Input method: AUX+Bluetooth\u003cbr\u003e6. Number of channels: 2.1\u003cbr\u003e7. Channel power amplifier chip: TPA3116D2 (with AM interference suppression function)\u003cbr\u003e8. Adaptive power supply: DC12-24V\/5A or more (the higher the voltage, the greater the output power)\u003cbr\u003e9. Adapted speaker: 20~100W.4~8 ohms\u003cbr\u003e10. Output power: left and right channels 50W\/subwoofer 100W\u003cbr\u003e11. Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection\u003cbr\u003e12. Product size: 120mmx100mmx20mm\u003cbr\u003e13. Product weight: about 195 grams\u003cbr\u003e14. Tips: Only when the audio input is sufficient and the power supply voltage\/current is sufficient, there will be sufficient output power! ! ! The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power! ! ! Please ensure that the power of the adapted power supply is greater than the actual working power of the power amplifier! ! !\u003cbr\u003e15.
