. This is a DIY speaker kit from DeGraw (amzn.to/3eBCPMY) for projects like Arduino/Raspberry Pi or others (here I'm looking at it as a potential stereo speaker install for a 5.25 drive bay enclosure in a computer). Here I unbox, assemble and test the system on the bench. It comes with two 3 watt 8 ohm speakers (bare wires), a stereo 3.5mm audio connector (bare wires), a five-volt amplifier controller and a set of 2.54mm DuPont header pins.
I decide to solder on right-angle DuPont male header pins for the amplifier's inputs/outputs and crimp-on female connectors for the 3.5mm audio cable and speakers (and you'll see these connectors are not the most fun working with).
When everything is connected up and all parts have good connections the amplifier and speakers work pretty well. Initially I had issues with the crimp-on connectors not providing good conductivity and also had the L-R connections on the audio input reversed. I've since put the speakers and 3.5mm cable into 4-pin and 3-pin housings respectively instead on individual ones.
