Review on 🔌 Universal Regulated Switching Power Supply - SUPERNIGHT DC 12V 30A 360W, AC 110V/220V to DC 12V Power Driver for 3D Printer, HAM Radio Transceiver, Car Subwoofer Amp, Audio Amplifier and RC LiPo Chargers by Buddy Camaney

I am using two of these in a parallel arrangement to power a 2500w car audio amp on a garage dyno. At first I thought 60 amps would be enough, but as I get closer to the mid-band of the amp's power range I need more, around 100-120 amps, to power it properly. Surprisingly, both devices hold 13+ volts at the output until the moment of overload, but then they don't immediately go into "protection mode". Instead, they continue to consume the available amplifiers even when the amplifier voltage drops. At the intersection of a power supply's peak power output and the amplifier's maximum available power (determined by the distortion that occurs when the loudness of the sound pushes the waveform magnitude out of the woofer's power rejection zone), these power supplies still don't give up. ! When I turn the volume down just below overload using the best bass boost test tracks I can find, the two power supplies definitely pass the endurance test at the highest possible amperage while remaining surprisingly cold. I have ordered two additional identical power supplies and will be redesigning my stack to take advantage of the superior performance of these units while making the most of the limited rack space. After repeatedly and torturously testing these devices, I definitely recommend them!
