HIGH_POWER_AUDIO_AMP_FOR_AUTOMOTIVE_INSTALLATION

Two of these audio amplifiers can be used to make a stereo amplifier 200W per channel. IRF640 and IRF9640 power MOSFETs are used to drive the output load, which might be 4 or 8Ω. Response is 12 Hz to 45 kHz (-3 dB), THD <0.1%. Power is supplied by a switching-type power supply, which is external to the amplifier (±47V). About 600 W total power (peak) is needed.
