View Full Version : alpine pdx power supply

I have 3 of the newer alpine PDX amps, 1 f4 and 2 m12's. I know they are digital and provide the same power at any load between 2 and 4 ohms. I was wondering if they had a regulated power supply like jl amps, meaning they can put out that same amount of power at 12.2, 13.8, 14.4 volts etc, all I found on alpines specs was what they called it as resonant mode power supply. I'm not really sure what that means
