Filter for rpi jack audio and rpi0 pwm audio out. Clean audio before the amplifier input. Low pass filter, step down tension from 3.3V to 1.1V and 10uF capacitor to protect speaker from CC.

I would assume rpi has 3.3 VDC output, not AC. The equivalent AC output would be 1.17 VAC RMS, 1.65 VAC peak, or 3.3 VAC peak-to-peak.
