Is it "dangerous" to pair an Aiyima a3001 with an AIYIMA 48V10A?

I regret having never taken Electricity and Magnetism: several of the terms are beyond my grasp, as well as how they are interrelated. I am considering buying an a3000 to power a bass shaker (or two), and I am curious to know if this power supply will harmlessly boost (or destroy) the a3000?

Thank you, G
 
Quote from Aiyima A3001 technical specification: "DC power supply must not exceed 35V" (for 4 ohm load).
 
You didn't ask, but amperage depends on the load (the amplifier).* It's OK to use a power supply with a higher current rating.

But if the power supply is under-rated and can't supply the necessary current, the power supply voltage will drop and unpredictable "bad things" can happen... The power supply might go into protection mode and temporarily shut-down, a fuse inside the power supply might blow, or the power supply might burn-up and die.

The amplifier will "draw" maximum current when it's putting-out maximum wattage into the speakers.

...There is always voltage present at the power outlets in your home. With nothing plugged-in (or nothing turned on) no current flows. A hair dryer draws more current than a 100W light bulb but the voltage remains (about) the same. If you plug a hair dryer and a toaster into the same circuit, you'll draw excess current and blow the circuit breaker. (If a light dims when you turn-on the hair dryer, the voltage is dropping a bit.)




* Current is also proportional to voltage with a constant load. If you double the voltage into a speaker you also double the current, and that means 4 times with wattage. But with an active-variable load like an amplifier it's not as simple.
