Notice:

1. Be sure to check whether the wiring is correct before turning on the power. Be careful of short circuit. The wrong wiring will easily burn the chip.
2. When the power amplifier board is working, it will be hot, don't worry, the chip heat is normal, the temperature of the heat sink is very high, please do not touch it!!
3. The power amplifier board generates a lot of heat! Please pay attention to ventilation and heat dissipation! For a long time or heavy load ~ you can add a cooling fan or change to a larger heat sink.
4. Please do not use small speakers! Ordinary small speakers do not work well! In general, we do not recommend that customers make their own subwoofers unless they are very proficient in speaker parameter selection and cabinet processing. Limited to the actual conditions, it is difficult for ordinary players to make their own speakers with very good results. It is recommended to buy finished boxes to make speakers! Choose large-diameter and high-sensitivity speakers as much as possible.

Package includes:

1 x Amplifier board
