tyre
Tires are also very important, because strong power and sensitive braking are ultimately achieved by the grip of the tires. In addition, more professional racing cars use different tires on dry roads and in rainy days. Cross country racing puts forward higher requirements for tires
ECU system
When the car leaves the factory, it is considered that the car will be sold all over the world to adapt to different environments and oil quality, so the program in the original ECU is the best compromise to meet many conditions, that is, at least 30% - 40% of the energy is sealed (especially the European cars famous for safety). In particular, it can achieve unexpected power improvement effect on the ECU upgrade of turbo vehicles.
sound
The door should be soundproofed, and the sound field should be considered in the arrangement of speakers
In terms of sound modification, power amplifiers, loudspeakers and other modifications are very important. At the same time, the installation position and layout of sound equipment will also have a great impact on the sound effect. This is just like cooking. You need not only good raw materials, but also superb cooking skills to cook good dishes with excellent flavor.
Door sound insulation
One of the biggest differences between listening to music in a car and listening to music at home is that the car is moving fast. In order to achieve good results, this puts forward higher requirements for audio equipment. At the same time, wind noise, tire noise and mechanical noise will interfere with the audio system when the car is running at high speed. Therefore, the vehicle needs to be modified. Generally, doors are selected for shock and sound insulation. Door sound insulation can be done in many car modification stores and car audio stores. In addition, the sound insulation of the door can also form a box for the horn, so that the sound of the horn will be gathered, making the music played by the horn more real without distortion.
Door seal
Generally, soft foam sponge is used to seal the door cavity. The best effect is to use a professional shock plate, but the cost of the shock plate is much higher than that of the foam sponge.
The location of the loudspeaker is particular
When the car stereo is refitted, the high, middle and low speakers should also be independent. If they are installed together, they will only interfere with each other. For example, when an Audi A6 car owner modifies his Audi A6 audio, install the tweeter on both sides of the A pillar, the mid-range speaker on the front of the middle of the front door, and the bass speaker on the bottom of the front door. According to the modification technician, this is conducive to the connection between the high and middle tones, forming an accurate positioning of the sound field. Moreover, this modification did not damage the original vehicle parts and could be disassembled at any time.
Smart layout of speakers
Many car owners choose to hide the speakers when refitting and use built-in speakers, which can also save space and is a very practical choice. At the same time, the speaker with irregular shape can also be selected to maximize the use of space, and the irregular shape is conducive to eliminating mutual interference between sound waves.
