Solder one end in the upper motor terminal.

You’ll solder in 10 places for each motor POT:
3 terminals for the right channel
3 terminals for the left channel
Motor+ wire
Motor- wire
2 mounting terminals near the center of the motor POT footprint.
Make sure that the motor wires don’t touch the metal back
Perform the following 4 steps to avoid losing the nuts that will be used to attach the
volume, balance, bass and treble controls to the front panel. (On some kits, you may find
that this hardware is already in place on the ends of the pot shafts).
Pot 1 shaft Slip larger diameter washer over the shaft. Loosely
spin on a larger diameter nut.
Pot 2 shaft Slip larger diameter washer over the shaft. Loosely
spin on a larger diameter nut.
Pot 3 shaft Slip smaller diameter washer over the shaft. Loosely
spin on a smaller diameter nut.
Pot 4 shaft Slip smaller diameter washer over the shaft. Loosely
