Building small guitar practice amp. Available junk box parts include
several 4" 3.2 ohm speakers culled from a 1984 vintage cassette
boom box. Since the schemos I've seen all call for 8 ohm speakers,
should I expect these speakers to sound like crap, or will they
likely
sound okay?

The main problem would be the possibility of the LM386 overheating and
dieing.

You could put two speakers in series to get 6.4 ohm which would be somewhat
better.

You should also increase the output coupling capacitor to match the reduced
impedance of the loudspeaker if you want to keep the bass response the same
as in the design intended for an 8 ohm speaker.
