Car Amplifier With Active Crossover

 

150W amplifier circuit car is equipped with Active Crossover and this circuit using the chip that has a 4-channel power amplifier. Active Crossover function is used to separate the tone of the bass, midrange and treble, the output of direct Active Crossover can be strengthened by the power amplifier.

Power Chip 4-channel amplifier in use is SANYO LA47536 output with output power up to 150W, whereas for Active Crossover using LF353 from National Semiconductor.
