard but behind a piece of furniture such as TV stand or entertainment unit will be looking the most professional.
Step 2. Find the placement for light switches, telephone jacks, power outlets and cable outlets. Often, all wires run down and up or to the side of outlets are at right angles. Thus, you should avoid drilling below or above another wire outlet to reduce the risk of damaging wires.
Step 3. Using a stud finder to find the studs behind the wall to avoid drilling through the two-by-fours running up and down or along the floor behind the drywall. Then, use a pencil to mark the place where is prepared for the entry hole.
Step 4. Measure the distance between the floor and the hole, the distance between the nearest door or adjoining wall and the hole. Then, measure the same distances from the other side of the wall, before using a pencil to mark the point for exit hole.
Step 5. Measure the diameter of the cable or the adapters on either end of the cable. Of course, you can use a ruler to do that, but a more faster way is to hold the cable against the edge of a drill bit, and then use your eyes and fingertips to determine which bit is just has the same diameter. However, you should select a drill bit which is larger than the widest point of the cable or its adapter in one or two sizes.
Step 6. Turn off the house power at the breaker box to protect you from being electrocuted while you drill through a misplaced wire accidentally.
After finished the six steps above, you can drill and feed the wire now.
Firstly, drill a hole at the entry point and holding the drill vertically, for the drill held at an angle will be difficult to get the cable through one hole into the other.
Then, drill another hole at the exit point in the same manner. And open a wire coat hanger with it straightens out, to tape the audio/video cable to the end of the wire.
Later, push the coat hanger with the cable into the entry hole and fish it through to the other side. Remove the tape from the coat hanger. Turn the power back on.
Finally, if the adapter on the end of the cable is much thicker than the cable, using a flexible caulking which matches the color of the wall closely to dress the holes.
