using car amp as subwoofer amp

[craig7]

so, i just bought a 300 watt car amp (scosche sa300) at walmart for $50 and ive seen videos of people using car amps at home and i want to know how to do it, the ways ive seen use pc power supplies which i have two of so what do i need to do. one of the power supplies is 300 watts so do i need to use that one or can i use any one?

You can use a power supply but don't expect to get the best preformance from the amp. They need a big power suppply to do well, and they aren't cheap.

They are only as good as the power supply they use and by the time you get one that's strong enough to "work" OK with it, you might as well have bought a plate amp from PE or Madisound.

It'll work but probably not work very well ... really depends on what you expect to get out of it.
