Power and power:The power amplifier adopts TPA3116 chip, the actual output power can reach 50W per channel, 2 channels total 100W (24V power supply), equipped with 12V5A power supply. The output power is 30W*2 (4 ohms), if connected to 8 ohms.
The output is about 15W*2. If you need more power, you can configure the power supply yourself. Be careful not to exceed 24V. Otherwise, the chip will be burned out and the power supply should not be too small, because power = voltage * current, if the current power is less than 50W. There may be a power outage.
Amplifier output:The power amplifier is a fixed-resistance power amplifier. It supports 4/6/8/16-ohm passive audio/horn. It can't be connected to computer audio and other active audio. It is not suitable for passive subwoofer. The 4 pillars behind the power amplifier are output interfaces. 3.5mm and other earphone plugs or lotus plugs
Car modification:Conventional car and motorcycle 12V batteries can be directly modified and supplied.
Large 24V batteries such as large trucks are not recommended because the voltage will exceed 24V after starting the car. Unless the voltage is reduced by other devices, the power amplifier will be too hot. Long-term use is not good for the chip, even burned out. If you want to modify to the car or use battery power, etc. must be limited to DC24V 5A, the power amplifier plug size is 5.5 x 2.5MM or 5.5 x 2.1MM
