ASSEMBLY INSTRUCTIONS

We will begin by installing the speaker. Be careful to properly mount and solder all components. Diodes and
electrolytic capacitors are polarized, be sure to follow the instructions carefully so that they are not mounted
backwards. Check the box when you have completed each installation.

Cut two 1 1/2” wires and one 1” wire and strip 1/4” of insulation off
of both ends. Solder the wires in the locations shown.
