IRAUDAMP 9 with 1700W 2 OHM - IRS2092 IC - who build an test

i can´t tell you if it´s better or not than irs3000ucd ot aud600 , because i dont have them to compare .But it has already a year working without any failure.The sound is very good, good bass, but ,since it is pre feedback, all dependence of filter quality is a reality.
Had to make three different pcb to work without protection hiccup.
