Bro can not use 7A its too much trasistors can not handle .

The power output would be the same if it was 12V 7A, or 12V 2A. The amperage the battery can supply is just that, what it can supply, not what the circuit consumes.

Good Morning, Creative Channel PRO; Congratulations on the video. Very well explained. Please. How many watts is the output to the speakers for each channel? Awaiting. Thankful.

[@creativechannelpro371]

Thank you so so much Dear friend sorry friend Wattage is not confirmed I Think 10W - 15W each Channel

[@AstrosElectronicsLab]

@@creativechannelpro371 doubtful. Assume a maximum voltage of 12V for the supply, and around 6V p-p at the output because of how inefficient this circuit is. If each speaker is 8 ohms, then we take half the peak-peak voltage, which is 3 ^ 2 / 8 = ~1W. This, would be probably closer to being correct.

Any power transistor with a Hfe of around 160, collector voltage in this low powered instance is irrelevant, but you'd want a collector current capability of around 5A should do. So, TIP-35C/TIP-36C, 2N3055/MJ2955 for example.

Sir can I make 5watt 4ohm stereo speaker same with you invention

[@creativechannelpro371]

Speaker may burn not good

[@AstrosElectronicsLab]

I would say the output would be closer to 1W of amplifier, so should be fine. However, there's DC voltage flowing through the voice coil of the speaker all the time being Class-A, therefor the speaker would burn out after time anyway. This is a very BAD implementation of an amplifier. Really should be an output transformer in place of each speaker driver.

[@vipervidsgamingplus5723]

by running the speakers in series wouldn't that reduce the ohm load on them by half

[@creativechannelpro371]

Thanks for your information friend

[@AstrosElectronicsLab]

Well, no. The positive "rail" is on each positive speaker post making this the "common" rail (most normal single-ended amplifiers use the negative rail as the common). Therefor, the speakers maybe in series with themselves (albeit reverse polarity to each other), but to the circuit they're considered separate.

[@creativechannelpro371]

Friend thanks for your great information😃😃😃

[@creativechannelpro371]

Yes friend may be distorted but not feel to much

[@AstrosElectronicsLab]

That's because it's not biased correctly. And, if I'm not mistaken, this is a Class-A amplifier; DC power shouldn't be running directly through the voice coils of the speakers.

[@AstrosElectronicsLab]

@@creativechannelpro371 DC is going through the speaker at all times. Any speaker will be destroyed after time. An output transformer would solve that issue. This is Class-A, so the "150k" resistor should be chosen so that half the supply voltage appears between +V and where the negative speaker terminal is. This should clear up the distortion. You're probably looking at a resistor value closer to 1M.
