I have a car amp that is rated as 20 wpc rms. I plan to use it indoors with
a 12v ps. How many amps should i need? Thanks.

Is there a fuse on the amp?
Use a 12v power supply that is a little higher than that
If there is a 15 amp fuse on the amp use a 20 amp power supply
20 amp fuse, 25 amp supply etc
The bigger the power supply the better
