What does AM mean in a car?
2 Answers
AM in a car refers to the radio frequency band. Here is a brief introduction about AM in cars: 1. Composition: Car radios have two modes, one is FM and the other is AM, with FM being the more commonly used one. AM stands for amplitude modulation, while FM stands for frequency modulation. 2. Function: FM is generally preferred in cars due to its better sound quality, while the AM plug is used for connecting MP3 players. The AM band refers to medium-wave broadcasting, whereas FM is short-wave. The car radio, installed as an audio entertainment feature in vehicles, is one of the earliest and most common configurations in car audio-visual entertainment systems.
This AM refers to the most common AM (Amplitude Modulation) radio function in car audio systems. In the past, drivers relied on it to listen to radio stations while driving, as it offers extensive signal coverage and was frequently used during long-distance trips. However, with modern cars now equipped with Bluetooth and digital radio, AM seems somewhat outdated and often suffers from static interference in many areas. Although its sound quality is inferior to FM (Frequency Modulation), it boasts a wider variety of channels, especially foreign language and traffic information stations. I've met many veteran car owners who particularly enjoy listening to AM broadcasts of sports games in their cars—perhaps it's just a habit they can't break. If your car stereo suddenly can't pick up AM signals, check if there's a high-voltage power tower nearby or if you've entered a tunnel.
