Need Power Supply Requirements To Power 500w Car Amplifier

I am doing a project, and need accurate power supply requirements/specifications. I am hooking two 12'' DVC sub woofers up to my computer. I need a power supply that can power the amplifier without issues. Please check this link to see more details and what I am needing/doing/using:

Can car amplifiers even operate from a switching power supply?

Yes. I have read of many people doing it, and many online guides say to use one as cheapest solution.

well realistically you need a 14 Volts or so... and you are going to be pushing this off the 12V rail of a single psu? You are going to need a power supply which has over 42 Amps on a 12V rail... and i dont think its good to only drain 12V from the psu... but whatever.

Wouldnt a pair of car batteries and a charger be a better solution... maybe i am not seeing something though
