Wiring Process
Wiring an aux cable to a speaker can seem intimidating, but it’s actually a simple process that anyone can do. Here’s a step-by-step guide on how to do it.
Splicing the Wires
The first step is to splice the wires of the aux cable and the speaker wire. Use wire strippers to remove about an inch of insulation from each wire. Then, twist the exposed wires together. If you want to ensure a secure connection, you can use pliers to tightly twist the wires together.
Connecting the Wires
Once the wires are twisted together, you need to connect them to the binding posts on the speaker. The binding posts are the metal connectors on the back of the speaker. If your speaker doesn’t have binding posts, you can connect the wires directly to the speaker terminals.
To connect the wires to the binding posts, unscrew the binding posts using a screwdriver. Then, insert the wires into the holes in the binding posts and tighten the screws to secure the wires in place.
Soldering the Connections
For a more secure connection, you can solder the wires to the binding posts. Soldering creates a permanent connection that won’t come loose over time. To solder the connections, heat up the soldering iron and apply a small amount of solder to the twisted wires. Then, touch the soldering iron to the binding post and apply more solder until the wire is securely attached to the post.
It’s important to note that if you’re working with bare wire, you should use shielding to protect the wires from interference. Shielding is a thin layer of metal that wraps around the wires to prevent interference from other electronic devices.
splicing, connecting, and soldering the wires are the three main steps to wiring an aux cable to a speaker. By following these steps, you can have your own custom speaker system up and running in no time.
Testing the Connection
