Outdoor Speaker Wiring Guide: How To Plan & Cable Outdoor Speakers

Installing outdoor speakers can significantly enhance your outdoor entertainment space, whether you’re hosting gatherings, parties, or simply enjoying some relaxation time. However, setting up outdoor speakers requires careful consideration, especially when it comes to wiring. In this simple guide, we’ll delve into the intricacies of outdoor speaker cabling, providing essential tips to ensure a seamless audio experience in your outdoor oasis.

Planning Your Speaker Layout

Amplifier Location

Choosing the optimal location for your amp for outdoor speakers is crucial for seamless outdoor speaker installation. Consider installing the amplifier indoors, in a dry environment such as a garage or garden room, ensuring easy access and protection from the elements.

Speaker Placement

Strategically plan the placement of each speaker to achieve balanced sound coverage across your outdoor area. Position the speakers within a reasonable distance from the amp for outdoor speakers to minimize cable lengths and optimize performance.


Wiring Route

Identify the shortest and tidiest route for wiring between the amp for outdoor speakers and speakers, considering factors such as cable lengths, obstructions, and weather protection. Conceal the cables wherever possible, ensuring they are securely installed to prevent damage and maintain a neat appearance. Be sure to install the amp for outdoor speakers in a dry place to keep the wire connections in optimal conditions.

Choosing the Right Outdoor Speaker Cable


Selecting the appropriate gauge for your outdoor speaker cable is crucial for optimal performance. Thicker wires, such as 16 or 14-gauge, are recommended for long distances and high-power applications commonly found in residential outdoor speaker setups and amp for outdoor speakers.

Direct Burial or In-Wall Rated

Ensure that your outdoor speaker cables are rated for outdoor use and capable of withstanding exposure to moisture, UV rays, and temperature fluctuations. Look for cables labeled as “direct burial” or “in-wall rated” to ensure durability and longevity.

Copper vs. Copper-Clad Aluminium

Opt for copper wire due to its superior conductivity and corrosion resistance compared to copper-clad aluminum wires. Investing in high-quality, full copper cables with UV protection, such as QED outdoor speaker cables, ensures reliable performance and longevity for your outdoor audio system.

Installing The Cables

Measure & Cut The Cables

Accurately measure and cut the cables to the required lengths, leaving some extra slack for flexibility during installation. Ensure precise measurements to avoid any issues during the installation process.

Run The Cables

Route the cables along the predetermined path, securing them to walls, fences, or other structures using clips or fasteners. Take care to avoid running the cables near electrical cables or potential sources of interference.

Protect The Cables

Protect the cables from physical damage, UV exposure, and moisture ingress by using conduit or conduit sleeves when running cables along fences or buildings. Bury the cables underground or conceal them within landscaping features whenever possible.

Connect The Cables

Strip the insulation from each cable end and connect the positive (+) and negative (-) terminals of the speakers to the corresponding terminals on the amp for outdoor speakers. Ensure secure connections to prevent any issues with sound quality or performance.

Testing & Troubleshooting

Once the installation is complete, it’s time to test the system and ensure everything is working correctly. Play your favorite music and verify that both speakers are functioning as expected. Troubleshoot any issues, such as distortion or connectivity issues, to ensure optimal performance.

Proper planning and installation of outdoor speaker wiring are essential for a seamless and enjoyable audio experience in your outdoor space. By following these guidelines and investing in high-quality cables, you can create a captivating outdoor entertainment area that will impress your guests and enhance your outdoor lifestyle.
