Bridge -> 4700µF -> TIP122 (transistor) -> 1000µF -> A220 VCC Base of TIP122: 12V zener + 100µF to GND creative a220 circuit diagram better
Replace the main electrolytic filter capacitor with a larger value (e.g., from 2200µF to 4700µF). This acts as a reservoir, allowing the subwoofer to draw more current during heavy bass notes without the voltage dropping.
