NOTE:
Please note that this product does not include a power supply, you need to equip it with a DC power supply.

Tip:
To have enough output power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound power. Please ensure that the power of the adaptor is greater than the actual working power of the amplifier.

It is recommended to use a DC power supply within 20V. If you use a battery pack to supply power, make sure that the battery voltage is lower than the rated voltage when the battery is fully charged.
