Not familiar with how much voltage and current car amps put out, but I always thought the voltage was relatively low, but the current was much higher. Alternatively, I've been thinking that vehicle power inverters (12VDC to 120VAC) could be a source of "inspiration". AFAIK, those as basically oscillators with step-up transformers. With a different-sized transformer and some rectification & filtering, I should be able to get this done.
