While it does say 1000 watts on the max power output label, it is only rated 185x2 RMS @ 4ohms. Every test of every sony amp I have seen , always did rated plus 10 or so percent extra. The side of the board shown in yer pic is very empty and void of caps and resistors and visual 'magic', BUT if it were to be flipped over you would see lots of surface mount stuff floating around everywhere. They save money by using a single sided board. It will still do well over 500 RMS at 4 ohms bridged.
