Using Tda7381 audio amplifier IC you can design a very simple 4x25 watts car radio amplifier circuit . Thanks to the fully complementary PNP/NPN output configuration the TDA7381 allows a rail to rail output voltage swing with no need of bootstrap capacitors. As you can see in the circuit diagram , this Tda7381 car audio amplifier require few external electronic components .

To prevent chip damage due to over temperature , you must mount the TDA7381 on a heatsink .
The on-board clipping detector simplifies gain compression operations. The fault diagnostics
makes it possible to detect mistakes during Car- Radio assembly and wiring in the car.
This car radio audio amplifier can be powered from car battery, cu you must use a good filter.
Some of the most important features of this car radio amplifier are :
Short circuit protection , soft thermal limiter, reversed battery protection, esd protection , standby and mute functions .
