Hello. Here's a photo. Please note that the inverter drives 6 mosfets, just like in a 6-cylinder car
For this very good - voltage transformer, it's like a perfect gearbox ... A joke, but understandable, right?
The final stages do not matter, because what about their power without a good power supply. That is why the inverter is the most important and here it is very efficient as long as there is a good supply of energy from the battery.
The turn-over, however, is so well-built that the amplifier is versatile without restrictions. It will support any configurations of speakers, sub, etc.
