When installing a new radio or speaker system, it is important to ensure that the amplifier is compatible with the new components. Failure to do so can cause the system to malfunction or even damage the car’s electrical system.
Antenna
The antenna is the component that allows the radio to receive signals from broadcast stations. In the 1999 Mercedes E320 radio wiring diagram, the antenna is located on the top of the car. The antenna receives signals from broadcast stations and sends them to the radio, where they are converted into sound.
When installing a new radio, it is important to ensure that the antenna is connected correctly. Failure to do so can cause the radio to malfunction or even damage the car’s electrical system.
Speakers
The speakers are responsible for converting electrical signals into sound waves that you can hear. In the 1999 Mercedes E320 radio wiring diagram, the speakers are located in the doors and rear deck of the car. The speakers receive a signal from the amplifier and convert it into sound.
When installing new speakers, it is important to ensure that they are compatible with the amplifier and radio. Failure to do so can cause the system to malfunction or even damage the car’s electrical system.
