I think we are getting a little confused here. There is only one power source in these cars, and it is a 12 volt source (roughly). It doesn't matter how many times you connect lines from that source to another component, its still only 12 volts.
If you had 2 12 volt sources, and they were in series, then you could have 24 volts, but our cars only have one source.
