Here is the circuit diagram of 4 x 35W quad bridge amplifier. This is a power amplifier that has four input channels and four output channels or commonly called the quad amplifier. Power amplifier is designed specifically for car audio system applications. With a fairly large output power per channel, low distortion and low output noise features; amplifier is suitable for your car simple amplifier applications.
There are only a few additional components outside the IC power, so it will not take a lot of space.
About TDA7383:
The TDA7383 is a new technology class AB Audio Power Amplifier in Flexiwatt 25 package designed for high end car radio applications.
Thanks to the fully complementary PNP/NPN output configuration the TDA7383 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced components count allows very compact sets.
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.
