This step requires soldering. Soldering can cause injuries such as burns to the skin. It can also produce fumes that are harmful so working in a well-ventilated area is advised.

Use wire strippers to remove about 6 mm of insulation from the detached speaker wire.

Set the soldering iron to 350 degrees.

Add solder to the tip of the iron and then touch the tip to exposed wire.

Join the wire with the electrical contact on the speaker.
