To power the amplifier, we'll need to cut the female end of the JST extension cable and solder it to the VDD and GND pin. To make powering efficient, we'll create a slide switch adapter to make the lithium polymer battery turn off and on with the slide switch using another JST extension cable.
Use a JST extension cable to create a slide switch adapter. The positive cable will split a connection to the two terminals of the slide switch. You will need to shorten the length of the JST extensions as short as possible. To avoid soldering the JST extension that is connected to the switch, use another JST extension to solder into VDD and GND pins.
Use a wire stripper to expose a small piece of each wire at the end of the cable. The white wire needs to be soldered to the L+ pin. The red wire will connect to the R+ pin. The black wire connects to the L- pin. You will need to jump the R- and L- pins with a separate wire.
A male jumper wire soldered to each channel allows you to quickly connect and disconnect the speakers. Female jumper cables will need to be soldered to the left+ and right+ pins on the TPA2016. Each channel will need a red and black wire soldered to the pin.
Modify SpeakersSnip off the connector at the end of the speaker set. Use a wire stripper to exposure each wire. Tin the exposed wires to make the connections easier. Solder the male jumper cables to each of the speaker wires. Use a piece of shrink tubing to secure the soldered connections.
