How to Fix Speaker Wire

Speaker wire can operate poorly for a variety of reasons ranging from degradation of the wire casing along the length of the wire, which can cause wire wear and fraying, to fraying at the end of the wire which causes a poor connection, leading to bad sound. With a little skill with a soldering iron, you can use wire solder to repair a frayed wire or bad connection, and electrical tape to re-cover an exposed wire.

Step

Strip any remaining plastic casing that encroaches on the area of the wire that you will be working with.

Step

If you are repairing or reconnecting wires, and the wires are not still twisted together, begin with the wires at a 180 degree angle to each other (like this: ), then twist the frayed areas of the wire together until they look like a candy cane.

Step

Secure the wire you wish to repair in a third hand mechanism, which will hold the wire still while you work the soldering iron.

Step

Apply the solder to the exposed areas of twisted wire. You may need to touch the solder on the wire with the iron to finish melting it.

Step

Allow the wire to cool to room temperature.

Step

Carefully wrap electrical tape to cover the exposed areas you just soldered. If your wire is losing its protective covering, you can also use electrical tape to repair the damage.
