Default A REAL 1500w amp!

You know these car amps that write 2000w and are smaller than a pizza box?

See what a REAL 1.5kW amp is :

He uses three transformers? Interesting. Definitely a rarity to see flyback type power supplies in car amps.

40A draw isn't that big, though. He's kind of exaggerating it in my opinion

You say it's normal to use 4 AWG cabling?

The power supply shown is for 230V AC input. This is not a car amp.

The multiple transformers are for generating rail voltage, the additional voltage needed for the drivers and the control circuit voltage.

Sure not, but it's showing that most if not every 1500w car amps aren't really 1500w.

I don't think so. Pure marketing BS.

He does suggest the output goes to 77V. This would suggest 741WRMS into 4 ohms.

Ah, something like that for a home would indeed be incredible. There are certainly a few car amps that will put out that power RMS, but they won't be a $100 special at Walmart...
