Please help, I am retarded. I am attempting to reproduce a speaker amplifier but on a much smaller breadboard, for a personal project. Circuit diagram is in link.
http://afrotechmods.com/tutorials/2017/01/17/how-to-make-a-simple-1-watt-audio-amplifier-lm386-based/

I have everything wired up, but nothing seems to happen. When I hook up a phone or mp3 player to the circuit, nothing but silence. Nothing is overheating either, though. It's evident that I either have the wrong parts or have wired something up wrong. I have never done something like this before, and though I have a light understanding of how to wire stuff up, I'm a bit lost. Can anyone point out any errors that I may have performed, or if I used the wrong parts? I followed convention when soldering the speaker wires in, with red as positive and black as negative.
