The car audio system is equipped with a playback device to reduce the monotony of driving and passenger travel. The earliest use was car AM radio, later developed into AM FM radio, cassette player, CD player, and compatible with DCC and DAT digital audio. Nowadays, car audio systems have reached high standards in terms of sound quality, operation, and anti vibration, and can handle bumps on bumpy roads, ensuring stable functionality and sound quality.

Today, I will mainly talk about the types of car audio dividers?

Frequency dividers can be classified into different varieties according to different classification methods:

According to the circuit connection method of each unit in the frequency divider, it can be divided into series frequency divider and parallel frequency divider. Nowadays, parallel frequency dividers are commonly used in the industry, and their main advantage lies in the fact that in multi-channel speakers, each can be regarded as an independent part. If a series splitter is used, any component may affect the high pass and low pass characteristics. The frequency dividers discussed in this article are all parallel type dividers.

According to the level, it can be divided into high-level dividers and low-level dividers. A high power divider is also commonly referred to as a passive divider. It refers to a high-power signal amplified by a power amplifier, which is then divided and output to a specific unit through a passive divider. A low-level divider, also known as an active divider, is composed of active electronic high pass and low-pass filters, usually installed in the front stage of the host or power amplifier.

Other classification methods for frequency dividers include dividing them into high pass, bandpass, and low-pass dividers based on the replay frequency, and dividing them into first order, second order, third order, and fourth order dividers based on their electronic components and attenuation slope.
