12) Grab your hot glue gun again and position the speakers up against the plastic grill at the
rear of the bin while you wait for it to heat up. Be sure to position the speakers on the
appropriate side of the bin.
13) When ready, tack both speakers in place with dots of hot glue. Then, run a small bead of
hot glue around the perimeter of the speakers.
14) While the glue is still hot, clean up any excess glue that may have leaked through the
plastic grill to the outside of the bin.
15) Position the electronics in the bin and fixture them in place using Velcro or a similar
method. This will prevent the components from rattling around in the bin and possibly
shorting against each other.

Optional Upgrade #1: Upgrade your battery pack
Replace your 4xAA battery holder with a portable USB power bank. Then, use a DIY USB A
connector shell (example: Adafruit 1387) to wire a male USB A plug to the power input of the
audio amplifier board instead of the AA battery pack, and simply plug the USB connector into
the power bank. Be sure to check your polarity before starting everything!
