@@NurulAini How would you get 12V sin out of 12V battery? You can't square it. You'll maximum get 12Vpp from a 12V battery and therefor maximum get 4,2Vrms => 4,2^2/8=2,25 Watt/8 ohm
Good Job, 😊 but there is a down side about this project of yours😅 The Spk Output Produce DC, passing through the Spk which cause the voice coil of the Speaker to burn after a long period of Test..
Its fake... there is a amp and bluetooth receiver inside the battery, the so called circuit is just passing the signal through that fat capacitor. thats why the value of it is so high Its the same battery he is using in all the projects... its been taped back together... does not even make a solid thud on the table... its hallow with batteries inside with a small D-class amp and a BT receiver...
May I ask what the point is of using Kapton tape to insulate the collector-case terminals (center pins) of the two transistors, when you are using metal (electrically conductive) mounting screws, without any insulating washers on the screws? Some thermal grease placed on the transistor to heatsink junction would be helpful in transferring heat away from the transistors, BTW! Additionally sir, since your "amplifier circuit" is single ended (one 12 Vdc battery), the theoretical, maximum power (Wattage) will be constrained by the maximum Voltage available, which as stated is limited to 12 Volts. The title of your video states "Powerful Ultra Bass Amplifier". I do not believe that 10 Watts, at most, qualifies as "Powerful". Perhaps my standards are slightly skewed, but still, "Powerful Ultra Bass Amplifier" is really over doing it just a bit, don't you think? Finally, you have no (zero) DC blocking in the audio output of this amplifier design... From what I can gather, from your floating in air connections, you will be maintaining a constant level of DC on the output connections, which will manifest in slow cooking of your speaker's voice coil, over a short amount of time (just a friendly heads up, in case you might want to continue using your loudspeaker for more projects in the future).
Fred, its fake. If you take notice the ground connection for the audio cable was not even connected. the 2 ground connections "speaker and power" are just shunted through the improperly connected transistors. the 25V 330uF capacitor is allowing the internal amplifier to pass the audio signal thats why there is no high/mid range... its sounds flat. the battery he uses is in all his "so called high power amp vids" it contains a BT module, maybe a small 10Watt Class D amp, and a Li-Ion battery pack. pay close attention to the vids, the battery has been taped, cause it was hallowed out to hide the parts needed.
I thought it was going to be a "see how many people I can kill" video. Here is the circuit diagram and how he made it look as if it worked. ua-cam.com/video/zSGp0fKQTkA/v-deo.html
Only thing is your missing the low pass crossover otherwise you'll be blowing your subwoofers. Subwoofers don't have passive crossovers built in to them. At least most don't anyway. You need to the cutoff to be somewhere in the 90hz range Expeacially if you're running 10's or 12's if there 8's or smaller then you can run up around 120hz or maybe even around 150hz. But subwoofers aren't designed to produce anything but really low deep bass.
he would have to put the low pass crossover in the battery case where the true amplifier is hidden. Here is the circuit diagram and how he made it look like it worked. ua-cam.com/video/zSGp0fKQTkA/v-deo.html

I don't know how you get the speaker to play with one of the input wires broken off. There's no way that speaker should be playing at all, at least not through that thing you built.
battery contains amp and power source along with bluetooth receiver. there is a noticeable delay from pressing play and the audio. The audio has no mid/high range cause its being filtered off by the 25V 330uF capacitor
