Learning how to run speaker cable through walls is essential for achieving a clean and professional home theater or audio setup. Exposed wires can look messy, and concealing speaker cables inside the walls helps create a clean and organized space. Additionally, it prevents potential tripping hazards and protects cables from damage.
In this guide, we will show you :
- How to safely and effectively run speaker cables through walls
- How to hide speaker cables
- How to select the right speaker cable materials

Step 1: Plan Your Speaker Cable Route
Before you start, take time to carefully plan where your speakers and amplifier will be located. Consider how long your speaker cable needs to be and whether it will need to go through multiple walls or floors. Use a speaker cable gauge chart to determine the right wire size, as using the wrong gauge can lead to signal loss or poor audio quality. The longer the distance, the thicker the speaker cable should be to maintain strong signal transmission.
If you are setting up a home theater system, think about future upgrades. Running extra cables now can save you time and effort later if you decide to add more speakers. Mark your planned cable route on the wall to visualize the path before proceeding.
Step 2: Choose the Right Speaker Cable
Not all speaker cables are the same. When selecting a speaker cable, consider factors like thickness, insulation, and shielding. Look at the speaker cable gauge vs. distance to ensure proper signal transmission. A speaker cable size chart can help you choose the correct thickness. Thicker cables (lower gauge numbers) are better for long distances, while thinner cables (higher gauge numbers) are suitable for short runs.
If you are running speaker cables for a subwoofer, you might need a subwoofer to speaker cable adapter. Additionally, check whether your cables need extra insulation, especially if they will be running near electrical wires, as interference can affect sound quality.
Step 3: Gather Your Tools
To successfully run speaker cable through walls, you will need the right tools. Here’s a checklist of essential items:
- A drill with a long bit for making holes in the wall
- Fish tape or a cable puller to guide the wire through tight spaces
- Speaker cable conduit to protect and organize cables (optional but recommended)
- Wall plates to create a professional and clean look
- A stud finder to locate wall studs and avoid drilling into them
- Electrical tape to secure cable ends and prevent fraying
Using speaker cable conduit is a great way to protect your wires, especially in areas where they might be exposed to potential damage. If you want to run speaker cable through walls without making too many holes, fish tape can be a valuable tool to help guide the wire smoothly.

Step 4: Locate Studs and Drill Holes
Before drilling, use a stud finder to avoid accidentally hitting wooden beams, electrical wires, or plumbing pipes. Identify the best spots to create openings for the cable to pass through. Once you find a clear path, drill a hole in the drywall large enough to fit your speaker wire to 3.5 mm adapter or any other necessary connectors.

If you are running speaker cables between floors, you may need to drill through multiple layers, so be prepared for a more complex process. In some cases, running speaker cable conduit can help keep things organized and prevent tangling inside the wall.
Step 5: Pull the Speaker Cable Through the Wall
Now it’s time to feed the cable through the wall. Attach your speaker wire to the fish tape and carefully pull it through the hole. If the cable gets stuck, try using speaker cable conduit to create a smoother pathway. Be patient and take your time to avoid damaging the cable insulation.

When connecting speaker cables, make sure the speaker cable positive and negative sides are properly aligned. Many cables have a speaker cable white stripe or a red and black color coding to indicate polarity. Double-check your connections to ensure the best sound quality.
Step 6: Connect and Secure the Speaker Cables
Once you have pulled the speaker wire through the wall, connect it to your speakers and amplifier. If your speaker cable is too short, you may need to extend speaker cable by using connectors or splicing the wires together. Ensure that the connections are secure and insulated properly to prevent signal loss or short circuits.

If you are using banana plugs, ensure they are firmly attached for a reliable connection. Additionally, consider using how to join speaker cables together techniques such as soldering for a more permanent and professional setup.
Step 7: Hide and Secure the Speaker Wires
If you want to keep your setup looking clean, there are several ways to hide speaker cables on wall and make them less visible. You can use:
- Cable raceways or decorative covers
- Running speaker cable through walls for a completely hidden look
- Speaker cable under carpet if running along the floor

For a seamless appearance, painting cable raceways to match your wall color can help them blend in. If you prefer not to cut into your walls, consider running cables along baseboards or behind furniture.
Step 8: Test Your System
Before sealing any holes or finalizing your installation, test your audio system to make sure everything is connected correctly. Play some music or a test tone to check for any issues. If there is no sound or the audio quality is poor, verify that the cables are properly connected and that the speaker cable polarity is correct.

Using a test speaker cable tool can help diagnose any issues. If you experience interference or noise, consider using shielded speaker cables to reduce electrical interference from nearby wires.
Some FAQs
Are solderless speaker cables as good as soldered ones?
Yes! When properly assembled, solderless connections provide excellent conductivity and durability, comparable to soldered cables. The key is ensuring a tight and secure fit.
What type of wire works best for DIY solderless speaker cables?
Oxygen-free copper (OFC) wire is highly recommended for its superior conductivity and resistance to oxidation. For main speakers, use 10AWG; for surrounds or center speakers, 14AWG works well.
How do I prevent loose connections in solderless speaker cable?
Make sure to twist the wire strands tightly before inserting them. Secure the screw firmly without over-tightening, and check for a stable fit before reassembling the connector.
Can I use banana plugs and spade lugs interchangeably?
Yes, but it depends on your speaker terminals. Banana plugs are more convenient for frequent changes, while spade lugs offer a tighter connection for more secure setups.
Conclusion
Knowing how to run speaker cable through walls allows you to maintain a clean and professional audio setup. With proper planning, the right tools, and secure connections, you can conceal speaker wires for a clutter-free space. Whether setting up a home theater or a sound system, following these steps ensures great sound quality while keeping your cables safe and organized.
By planning ahead, selecting the right materials, and using the correct techniques, you can conceal speaker cables while keeping them accessible for future upgrades. If you need to extend speaker cable or convert it for different uses, there are plenty of options available, from speaker wire to RCA cable adapters to high-quality solid core speaker cable choices.
