If you want a modern 12-volt radio in a Volkswagen with a 6-volt circuit, then this was previously not possible. But this voltage converter can do, it converts 6 volts to 12 volts. The inverter can be used for radios like our Retro Sound Model One Radio or other devices max. 10 Amps. The minimum dimensions of 130 x 85 x 70 mm can be mounted behind the dashboard. Comes complete with a wiring diagram.
