Default A good 12v power supply to run small class D amplifier indoors?

I bought a small Class D car amplifier that will deliver 210 watts at 2 Ohms at a current draw of 25A? Not sure but I tried my dads batter charger that will 40A and 200A for starting cars and it powered my little amplifier real good and the bass was kicking but I had to give it back because it was not mine. I was going to try a computer power supply but it's not enough current for the amp to function good.

Any good cheap 12v power supplys you can recommend? I'm not sure about brands and all that jazz but that 12v car battery charger did the trick.

Is there anything similar to the car battery chargers power output? And that's is pretty much afordable?

Thanks your help.

When I test large power amps for cars after repairing them I use a 60Amp (continuous) battery charger and a 21A/h motorcycle battery as smoothing.
