it will be fantastically unhappy about a 4? speaker. The LM386 is designed for an 8? minimal speaker. The "Amplifier with 50 earnings" is a extra acceptable wager than the first minumum element one as not one of the inputs are floating. Floating inputs can p.c.. up all kinds of garbage and would reason the LM386 to oscillate and shrink (nicely annihilate) amplification. will be nicely worth putting a 1000pf (1nf) cap between pin 3 and floor in case you'll use a 50K? truly than a 10K? pot as cautioned.
