The amplifier increases and stabilizes the 12V power supply, and the set value is 16V when the power input supply voltage is from 9V to 16V. The amplifier can output a stable 16V voltage to the amplifier chip to achieve the maximum potential of this power amplifier chip (4x35W 1% to 4x47W 10% distortion) to adapt to most speakers (horns) Sold by the market supplier Appropriate power matching
This device uses a power amplifier chip with Cmos as the power output (attention: triode output chips are not available on this platform)
This device supports 4 integrated balanced higher-level inputs, 4 balanced high and low inputs, and 4 modeled adjustable equalizers.
This device has excellent protection against impact sound off and on, as well as overheat and overload protection circuit

Android radio amplifier

1. With Android car stereo 16-pin standard cable.
2. The amplifier inside presses the voltage to 16V, so the power amplifier chip would have a higher output power, so the output sound will be louder and more dynamic.
3. With subwoofer output ports, you can connect to a subwoofer.
4. Simple and convenient to use knobs for adjusting treble, midrange and bass separately, very convenient for tone adjustment.
