Nowadays, many car owners choose to do car audio modification in order to achieve better sound quality. With the increasing demand, the profession of car audio modification in Chengdu has also ushered in a new development. As is well known, upgrading car audio modification is a very complex project, so there are requirements for each component. Today, the intelligent Bluetooth shoe light will talk about the requirements for power amplifiers in car audio modification.

1. Firstly, it is necessary to have a good power supply, which is the key to determining the sound quality of the amplifier. The power supply and amplification parts should be designed separately to reduce noise. Choosing a large step-up transformer to supply stable current, as well as a large capacitor, can respond more quickly and supply the required current for amplification.

2. Secondly, it is necessary to have a built-in parameter equalizer. Car audio systems are very different from home audio systems, and the placement of speakers is very limited, making sound adjustment very important. In addition, due to the sound blocking effect of the headrest and car windows, as well as the disturbance of sound waves caused by the perspective of the low pitched speaker, the sound effect of the car audio system can be affected.
