But he said above even in unbridged mode it would still cut out because of overheating. I guess I'm just confused on if Class D is supposed to be 85-90+ efficient over A or A/B designs which are in the 50% or less range, no case for trapping the heat, and 4 ohm compatible, why the issues?
Are the heatsinks those little strips of silver metal in the pictures, or were the real heatsinks removed for the pics ?
A class AB (typical amp) with that power rating would have heatsinks the size of your head (ie a lot more than 10x the size of the heatsinks in the pics) wouldn't it ?
