Wires for Audio Amplifier
The PAM8302 will need four wired connections. Three longer wires and one shorter wire. These wires will connect to the amplifier to the CPX. The potentiometer will be wired inline with the amp and CPX to allow volume adjustment.
Using wire strippers, remove a bit of insulation from the tips of each wire. Then, tin the strands of wire together using a bit of solder. Third helping hands can help keep the wires in place while applying solder. Heat shrink tubbing will help keep the wires together.
Amplifier Wires Soldered
Solder the wires to the pins on the PAM8302. The shorter wire should be wired to the A– labeled pin.
