DIY car amplifier circuit:
This is the DIY car amplifier circuit diagram for the car audio. here use TDA2004 this IC can make 10+10 watts in stereo mode but this circuit makes it In bridge mode. in bridge mode, this Ic can make 25 watts max. here in this diagram used 4 Ic for 4 output channels. the input is stereo but the output is 4 channels.
The voltage is 12 voltage. this diagram has 4 graphic equalizers to control the sound quality.
The circuit diagram is
This is the Speaker protection circuit diagram. It can protect our Speaker from the Burn. if the amplifier has any problem then this circuit can save our soundbox. Normally when the transistor makes a short circuit the voltage comes out from the speaker output line then this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is very important for protecting the speaker.
