Important Notes
- The 18W rating refers to the amplifier IC's capability under specified test conditions and does not guarantee 18W output from this 6V–12V module.
- Actual output power depends on supply voltage, speaker impedance, circuit configuration, and cooling.
- Use a regulated DC power supply with adequate current capacity.
- Check speaker impedance compatibility before connecting.
- Avoid short-circuiting the speaker output.
- The heatsink may become hot during operation.
- Do not connect the speaker output directly to a microcontroller GPIO pin.
- This is a mono amplifier, not a stereo amplifier.
- Confirm the module's input and output polarity before applying power.
