Monsters should hear more, car audio can be heard monster? As the name suggests this is a relatively large sound system, following is my modified Nissan Sunny car audio system of the other fanatical type of sound masterpiece, especially promotion to the general car audio enthusiasts. He said the Sound \"monster\"? Here\\ s the answer: The system total power of more than 3000W, six power amplifier, 10 \"subwoofer 8, 6.5\" woofer 4 pair, 5 \", 4\" component speaker set for each, a total of 24 speakers, 100AH ??battery 3 a, 1 crossover sets, CD players, a 15 farad capacitor an … … on all of these devices installed in a Cherokee jeep, incredible, right? Sound pressure level of the system to maximize the goal of filling the wild, assertive personality, so strong is the power output capability of the amplifier and speakers I chose the primary factor, the United States to blessing is a good choice.
Powerful electronic crossover
CD player is a blessing to the higher grade RFX-8340 single-disc machine, which is located 3 Group 4 volt RCA output, but thanks to EPX2 electronic crossover, so it is only the first sound field (FRONT) output. The entire system with up to 6 amplifiers, signal distribution, crossover setting is a big problem. Fortunately, to the blessing of \"small supernatural\" computer crossover EPX2 set crossover, equalizer in one, there are two different signal input options, up to seven groups of signal output, crossover can be adjusted, and built with pink noise, 28 E28 balanced card, much easier to deal with them. EPX2 can store 16 groups of good frequency tuning curve, and three groups of different pre-set volume of the best results when the frequency curve, according to the size of the volume frequency curve in the three groups automatically switch to get the best replay the effect.
The amplifier is used to blessing the highest grade bd series and POWER series, speaker series is to match with FNX and the form of a 4-frequency, in order to enormous pressure in the case of voice to maintain sufficient clarity. Before the sound field using a 4 \"FNX-2414 set as the replay 275Hz-20KHz alt task. In line with the back of eight of the total power of 4000W subwoofer, ensure a good front sound field, the first sound field used four pairs of 6.5 \"and FNX-2406 unit, responsible for the replay 80Hz-275Hz low-frequency, after the frequency of the sound field in the design of the next two points with a 5.25\" and FNX-2514 speaker package to ensure that the brightness of the sound and can get a larger power capacity in the power amplifier with on, with the two series of four-channel POWER 400.4, a replay is responsible for the high-frequency, used to promote before and after the sound field of 4 \"and 5\" component speaker; another is responsible for the low audio playback, push the front sound field for the four pairs of 6.5 \"woofer. Connection to push two per channel in parallel FNP2406. POWER400.4 Europe in the case of load 2 can output 100W * 4 power to meet the rated power of 70W of FNX2406 more than enough.
Low-frequency reproduction
Woofer with a 500W RMS power with 8 dual 2Ω voice coils RFD2110, replay 20Hz-80Hz is responsible for the ultra-low frequency. 8 woofer is divided into four groups, each 2 by 1 500bd single amplifier to push, sharing a four 500bd, 500bd in the case of 2 ohm load 600W RMS power output, so you can make the amplifier and speakers to achieve the best power, impedance matching, so that they work in an ideal state. Since the total power system too, in no way replace the generator in the case, in the original installation of the power system based on three 100AH ??battery and a 15 farad capacitor.
Built a large change, construction noise
From the start the moment, open sound, it took a month audition time (due to the speakers, all the car door handle paint, the surface finish is very high, time-consuming). For filling the wild character, individuality, inside the color to yellow, black, and from the instrument panel to the leather seats, speakers, door fully and completely implement this style, dazzling bright yellow with contrasting black with the maximum to attract people\\ s attention.
Noise damping measures is an important part of installing one, in order to minimize the vibration and reduce sound power of losses and the resulting harmonic adverse impact on the quality, the need for the door and around the thin, easy to vibration the site for noise processing. Because each of the front doors to be installed four 6.5 \"woofer FNX-2406 in order to ensure the doors have sufficient strength, especially the original door trim abandoned in favor of 12mm MDF to be modified. FNX2414 front sound field Set speaker mounted on both sides of the foot position to enable the tweeter as farther away from the ears, in order to get a deep, wide sound field, while the shift lever next to the word order of the four bass control knob for the bass the regulation provides maximum flexibility.
As the equipment too narrow to be in the trunk good and show them all placed people to see, it is really difficult. 8 10 \"subwoofer in two rows side by side, towards the front (this arrangement for the pursuit of maximum efficiency in terms of sound pressure level). Subwoofer draws to shape the image of blessing\" mechanical wolf \"design approach, through two only \"navy blue Langyan\" bass box woofer can see the \"ass.\" subwoofer to make the \"face\" exposed to, we put the original car\\ s back seat removed, fitted with a simple stainless steel back .
As the horizontal space, power amplifier can only be used to install the ladder-shaped design of the development of upward way, each amplifier base is a 12mm thick glass, at night, navy blue spotlights projected through the glass the light is moving.
Audition date
Fighting a month, and finally assembled. After all the speakers for the phase correction unit, high, medium, low balance adjustment, then boil for 30 minutes. Eagle band \"Hotel California\" was a prelude to full flexibility, deep drums sounded powerful, crisp performance, there is no clear-cut.
Replay \"A Jiegu\" bass, faint low-frequency slowly flooding back from a distance, filled every crevice inside, plenty of power that make sense until you realize the feeling of the earth was moving, the mind is completely shocked. The \"Para2 Rave\" dance, as if closely linked to the powerful bass pulse, the heart is beating with the rhythm of it. I then increase the volume increase, the hair will soon put up. Useless sound pressure level measurement, but the experience and feel point of view, sound pressure level should reach 150db. Or the coat off it, too hot.
Put \"Folk Song Tsai,\" the first song, \"Forgotten Time\" and the eighth song \"Ferry\", high definition sound, structured, just feeling a little tight, there is no kind of relaxed Tsai, his right The tone and look. However, the pursuit of a sound pressure of the system is already very good.
The sound field effect is concerned, even if behind the 8 subwoofer, the driving position to hear the music or from the front, there is a strong presence, and broad sense of good feeling of depth. Only because of much higher jeep seat design, feeling a little low rising tone a little field.
This is a super-car audio enthusiast for the health of the Super Car audio System.
