Connect the speaker cable &gt;&gt; 2. Connect the audio input cable &gt;&gt; 3. Make sure the wiring is correct, and finally plug in the power!<br /> If you need to change the wiring or move the circuit board, you must disconnect the power supply before operating. Improper use, short circuits between solder joints or short circuits between parts can cause damage to the chip.<br /> </span><br /> <p> <strong>Note:</strong><br /> 1. Output power and power supply voltage, speaker impedance, and audio source input size. Generally, the higher the power supply voltage, the greater the output power supported.<br /> 2. Speakers with different impedances can support different output powers. Generally, the smaller the power of the speaker, the easier it is to achieve.<br /> Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
