Amplificador de 80 watts RMS para el Automóvil:

This is an amplifier circuit diagram using the TDA2004 IC. Amplificador de 80 watts RMS para el Automóvil. This circuit can make 25 watts in bridge mode. In stereo mode, it can produce 10+10 watts using 12 volts. Typically, this circuit diagram is used in car audio systems. We can use 12 12-volt batteries. The maximum we can use is 18 volts.

PCB Power Amplifier 1000Watt:

This is the PCB Power Amplifier 1000Watt. This circuit can make 1000 watts using 8 transistors. Here, use 2sc5200 and 2sa1943 transistors. This pair of transistors can produce a maximum of 150 watts. We can use 25-0-25 voltage to 60-0-60 voltage. We can also use another transistor. We can use any of the PNP and NPN transistors.

PCB Power Amplifier 1000Watt

This is the Speaker protection circuit diagram. It can protect our Speaker from burns. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
