Picture of Speaker Wires Under Baseboards
I have no attic, and no basement or crawlspace to run wires. I also don't have carpet, so I can't just stuff speaker wires under the edges. Previously, I simply stapled the wire to the baseboard, but it looked bad and toddlers like to yank them. After getting a new TV and mounting it on the wall, I decided I needed a better solution, which was running wires under the baseboards. I couldn't find any pictures or write-ups online of this, even though many people suggested it, so I figured it was time I make my first Instructable (hopefully it turns out well). 

I'm not a professional installer, carpenter, or electrician, and I did not consult any pros. I probably use some incorrect terms, and there are probably things I could have done differently, but what I did worked for me. Be sure to take all safety precautions, and use common sense, and of course don't blame me if you screw up.

Step 1: Getting Started

Picture of Getting Started
Here are the tools I used. Not pictured are a cordless drill and drill bits, a nail set, wire strippers, masking tape, putty knife, plastic scraper, and cleanup stuff. I also used some additional finishing nails (the kind with the real tiny head that has a dent for a nail set). 

Step 2: Choose Placement

Picture of Choose Placement

There are many guides online regarding best placement for sound, but I wanted it to look good since this is not dedicated theater room, so I held up speakers and asked my wife what looked best.

Mark the locations with a piece of masking tape or a pencil. You want to place your speaker jack close to the speaker, but you need to check for studs with the stud finder. I got pretty lucky, only one was close to a stud, and I only had to move it about 1/4" over to clear it. Mark your faceplate locations with the pencil in the screw holes.

Step 3: The Scary Part

Picture of The Scary Part
Removing the shoemolding and baseboards is quite possibly the most difficult and nerve-wracking part of this project. If I cracked or broke one, I'd have to buy a matching piece, cut it, and stain it, and I really didn't want to have to go through with all that. So TAKE YOUR TIME. 

Unfortunately, I didn't take any pics of the process. But I used a combination of a 4" putty knife, a plastic gasket scraper, and the chisel to gently, GENTLY pry the molding off. If your baseboards are painted, you'll probably have a harder time, since you'll have to remove caulk, and re-caulk it (and caulk and touch up paint on nail holes, if you're picky) once the project is otherwise completed.

If they don't want to come off, DO NOT FORCE IT. It will most certainly crack. Find the stubborn nail, and use a nail set to hammer it through the board, into the wall.  Label the backs of your shoe molding and baseboard, to make it easier when re-installing. 

After they're removed, this is a good time to clean all the dust off, and find whatever slipped between the boards and the walls over the years. I found a penny!

Step 4: Cutting Some Holes

Picture of Cutting Some Holes

Speaker wiring 032.jpg
This is the second most scary part, because if you screw up cutting drywall, you have to patch and paint it, and that's no fun. Using the holes you marked earlier, position the "old construction low voltage box" (I purchased at Lowes home improvement store), and mark the cut holes. These particular green boxes have 4 holes to guide you where to cut. 

Double check your positioning. Double check for studs. You'll see in the pics that I wrapped masking tape around my keyhole saw, this is to prevent me from cutting too far in, and hitting the sheetrock on the other side. Cut your hole, and save the piece you cut out, in case you need to make a patch with it later, don't accidentally drop it into the wall like I did the first time. 

Directly below this hole, you'll need to make another, that will eventually be behind the baseboard. There is a 2x4 that runs along the base of the wall, so you won't be able to cut your hole all the way down. I used the chisel and hammer to cut out the portion of the sheetrock that is in front of this board, so I could run the wires down beside the floorboards, so the baseboard wouldn't have to smush the wire against the wall.

**A note on using the keyhole saw. If you hit a wire, you will feel resistance. I didn't during this project, but have in the past. You'll probably also hear the wire banging against the wall if it's not in conduit, as you slide your saw in and out. If you elect to use a motorized tool, like a Dremel, to cut your drywall, you will not feel or hear this as easily. I highly recommend the keyhole saw.

Step 5: Tape Some Fish?

I then fixed the green box in place. Place it in the hole you cut, and it should fit if you followed your guide. If not, make adjustments with the saw. As you turn the screws, the 2 "wings" flip out and tight against the back side of the sheetrock. Don't overtighten, it's pretty flimsy.

I bought the shortest/cheapest fish tape I could find at Lowes, I forget the length, but it was plenty long enough. If you don't have a fish tape, you could probably make this work with a weight on a string or piece of small wire, provided there are no obstructions in the wall. I had one box to install on an exterior wall that was insulated, the fish tape made it easy though.

Push the fish tape down into the wall, and pull it out the bottom. I had my wife helping me, she would look for it with the flashlight and grab it with her finger. Once or twice I had to widen the hole a bit to make it easier. Attach the speaker wire to the end of the fish tape, and pull it through.

Step 6: Wiring Things Together

Attach the wire to the jack. The wire will usually have a white stripe or words on one of the wires (since it's technically a pair), I was sure to always attach the striped wire to the red terminal, just to keep things standard and not mix anything up. My jacks came with 2 screws to attach them to the box, and 2 shorter screws to attach the faceplate to the jack.

Do the same process for all 4 speakers, and for your central jack.

Run the wire in its tucked area to where it'll end up, I decided to have a central jack for the 4 surround speakers to be wired to. The front center speaker will be wired directly to the receiver. Label your wires to save some hassle, and attach them to your central jack. Attach the faceplate, label it too.

Step 7: Making it Look Nice

I used banana plugs at the receiver, because I hate working with that many screw-tight terminal thingies in that tight space. Also, this would allow me to quickly and easily remove the receiver if necessary (like to move the shelf unit for cleaning). 

Nail the baseboards back down. If you labelled them, you should know exactly where they go. Mine retained most of the original nails, so it was easy to line them up to the original nail holes. I also used finish nails to secure it a bit more. The nail set really comes in handy here, to keep you from marring and denting your boards. 

I had a few spots I couldn't run the wire in the wall. Our living room has a wood burning stove, which sits on tile, with a large tile backsplash. I used some wire mold that has an adhesive backing. The package claims it's paintable and stainable, but I just left it white. I also had to go around the door frame of a sliding glass door. There wasn't space under the door trim, and I didn't have a router handy to form a channel in the backside of the trim, so I used more wire mold here. It's not great, but I can always go back and do a better job later (when I get a router). 

Step 8: Wrap Up

Picture of Wrap Up

My speakers have a removable bracket that attaches to the wall with 2 screws. I positioned the bracket, marked the screw holes, drilled a hole, hammered in 2 anchors, and attached the bracket with the screws. Wire the speakers to your jacks, and you should have sound! 

Next up, I'd like to hide the power and HDMI cords. Luckily I have a power outlet below my TV, so I plan to cut a hole for a new outlet behind the TV, and wire it to the existing one below it. 

For the HDMI cable, I'm going to install 2 "pass through" or "recessed media box" plates, one behind the TV and one behind the receiver area. This allows me to pass a wire through the wall, so if if want to add any components later I can use it for this as well.

Great job, and very nice first instructable!
I can thoroughly recommend using fish poles rather than tape, they don't curl up on you. Much easier. Great instructable by the way.

Maybe there are different fish tapes, but this one wasn't bad. It curved just enough to keep it running along the wall.

That's pretty cool! I have a question. Can I buy a home theater control box without the speakers? My home theater system control box broke and I finished it off by taking it apart and goofing with it. Now I have the speakers and the other two speaker looking things which I don't know what they are called. Will I have to buy a whole new sound system? Any suggestions? Thanks
oakback (author)  C. Wheeler1 year ago
Yes, it's typically called a receiver. Some have limited capabilities. What I recommend is making a list of all your components that are integrated in your main entertainment room. For instance, TV, surround sound speakers, cable box, Xbox, etc. Make sure the receiver you're shopping for has the right amount and type of inputs and outputs. For me, I have a PS3 and cable box that I want to provide picture to my TV, and sound to my speakers. So my receiver has at least 2 HDMI inputs, at least 1 HDMI output, and outputs for at least 5 speakers and a subwoofer. So I end up with all the inputs going to the receiver, and 1 video output to my TV, and audio outputs to the speakers. If you have several components like me, I highly recommend the Logitech Harmony line of remotes, it simplifies control of everything and it's super easy to set up and use.
Thank you very much for taking the time to help me. I found your info very useful. Thanks again

to remove baseboard molding use a small flat pry bar found at most hardware stores. They are made specifically for this purpose. If you can afford 2 so much the better. Gently work the pry bar behind the molding and then pull it away from the wall. then work your way along the baseboard, gently wiggling the pry bar and pulling the board away from the wall.
BTW this is a great idea! great 'ible
oakback (author)  urwatuis4 years ago
I have one, but didn't use it, because of the slim width. Any time in the past that I've tried using a flat pry bar, if the board was tight at all, I'd end up denting the sheetrock, or marring the board. I'm sure it would have been very useful to have 2 and use them that way, but the 5"-wide non-flexible putty knife worked great. It spread out the prying force, so I wouldn't dent the sheet rock.

What would be great is a tool with the angle a flat pry, but with a much wider pry tip.
I'm glad I took a peek at your instructable - I've used those green low-voltage, old construction brackets before, and never noticed that they had 4 marking holes. Thanks!
oakback (author)  markstutzman4 years ago
Glad I could help! I just happened to notice on the edge of the bracket, it says something like "mark here for cut guide" with arrows pointing toward the holes. I make it a habit of inspecting things when I'm working with something new (this was my first time installing brackets, and using the fish tape, and cutting holes in my walls).
I love your work, beautifully done! ....and I was just thinking towards the end why hasn't he hidden the HDMI and power cord, could have fed them through the wall at least to the baseboard until you were ready to finish it.......but I then read on to see that you had thought about and are going to do it. Hopefully you will also create a channel under the door, which you have also mentioned... great job! No room for comments!

Thanks! I'll definitely post an update when I finish the rest.
