Precautions for car audio modification
1. Sound insulation engineering must be done
In order to reduce the weight and cost of the car, the automobile the manufacturer has made the body iron shell thickness of 0.6mm, the iron sheet is extremely thin, and the original vehicle sound insulation material is also pasted with a small sound insulation board on the large area iron plate, which can not get up. The great sound insulation effect causes a resonant sound wave in the driving vibration of the car, and the noise can reach 75dB-100dB or more during driving. Therefore, to modify the audio, the sound insulation project must be done first, otherwise, the modification effect will be seriously affected.
The special material for the modified sound insulation system has high thermal insulation performance, super adhesion, anti-aging, anti-static performance, which greatly optimizes the environment in the car and makes you drive more quietly.
2. Pay attention to the use of wire and line layout
High-fidelity audiovisual cables for automobiles deliver pure sound quality and guarantee excellent quality. All horns are installed in the original car horn position, there is no need to destroy the original car structure, including the independent installation system of the circuit, which has no effect on the original car circuit. The circuit is carefully protected by professional technicians. The main circuit will also have installed fuse( Fuse) protection, there is no safety hazard, the installation of the horn will also undergo waterproof and shockproof treatment. The installation position of the power amplifier is usually at the bottom of the seat or the trunk, and will not affect the functional structure of the car. The subwoofer is installed in the trunk and fixed flexibly.
3. Pay attention to the matching of the power amplifier and speaker
The original car audio currently equipped is generally an ordinary four-channel single-disc CD host without audio output and two additional pairs of speakers with relatively small carrying power. The sound effect is average, and some are even very muddy and dim. The distortion is more serious after the volume is halfway through. . In view of this situation, the simpler upgrade method is front sound field speaker + three-way or four-way power amplifier + 10-inch subwoofer. The main sound field speaker and the subwoofer must be considered together when choosing. It is best that the two styles are the same. For example, if the main sound field speaker chooses to listen to vocal instruments, then your subwoofer should also be softer, otherwise the harder one. The subwoofer is difficult to harmonize with the mid-bass of the main sound field.
Precautions for car audio modification
When choosing a power amplifier, one must consider the matching of music style and the other must consider the matching of power and impedance. The matching of music style means that if your speakers are good at performing warmer vocal effects, then you must choose to match the same style of the power amplifier; if the speakers are good at performing cold heavy metal effects, then the style of the power amplifier should also match The same. The power matching means that the power amplifier must push the speaker to work in a natural state, and the impedance matching means that the impedance of the power amplifier and the impedance of the speaker must be the same.
