I am new to the art of gaincloning, as well as to this forum, and planning to build an car amp. What I don't grip is how to get +/- voltage from a single battery setup. Is it possible?
See for example, http://sound.westhost.com/project89.htm
This is an advanced project. You will need an oscilloscope, ability to wind a custom transformer, and the ability to make PCB's to build this sort of thing. If that is beyond your scope, do not attempt it as you risk causing a fire in your car.

A bit to advanced I'm afraid. One thing that puzzles me is how to connect ground from the amp because to my understanding - and ground will be the same thing on a cars electric system, or have I missed something?
Not sure what you mean. The amp ground would connect to common ground, which all ends up connectd to the car batterys negative terminal.
Two windings with earth in the center maybe or something like that . Anyway, it's possible to keep the transformer small due to higher switching frequency, it's not 50/60Hz anymore. So basically, chop voltage to pieces and push-pull it through a transformer then rectify it and feed back to know what pulsewith to use. Or if it's boost converter without transformer, it's almost like, draw current through a coil and take care of the higher voltage that comes back when releasing the tension ,due to the nature of a coil. but then it will be somewhat tricky to get a negative voltage.
Anyway I put some simple diy amplifier inside a friends car amp, ripped out the original amp. board first and used only the dcdc, worked very good, lets just say that the dcdc must have been better than the amps in that box.
