Modifying an old amplifier/speaker for a separate input using wire clips instead of a stereo jack.
Step 1: Disassembly
Here we have the base audio amp and speakers from the bottom of an old Dell CRT. We're going to add an additional input to this so that we can push through sound from our MCU projects and other things that a stereo jack is too cumbersome for.
You have to remove the two back feet to access the last two screws and get the cover off.
