I agree with you and get it. Hard to fool real math LOL!! 32a X 14vdc= 448a with no losses. Might have different transistors. I have heard there were some amp builders that played around with using different stuff to get more power back in the day. But not disagreeing with the math of it at all. I'm curious to see what's in it as well. But that is up to the owner to decide whether they want to show their stuff. And I get that as well if it's the case. There are a lot of variables that could be why he is seeing the power he is. Maybe one of the amp builders or techs will step in and help out here!!
