unipolar to bipolar conversion

[Splynncryth]

I did not see any topics on this subject in the search. I don't think DACs count as power supplies. Sorry if I'm just adding to the noise.
I'm building a circuit for use in automotive apps that bears a resemblance to an audio circuit. The problem is that I need a bipolar supply. I want to keep the part count lo so the end result can be built into a small package. The system will function just above the audio range and will not be driving a speaker. I'm not looking for tons of current here either, I haven't pinned down any specs yet, but I doubt I'll exceed 5 amps, if I even get that high. Any simple solutions for converting to bipolar and regulating that power? I'm working on a 10 volt rail to rail assumption now, though adapting the system to handle a little more votage if I can get it and cut down on the current.
What solutions are avilable?

What is your load? Is it grounded or can it be floating? Is it a motor you want to rotate in both directions?

If you don't want to fix negative voltage you have to consider a bridged solution, linear or PWM.
