I think that the TDA7377 amplifier has high performance compared to the price of the amplifier that does not know how to integrate a previously shared @gevv simple application; 2X30W Anfi Circuit with TDA7377
TL074 opamp is used on the ton control floor of the project DC rectification filter is on PCB Solid voltage of lowest 8v DC at the highest 18v DC … You can use 50 … 60W transformer with 12v AC output.
I used an old ATX power box for boxing ATX boxes are very helpful for this kind of operation. The circuit was compatible with all ATX power supply casings, at least to the bend. I only struggled to cut out the cooler size did not hold. The transformer stands out from an old 5 + 1 system at about 70-80W. Enabled chassis where it says must be connected to the box hooked. I bottom cable and the cable end with the screw as pictured. In fact, depending on the punching height of the pods, the plaque can be connected directly to the screw holes.
Check tons of solid medium ( medium volume setting ) Lower ( treble adjustment ) over the leg of the PCB as you can see in PCB capacitors that are connected to potentiometers can be worn under or image by isolating the sleeving.

TDA7377 ANFI CIRCUIT SCHEMATIC
The TDA7377 is a new technology class AB car radio amplifier able to work either in DUAL BRIDGE or QUAD SINGLE ENDED configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with the extremely reduced component count. The onboard clip detector simplifies gain compression operation. The fault diagnostics makes it possible to detect mistakes during car radio set assembly and wiring in the car
TDA7377 Protection Systems
- Load Dump Voltages surge
- Reversed Battery
- Output DC Short Circuit protection with the low current when shorted to GND or VCC.
- Output AC short circuit protection: across the load
- Silent Turn On/Off
- thermal shutdown
- Load very Inductive speakers
- Fortuitous Open GND
