Because people do not know enough about car audio, some people even think that car audio modification is a very simple matter. As everyone knows, car audio is only a semi-finished product, and we still need to install it to make the audio system play its charming sound charm.
As the saying goes: Three points for equipment and seven points for installation and debugging. Car audio modification is a comprehensive technology and art. First of all, we must have certain knowledge and practical experience in car circuits and audio circuits, so that the performance of the car cannot be affected by the installation of audio , nor can it bring safety hazards to the car. The purpose of audio modification is to have sound effects, and the installation quality cannot be ignored for cheap. Of course, we all want to spend the least amount of money to get high-quality audio equipment, and improper installation and debugging often cause various failures. During the installation process, the structure of the car will be damaged, leaving unsafe hidden dangers and affecting the sound quality of the audio system. In the future, the second modification will cost money twice, so it will not be counted.
1. Audio equipment collocation
The first link of car audio modification – equipment matching, if the matching is unreasonable, no matter how good the installation process is, it is useless. Therefore, we need to match a reasonable sound modification plan according to the actual situation, and give the car owner a satisfactory answer.
The quality of audio equipment is also very important. No-name machines are inferior in terms of raw materials, performance, craftsmanship, and parameter indicators. Some equipment will spontaneously ignite due to substandard design and components, just like installing a time bomb that will detonate at any time. Therefore, we must have a guaranteed and quality brand for installation, and we cannot choose blindly.
2. Wire selection
The wire is an important link in the audio system, and its quality directly affects the sound quality and quality of the audio.
Cables can be divided into: signal cables, power cables, speaker cables, and optical fiber audio cables. The four types of cables are best made of high-oxidation-resistant and high-conductivity cables, and the sheaths are made of PVC, PE, PP, or POF.
3. Insurance
The importance of installing insurance is to protect the circuit when the circuit current is abnormal and exceeds its rated current. If the power supply insurance is not installed, a time bomb is also installed. If the car is moving, if the power cord sheath is worn out or the vehicle collides to cause a short circuit to the body, a fire will occur. A waterproof gold-plated insurance seat should be used to prevent short circuit and oxidation corrosion.
Fourth, process installation
The installation of car audio technology should also pay attention to two aspects. One is that the line wiring should be reasonable, including that the wiring position should not affect the original lines on the car, and prevent the lines from being broken and cut; It should be in harmony with the color of the overall layout of the original car.
5. Line layout
The design of the sound system should be reasonable, and the wiring should avoid the computer and control system, including the arrangement of power supply, signal line direction and speaker wire. The wire diameter and wiring position should be reasonable. It will interfere with the audio system, and the audio circuit will also interfere with the electrical appliances in the car. When choosing a power contact, be sure to choose the main line or battery.
When installing the main unit, speaker, processor, power amplifier, subwoofer and other equipment, each item has technical requirements, such as: speaker phase, front and rear, left and right, crossover point selection, etc. Whether the subwoofer cabinet design and construction, crossover matching combination, and frequency response combination are reasonable.
Reasonable matching, good installation technology and workmanship will make the overall performance of the audio system excellent. However, after modification, the radio effect is not good, and there may be sound field misalignment and phase error. These must be corrected during the tuning process, otherwise the effect will be directly affected. Finally, it is necessary to carry out high-standard debugging on the sound system, and to have a full understanding of the music art, so that the original sound of the music can be restored as perfect as possible, volume balance positioning processing, signal balance adjustment, working point adjustment processing, peak distortion adjustment, distance position Processing, tone adjustment, etc., in order to exert the maximum potential of the equipment, so that the selected equipment can achieve the best effect.
