If you search "DC-DC buck converter" you'll find something.

Just have to watch as at least one new stereo I've seen (sony I think) has the "constant" (what used to be "memory") power as the main feed, and the ACC is just a trigger. So that would smoke the original converter unless you did some bodgy workaround with relays.
