A challenge to installing a computer in a car is the power supply. Energy is supplied as a nominal 12 VDC in cars or 24 VDC in some trucks.

There can be peaks, and at ignition time the supply current drops.

Every amplifier has a rated power level sometimes noted on the head unit with the built-in amplifier, or on the label of a stand-alone unit. Coaxial speakers: These are the most common type of car speakers and are often factory-installed.

Wireless CarPlay works by having the phone exchange network credentials with a supporting CarPlay receiver over Bluetooth, establishing a two-way Wi-Fi connection.
