How are car audio systems classified?

[Craig]

Car audio systems can be classified in several ways: 1. By the time of vehicle production, they can be divided into original equipment and aftermarket products; 2. By the regional origin of the brand, they can be categorized into Japanese brands and European/American brands; 3. By the manufacturer's specialization, they can be classified into dedicated car audio manufacturers and diversified manufacturers that produce both car audio and other home appliances. A car audio system consists of five main components: antenna, receiver, speaker correction, audible frequency amplification, and speaker system. The antenna receives radio waves from broadcasting stations and transmits them to the radio tuner via high-frequency cables. The receiver selectively picks up high-frequency electromagnetic waves from radio stations and demodulates them into audio electrical signals. The speaker is the crucial component that ultimately determines the sound performance inside the vehicle cabin.
