Low-cost Spherical Speaker Array

Step 14 Solder the wires to the terminals

For each speaker wire, cut some short lengths of heat shrink tubing, and thread it on to the ends of the wire. Solder the wire to a pair of terminals, making sure to solder the positive wire (red, striped, etc.) to the positive (red) terminal. After the joints cool, slide the tubing over them and use your "heat gun" to shrink the tubing.
