I built a Game Boy Macro but I didn't like any of the solutions for wiring in a speaker so I decided to go with just using some earbuds. Then I thought, why not just painstakingly design and build a tiny speaker that can connect directly to the Game Boy? So off I went to source some parts for my build and set out to design the coolest, littlest speaker.
Alas, tragedy struck! I should have KNOWN the 3.5mm jack just doesn't provide enough power to drive the speakers I chose. Even at max volume you have to hold the speakers 4 inches from your face to hear anything! So why did I upload this build? SO YOU TWO CAN SHARE IN MY SHAME! IDK maybe someone will find a solution and build off my work. At least it LOOKS cool.

You'll want to wire the speakers according to the wiring diagram I have uploaded. These wires are so tiny and a pain to work with, so I recommend replacing them with some slightly larger wires. Once you are wired up you'll want to glue the 3.5mm jack in place to keep it from moving around. Pro-tip: Label your speakers so you know which side is which. Place the speakers into their respective grills, using the sticky tape they come with to hold them in place. Carefully assemble the speaker taking care to not pinch any of the wires. It should be a tight fit that should audibly snap together. Use some m2 screws to hold the pieces together then just throw the whole thing into the trash because you ain't gonna hear a gosh darn thing.
