Friends

I live in Brazil, even here there is this culture of installing PCs in cars with GPS, consoles and screens of LCD.

I want to install an XBox in one of my cars, need information, energy converters, chaveadores to switch the sound of the panel for the sound of the XBox and other pertinent information.

We have used the search engine of the Forum but did not find more information as sketches, diagrams and materials needed.

Any help will be welcomed.

Thank you
