sir this subwoffer provides only subwoofer effect what abt left and right speaker how to connect it in this circuit


Hi Pankaj Examine all your wirings transistor pins and diode polarities value of resistances capacitor polarities and so forth. However if You're not in the position to repair the problem and For anyone who is new to building of high power audio projects, please approach any knowledgeable electronic hardware engineer nearer to you personally, by physically viewing and analysing your assembly.

Once the Braun LE01 was positioned in front in the sofa, we played our test playlist by using the Qobuz app by using the speaker’s Chromecast connectivity.

This would be the circuit diagram of the fully transistorized sub woofer amplifier that can produce an output of 100W.There are 7 transistors together with four within the output stage.


What does the gain control do anyway? How should you established the low-pass filter? This article describes the way to tune your amplifier so that your subwoofer sounds just just how you want it to. by Crutchfield's Buck P. Vehicle amplifiers FAQ

Having power to your amp is career one particular after you have come to the decision on where you want it being mounted. As many articles will explain, you should not simply "faucet" the nearest power source. The amount of power necessary for the amp is simply too large, and the tapped wire will not deliver what you need for right functioning.

An amplifier helps optimize your car's audio system, but don't spend someone else to install it. This is definitely an easy DIY project.

I have built this circuit and it truly is working wonderful. I had power up with +/-27 directory volt and sound is very clear and clean. But C2 polarity shown wrongly in this circuit. With wrong polarity of C2 amplifier will not work and R13 will brunt. So keep +ve side of C2 in the direction of GND.


Detailed quality design subwoofer cabinet design formulas dimensions with drawings presented then fret cabin is under construction coming last LM324 made ​​with adjustable active bass filter circuit formulas, details and TDA1562Q made ​​with the amp circuit TDA1562Q Subwoofer Amplifier...

so, I’ll be using a very low frequency pass filter from a pre-built multimedia speaker system. & I don’t have any problems regarding the circuit.

To that point, here are diagrams for two or three typical amp installations to help you see how the many separate components suit together to form an automobile audio system.


pls sir I made another circuit of dis similar amp n I don’t want to utilize these 2n3773 due to insulation challenge, pls sir can u tell me any 3 pin transistor Wich will b as good as d 2n3773 ? I attempted using 2sc5200 but d sound isn’t as good as d 2n3773.

sir i want to make a subwoofer for computer please send out mail me a circuit of 150watt which isn't so costly

As class D car amps are around eighty five% effective and also a/B amps are around 65% or so economical we will use that to estimate the total current an amp would need.
