Power and power:

• The power amplifier adopts TPA3116 chip actual output power can reach 50W per channel total 100W with 24V power supply
• Equipped with 12V5A power supply
• Output power is 30W*2 with 4 ohms if connected to 8 ohms the output is about 15W*2
• If more power is needed the power supply can be configured but should not exceed 24V
• Exceeding 24V may burn out the chip
• Power supply should not be too small as power equals voltage multiplied by current
• If current power is less than 50W there may be a power outage

Car modification:

• Conventional car and motorcycle 12V batteries can be directly modified and supplied
• Large 24V batteries such as large trucks are not recommended
• The voltage may exceed 24V after starting the car unless reduced by other devices
• Long-term use may overheat the power amplifier and damage the chip
• If modifying to a car or using battery power must be limited to DC24V 5A
