Hifi digital stereo audio power amplifier board, DC 12-16V power supply; 50W x 4 output power; High-Fidelity sound which gives you enjoyable experience
TDA7850 chip as the core (VC3121 chip as assistance); the chip''s surface touches the cooling fan''s metal surface, so the cooling fan works more sensitively
Intelligent cooling fan will work when temperature is more than 25℃ and off when tempareture is lower than 25℃, attached elastic ''seat foot'' which is in convenient for you to install
50W*4, high power; easily drive 10'' speaker, providing clear and fine sound; Four output channel let you enjoy 360°stereo sound experience; More lifelike and moving
Double isolation: Audio signal circuit is separated from power supply circuit, avoiding mutual conflicts and interference, with fidelity; no ''POP'' sonic boom when turn on/turn off
