Replacing old, worn out speaker wire in your backyard can seem like a daunting task, but with the right tools and a bit of know-how, it's actually quite straightforward. In this comprehensive guide, I'll walk you through the entire process step-by-step.
Gather the Necessary Materials
Before getting started, you'll need to gather a few key items:
-
New speaker wire - Make sure to get wire that is designed for outdoor use. Oxygen-free copper (OFC) or copper-clad aluminum (CCA) wire are good options, as they resist corrosion. The gauge (thickness) you need will depend on the length of your wire run. For runs less than 50 feet, 16 or 14 gauge is usually sufficient. For longer runs, you may need 12 or even 10 gauge wire.
-
Wire stripper - A basic wire stripper with both small and large gauges is ideal. This allows you to cleanly remove the insulation from the wire.
-
Crimp connectors or solder - To connect the new wire to the speakers, you'll need crimp connectors and a crimping tool, or a soldering iron and solder.
-
Conduit or burial-rated wire - For running the new wire underground between speakers, use PVC conduit or wire that is rated for direct burial.
-
Mattock and shovel - Useful for digging a trench to bury the new wire.
Disconnect and Remove the Old Wire
Before installing the new speaker wire, the old wire needs to come out. Here are the steps:
-
Unplug receivers and amplifiers - Shut off all power to your audio equipment before disconnecting anything. Safety first!
-
Label connections - Use small pieces of tape to label each end of the old wire so you know where it connected. This makes re-installation easier.
-
Disconnect old wire - One at a time, pull the wire ends out of the terminals on the speakers and receiver. Coil up the wire as you go.
-
Remove wire fasteners - If the old wire is stapled or fastened to walls/ceilings, carefully remove any fasteners.
-
Pull out old wire runs - Slowly pull the old wire through any conduits or buried trenches as you coil it up. Be sure not to leave any wire behind.
Properly removing the old wire is crucial - don't skip this step!
Run the New Speaker Wire
Now the fun part - running the new wire. Here's how to do it right:
-
Plan your wire runs - Think through how you want to route the new wire and draw yourself a simple map if needed. Determine if you can reuse old runs/conduits or need new ones.
-
Use conduit if re-using old runs - For existing runs, pull out the old wire and use it to help slide new conduit in place to protect the new wire.
-
Dig new trenches as needed - If making new buried runs between speakers, use a mattock and shovel to dig a trench at least 6-10 inches deep.
-
Lay wire in trenches - Unroll the new wire through the trench, leaving a few extra feet at both ends. Avoid sharp bends.
-
Bury wire - Once laid out, carefully fill in the trenches while leaving the ends exposed. Mound extra dirt over buried portions.
-
Run wire through walls/ceilings - For indoor runs to speakers, fish the new wire through holes, conduits, etc. Use fasteners to secure.
The goal is to safely route the new wire from your receiver to each speaker location. Take your time here.
Connect the New Speaker Wire
You're in the home stretch now. Just need to securely connect the new wire:
-
Cut wire ends cleanly - Use your wire stripper to cut both ends of the wire cleanly and remove about 1/2 inch of insulation.
-
Attach connectors or solder - If using crimp connectors, attach them now using your crimping tool. For solder, heat up the exposed wire and dab on solder.
-
Connect to speakers - Match the wire labels you made earlier, and connect each end to the correct speaker terminal. Follow polarity (+ to +, - to -).
-
Connect to receiver - In the same manner, connect the other end of each wire run to the correct receiver/amplifier terminal.
-
Secure connections - Once connected at both ends, gently pull on the wires to ensure the connections are tight and secure.
Double check all connections before powering your system back on. Now you can crank up the music!
