Description: 
The power amplifier circuit board designed using the official standard. The chip uses a selection of US imports original Longing micro Class D amplifier chip. Good product chip is necessary and the majority of music lovers to share. This is our consistent philosophy. The amplifier has ultra-high efficiency and large power output. In the case of 12V power supply, it can amplify output 10W + 10W of power. The chip is without fins, but without overheating as well as over-current protection function, the product can be said to be very powerful. 
It seems difficult for this amplifier board to drive two 15W speakers. High efficiency Class D amplifier board pure does not blow out. It is most suitable for listening music in small rooms.
