[@peterjansen5498]

7000W LOL. The so called power supply polarity changed between 8.47 and 8.58 and back again during the "demo". Capton tape does nothing as the transistors are screwed directly to the heatsink. Capton tape around the battery casing. My suspicion is there is a bluetooth module, small amp and battery inside the larger battery housing. the audio is fed virtually direct to the speakers via those heavy copper wires. The FET's do nothing. Love these vids. So much fun working out how it doesn't work.

[@vincentrobinette1507]

Just a few concerns: First off, even though you used Kapton tape to insulate the low side transistors, the transistor drains are still connected to the heat sink, via the screw heads and threads. Second, both the input and output capacitors are reverse polarized. (both hooked up backward) Third, I don't see any pull up current to turn on the high side MOSFET's. The 270 Ohm resistor connected to the base of the D718 transistor is going to pull the gates of the high side MOSFET's down hard, regardless of input signal. The collector of the D718, will just pull the low side transistor gates to ground, turning them off as well. The emitter-base junction voltage drop is only ~.6 volts. It's just like a diode, with the cathode connected to ground, the anode connected to the 270 Ohm resistor. These are enhancement mode N-channel MOSFET's, so, to fully turn on the high side transistors, you need some kind of bootstrap circuit, to drive the gates at least 5 volts(a bootstrap circuit would give you 6 volts, if you are using a 12 volt battery) above the positive rail. I'm not seeing any kind of auxiliary supply, or, capacitors to shuttle the voltage from the output to the high side gates, to turn on those high side transistors.

[@pawelczarnecki7780]

I agree ☝️

[@Uraim]

i agree, also if he saying that ha having 7000Watts, and he he having one 1ohm speaker and one 2ohm speaker, he having 0.67ohm load. so if we calculate performance with ohm law, we would need: 69V and 103A on output (0.67ohm load.) 84V and 84A on output (1 ohm load.) 119V and 59A on output (2 ohm load.) Ofcourse we would get a little bit of resistance on the wires and components, so it would need a little bit more voltage. The whole amplifier doesn't make any sense. He having 12V input from battery, 1-2 Mosfet would be enough. if its a class A amplifier, the efficiency is arround 25% and the output voltage is 3V. on 0.67Ohm load, it is 13Watts. if its a class AB amplifier (unlikely), the efficiency is arround 50% and the output voltage is 6V. on 0.67Ohm load, it is 53Watts. if we having 90% efficiency which is imposible, only class D amplifiers can do that efficiency, it is 10.8V. on 0.67Ohm load, it is 174Watts. I think its a class A amplifier, The speakers dont have a loot of move, and these speakers are only 200 and 300Watts. The 2000 and 3000Watt car audio subwoofers are brutal, their weight are up to 20kg each, box not included.

This is low-fi. You need a high pressure vacuum tube push-push stage to drive your output stage. Think bipolar speakers, Mirage, Eclipse BP etc. Also, no transistors from broken ebikes and personal massage units Get some lateral FETs, Black Gates, Serpentis Oleum for smooth moving coil coupling. Just use a normal MMC thats tuned to the exact eigen takt of your room or house. This way its self exited and this provides very high ritalin effect in the standing WAveguide for Negative Koeffisient Erroneous Refractivity. If mmWave = active, goto "RattleLube". What cable did you use to transfer music or power? This must be audiophile quality or bit-perfect is no longer 1s and 0s, but maybe 0.98s and 0.3s. Its common knowledge that a computer must have 0 and 1 for binary refinement state. Integers and floating point is different, and the difference is called delta. For temp is deltaT and for bits in binary code its delta-integerale. This is the push-push with no compression loss. Force instead of lossy compression. Übermacht immer gewinnt. The most important factor is the wifi and the ethernet its connected to. Only 10/100baseT with solid aggregate state and Alligator Arresters. NO UPS. Uninterruptable PSU needs to be 50% interruptible to allow proper function of interrupt requests (IRQ) in the asynchronous audio transmission. Rifa, ROE, Elna etc does not work in PSU. Only reverse biased tantalum stacks. Hundreds of uF with reversed bias stacked tantalums not only sounds great, but all those orange caps soldered nicely together looks awesome. Better than High-End is Sky-End.

wait a moment! why you use this yellow tape? as an isolator? really? do not think so, the Drains go to touch the heatsink anyway! just because the screws have no isolation and connect both surfaces! nice try! hehehe and almost forget it...finally you decided where to connect the battery red cable!

[@vincentrobinette1507]

Did you by chance notice, both capacitors connected backward? or, the fact, that there is no pull up to bias the high side MOSFET's? This just can't work as shown.
