Product Introduction:
This product uses a brand new original IC chip with overvoltage protection, overcurrent protection, overheating protection, and short circuit protection.
The input voltage is 12-24V, and the output power is 50W * 2 (50W * 2 when the input voltage is 24V, and 25W * 2 when the input voltage is 12V). The volume can be adjusted by turning the knob to the right to increase the volume, and to the left to decrease the volume until the power amplifier board is turned off. High definition BT 5.0 or AUX port audio input, dual channel output.
