Subwoofer amplifier circuit 3X150 Watts:
This is a Subwoofer amplifier circuit 3X150 Watts. this diagram can make 3 outputs. we can use 2 outputs for the left speaker and the Right speaker and another for the Subwoofer output. for this, we have to use a lowpass filter for bass output. lowpass filter will make only bass for the woofer speaker. Here is the link for the lowpass filter
1 number and 6 number leg for High voltage and 2 number and 5 number leg for the Low voltage. this diagram needs dual voltage. high+low+Gnd+low+high voltage. positive high voltage positive low voltage. negative high voltage negative low voltage and the Ground voltage. the low voltage should be 30v to 45v. and the high voltage should be 60v to 80v. this diagram is for 10 STK ICS. These 10 STK outputs are not the same. STK413-000 can make maximum 150w+150w. the 3 inputs are raw sound. we have to make the sound bass and surround. it’s like a 2.1 audio diagram.
This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. 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.
