OK... i have a rockford 800a2 one chanel quit working. i opened it up and took my B&K transistor testor and tested that 10 transistors are bad. five IRF640 and five IRF 9640. I replaced them as well as the 10 gate resistors. i was really sure this was all that needed replaced.
well i hooked it up to my aston power supply. all 10 of the transistors i replaced fried within 30 seconds. they got super hot super fast. I Get a voltage reading of around 45+ volts form this speaker output. the working channel I get .3 volts. I am lost now. does anyone have any insight on this.
