1. The power interface is embedded with a reverse protection unit, and it will not burn when reversely connected. 2. The output power depends on the power supply voltage and speaker impedance. For high-power situations, the recommended voltage is 24v and the current is greater than 5A. Try to use 4-ohm speakers, which is beneficial to high power. 3. Each speaker must be packed in a box. It is recommended to use a finished box for subwoofers. It is more complicated to make your own and it is difficult to achieve good results | Please strictly distinguish between positive and negative channels. Reverse connection will seriously reduce the sound efficiency.

4. The speaker output is a BTL structure, and it is strictly prohibited to use it on the same ground, otherwise the sound will be abnormal and the amplifier may be burned.

5. How to judge the noise floor: short-circuit the input terminal, connect the speaker and listen. Normally there should be only a very weak noise (generally not obvious about 50 centimeters away from the speaker). It is too loud and abnormal. If the noise increases when connected to a computer or mobile phone, it means the noise comes from the signal source.

6. Dual channels support 4 ohm 50w and 8 ohm 30w speakers, and the bass supports 2 ohm 100w speakers.
