[QUOTE="SlugButter, post: 8747251, member: 678073"] The amp would work, but the power supply is an issue. You have to step up voltage, which sounds easy enough, but the boost converters have an issue. When you step up voltage at the outputs of a buck converter, you lose amperage. Rough example: If you have 12 volts and 20 amps coming in at the inputs of the boost converter, and converting to 32 volts, you lose a ton of amperage at the output side running to the amp board. You no longer have the 20 amps you started with at the inputs. The higher you boost the voltage, the more amperage you need at the input side of your boost converter to get voltage up on the output side. The circuitry on the boost converter will likely fail. I have the larger boost converters from Ali express and tried this. I wanted to boost to 12 volts up to 70 volts, which works, but they have a 20 amp fuse at the inputs of the converter. When I boost the power to 70 volts, it works, but I’m only getting 70 volts and 2 amps at the outputs with the 12 volts and 20 amps coming in at the inputs. The amplifier board needs more than 2 amps to run, so once the amps pull the power it needs at the output, the input spikes over 20 amps trying to supply the boosted side, the fuses blow. The power conversion process is way too inefficient to realistically spend much time doing it. [/QUOTE]
