18 overbearing is a new model launched by the Toyota Land Cruiser series. It not only inherited the superior off-road capability and dynamic performance of the series, but also made a new design for the appearance, making the vehicle look more consistent The aesthetic needs of mainstream consumers. This also makes it gradually become one of the favorite models of off-road enthusiasts. Modified models - 18 overbearing [Analysis of the original car audio system] The owner of this 18 overbearing car has high requirements for the comfort of the car. For the owner, the original car's sound insulation and sound effects are very general, and it is difficult to meet their own needs. Therefore, the owner of the car just put the car from the 4S shop to come up soon, they directly came to Changzhou seven car workshop, to the car made modifications and sound insulation upgrades. System Configuration: Audio source: original car host Front Sound Field Speaker: Front Door Morley Sea Belle Three-Way Speaker Rear sound field horn: Ma charm sound coaxial horn Amplifier: Dancer Gangsuo AS100.4 Amplifier DSP: German Phoenix DSP The use of audio equipment debut Front door Morley Sea Belli 3-way speaker The noise type of a car is mainly divided into two types: external noise and its own resonance noise. In order to reduce the introduction of external noise such as wind noise, the conversion technicians at Changzhou Seven-Car workshop used Russian STP sound-insulating materials to do double-layer soundproofing on the door of the car, which caused the door to form a sealed body, thereby reducing the The introduction of wind noise. Open the car door panel, you can find the door panel sound insulation measures are very lacking Use Russian STP soundproofing material to do the first layer of anti-vibration treatment to the door The chassis and tail box are the hardest hit areas for low-frequency resonance. Therefore, the conversion technicians of Changzhou Qiqifang used Russian STP soundproofing materials to do double-layer sound insulation treatment on the chassis and tail box, which not only reduced the resonance noise of the chassis and tail box. At the same time, it also effectively enhances the rigidity of sheet metal. The original car chassis and trunk are not treated with any sound insulation Use Russian STP to do the first layer of vibration damping on the chassis The second layer of the chassis is sealed with Russian STP insulation Chassis soundproofing The owners like to listen to vocal sounds, so Changzhou Qichangfang's conversion technicians replaced the car's front sound field horn with a three-way horn made by Morai Haibili. It uses a highly efficient hybrid magnetic system. And has a unique vocal restoration technology, so the music played out is truly detailed and clear. And it is very good at restoring the vocal part. The Ma charm sound coaxial horn used in the rear sound field is complementary to the front sound field horn, which makes the music more abundant. Front door Murray Sea Belle three-way bass horn installed in the car in situ Ma charm sound coaxial speaker mounted on the rear door panel In order to ensure the purity of the audio source, the conversion technicians of Changzhou Qichangfang added a German audio processor for the car's host, which can filter the noise and phase loss generated by the host to make the source cleaner. . In order to ensure that the power output of the sound field horn is stable, the conversion technician is a car audio system, and has added an official AS100.4 power amplifier. Dance Shi Gangrou AS100.4 power amplifier [Modification Effect Comments] After the upgrade is completed, the owner has deliberately selected a few vocal audition music effects, the car out of the real sense of music is very strong, it makes people feel that the singer is singing in the opposite, so that listeners can not help but with the singer Resonate. This kind of music effect can be comparable to a professional home audio system. Ford Sharp is a mid-size crossover SUV model built on the Ford CD3 platform. Like the Ford EUCD platform, the CD3 platform belongs to Ford's global mid-range sedan platform, with pre-precursors and four-wheel drive. With the increase in the time the car owner spends in the car, the demand for car audio is also increasing. As a car audio enthusiast, it is not limited to the original car audio. Soundproofing is the basis of car audio. To make a soundproof door, not only can strengthen the thickness of the door sheet metal, weaken the resonance of sheet metal when the car is running, reduce the wind noise, but also make the door plate form a closed box, which is beneficial to the speaker sound quality. The promotion. The front sound field Morley Extreme Treble and Alto inverted mold installed on the A column After the sound field Morley treble treble is installed on the door panel The front sound field installation of the Morley Extreme Three-way Extreme series is made by Morley's many mobile audio systems. It is an irresistible installation of musical LF units. After the installation of the sound field Mo Lei Yilei two-frequency buds flagship version of the series showed the best fixed-point coaxial sound and clear, rich interpretation of the tone, compared to any time the music is more dynamic than the installation of low-frequency unit renderings Power amplifier installation samurai rigid AS200.4, samurai rigid AS100.4 push forward sound field bass, midrange by AS200.4. AS100.4 push forward sound field treble and back sound field Host installation Alpine 148 Finally, the final effect of the tuning horn is not only important in tuning the brand and installation technology of the horn. Passat original car three-way system, compared to the same price of the car, the original car sound effect is OK. But this is only relatively speaking, in the face of car owners who love music, the original car audio effects still need to be improved. After a simple understanding of Israel’s Morey’s three-way speakers through the Internet, owners who like to listen to lyrical music are interested in this horn. After listening to Israel's Morey's three-way loudspeaker, the owner decided to upgrade the car stereo. The three-segment whole audio effect of the bud is very good, the treble is extremely clear and natural, the midrange is mellow and sweet, and the bass is full of mellowness. It should be noted that the Inteli three-way kit speaker is very demanding on the power amplifier, and the ordinary amplifier is difficult to achieve the best results, while the NVS AS100.2 power amplifier can achieve this. Volkswagen Passat audio conversion configuration: Host: Alpine A08 CD Before the sound field: Israel Moray buds three-way flagship version After the sound field: Moore Ma Shiwu coaxial horn Amplifier one: Italy Wu Shi soft AS100.2 Amplifier II: Alpine Power Amplifier Capacitance: Lai Fuk 1 Farah capacitance Ultra Bass: Morley Dance 12 inch subwoofer After the equipment is installed, perform acoustic debugging. After repeated debugging, excellent craftsmanship and sound quality expression, you can interpret popular music, DJ, folk music and even symphony incisively and vividly, outputting near-perfect sound quality, and the system can obtain the best sound effects.
