LM383 Power Amplifier OTL 5.5W For Car

This is CAR Power Amplifier circuit,It is a simple circuit that good Idea for real beginner.
I uses IC number LM383 OTL Amp is main ‘s circuit, It has power output 5.5W min at speaker 4 OHM and Voltage supply 12V-14.4V.
It has body same the TDA2030 so should attach with heatsink, when it work will very heat, may be damage.

4x34W car audio amplifier based on TDA7384

This is circuit power amplifier for car. use IC TDA7384.
Output power 34Wx4 at speaker 4OHM.
read intro detail:

So this time I decided to make pretty simple but powerful enough audio amplifier. For this I have chosen quad bridge car audio amplifier TDA7384 which has four input and four output channels with power capability 4x35W.

If connect to car battery where operating voltage is about 13.2V, then each channel can give 22W what is more than enough for me. This amplifier I probably will use to test audio processor TDA7313 which is stil in development phase. I did not find much information about this chip on the internet so I decided to built it and try on my own.

4×22W car audio amplifier based on TDA7384

As datasheets of TDA7384 says it is low distortion, low output noise, low external component count. Also has Stand-By function and Mute function. It has several protections like from output short circuit to GND or to Vs, capable to handle very inductive loads, thermal limiter, load dump voltage. TDA7384 is an AB power amplifier cased in flexiwatt25 (eagle library is included in project archive) package wich is designed for high end car radio applications. It allows rail to rail output voltage swing with no need of boot-strap capacitors.
