Special attention 1

1) Working voltage:

Red 2p socket 12V: DC 7V to 12V, not higher than 12V;

If the current is not enough, there will be abnormal jumping, remote control failure or BT reading failure (if there is such a problem, please check the power supply); the voltage should not be higher than the highest value of the voltage range required by the product; otherwise, the main chip and related components will be damaged.

2) The power ground and signal ground of the module are separated, and there is a separate resistance, which is more convenient for the selection and use of different power amplifiers (see the 0 resistance of R21 on the board). Now it has been shipped to a 0 connection. Some power amplifiers are noisy. It is recommended to use a separate power supply to supply power to the board. If the power supply is connected in parallel with the power amplifier, disconnect the 0 resistance of R32 connected between the audio output ground of the board and the power supply ground before wiring (operate in case of power failure). If you don't understand the wiring or other probl, or can't handle them correctly, you can contact us at any time.)

In order to e the product work normally, independent power supply is recommended for the module

Precautions for vehicle modification

Power supply: the power supply cannot be directly connected to the battery, arette and door lock. These three voltage instability, there are precedents of damage to the circuit board. In addition, some cars also have interference. look out!!
