Subwoofer impedance: 2-8 ohm
1. Output power and power supply voltage, speaker impedance, and audio source input size. Usually the power supply voltage is higher and the supported output power will be larger.
2. Speakers with different impedances can support different output powers. Usually, the power of the speakers is smaller and easier to achieve.
Wiring method (important):
 Instructions for checking the web page before use >> 2. Connect the speaker cable >> 3. Connect the audio input cable >> 4. Confirm the wiring is correct, and finally plug in the power!
