As a more and more popular means of transportation, cars have occupied more time and space for human beings and have become an indispensable daily necessity. As the only part with entertainment function in this driving tool, the original car audio sometimes cannot meet the needs of some drivers who have high requirements for music, so car audio modification has become a more important thing.

1. Car audio amplifier The power amplifier is also called the power amplifier, which is responsible for amplifying the power of the front-stage audio signal and then driving the speaker. Most of the power amplifiers built into the host generally have very small output power, and their sound quality cannot be compared with that of external power amplifiers. If you want better sound quality or drive a higher-power speaker, adding a power amplifier is indispensable. Power amplifiers can be divided into Class A power amplifiers, Class AB power amplifiers, and Class B power amplifiers according to their structure. If they are divided into single-channel power amplifiers, two-channel power amplifiers, three-channel power amplifiers, four-channel power amplifiers, and five-channel power amplifiers according to the number of channels.

2. Car Audio DSP Processor DSP amplifier, also called DSP digital amplifier, uses DSP chip, which can adjust the parameters of each channel through computer. The biggest difference from traditional amplifier is that DSP amplifier can be better managed through computer, while traditional amplifier cannot do this. DSP amplifier has the functions of other amplifiers, and can also attenuate the overlapping frequencies caused by the car environment, and the attenuated frequencies can be added, and can also adjust the distance between each speaker in the car and the human ear. DSP amplifier mainly has delay processing, EQ adjustment function, and frequency division function. It can adjust the defects in the car that cannot be adjusted physically, and completely improve the complex audio environment in the car, making the sound quality clear.
