Automotive power amplifier chip TDA7850 is better.
TDA7388 is an ordinary power amplifier chip, 4*40W, most cars are this chip and its copycat chip. TDA7850 is ST's high-end MOS tube sound chip, 4*50W, it is said to have real sound and large thrust. Pioneer's custom model is called PA2030, with a larger thrust of 4*60W. The previous generation of the TDA7850 is the TDA7560, which is also a MOS tube with a slightly smaller thrust of 4*45W and a slightly larger heat.
I recommend the 100W power amplifier board composed of STK3048 and STK6153, its sound effect is really good.
