Default Car Power Supply for BA-1 or BA2?

How can I design a power supply from a car battery 12.6V?
Are they any examples?
I have an early Soundstream amp that Nelson designed.

Here is a nice PSU that will generate +/-22V out of 12V - enough for 20W @ 8 Ohms:

There are a few SMPS supplies on Ebay designed for a car, here is one. It is probably higher DC rail voltages than you were looking for, but I know there are others on Ebay.
