2改装禁忌编辑

汽车音响改装1、占小便宜心理据统计，一般改装音响的的费用大约在1000~7000元不等。那么在谈到改装汽车音响时，有很多车主坦言自己并不是准专业级的音响发烧友，因此只希望花一点小钱来改善一下音乐环境和音乐乐感就可以了。于是在选择汽车音响改装店时往往“什么便宜选什么”，把“一分价格一分货”的道理忘得干干净净，导致最终对改装效果

2、对所选汽车改装店专业性的错误估计音响改装首先需要注意的就是电路问题，在对汽车音响进行改装和维修时一定要到具有专业经验的汽车音响改装店，因为，不专业的改装店很可能在改装过程中破坏原车电路，这样不但音响效果没有得到改善，还有可能会影响到车辆保修及一系列的售后服务问题，在布线时，一定要做到单独布电源线、音频线、信号线，而且线路之间做好屏蔽与保护，做到万无一失。但是对于车主来说，是很难正确判断出一家汽车改装店是否专业的。最好的办法提前查看对各地汽车改装店的推荐与评估，做到心里有数省去不必要的麻烦。

3、忽略音响改装的升级空间据了解，很多车主在对汽车音响进行改装时，常常忽略了日后的升级空间。改装音响一般有着循序渐进的过程，大致的顺序是先换喇叭，然后升级功效，再增加低音喇叭，最后更换主机。但是车主们最好是能够预留一些升级空间，日后如若要升级解析力强的主机，就能达到HIFI的音质效果了。如果不预估日后升级空间，待到有升级需求时就会遭遇升级瓶颈。

4,当人们判断一个专业音响好的和坏的音响系统，无论是频率响应作为评价的主要目标曲线的平滑度。例如，无论是高山汽车音响主机，功放和扬声器具有非常平滑的频率响应曲线。其中DDDrive系列音箱大阿尔派可以提供线性，低音回放效果，而不是在低一些发言者盲目装修及重公正。

3最佳效果编辑

汽车音响改装想提高车载音响系统的音质？先从音源下手。在建立音响系统时，各个器材的搭配应当保持风格基本一致，否则可能造成外观、功能、使用、指标等方面的不协调。

●要CD、MD，不要VCD、MP3

如果只用来播放声音，主机还是选择CD、MD或DVD。VCD的音质较差，最好不用；MP3属于压缩格式，虽然增加了音质处理电路，但音质仍不如CD；DVD的音质接近CD，但整体比较，仍不如CD；MD的音质与CD相差不大，但声音稍微有些硬。

●要”原汁原味”，不要均衡器

主机应选用对信号无任何修饰的机型，即所说的“原汁原味”。信号经过修饰后，其波形产生畸变，所以播放出来的音乐不理想。

“原汁原味”的主机最好没有图示均衡器、 场效（如剧场、广场、播音室等）。对场效进行修饰后，原有的信号会产生变化，失去了原来的音质。

●要24bit，不要1bit

选择机型要看频响指标，不带任何附加修饰音质的功能。20bit和24bit高解析力才能使音乐得到充分展现。普通音响多为1bit。

●要大功率，不要失真

如果用主机直接推动扬声器，要选择输出功率高的。主机输出功率一般在4×50W，主要是降低失真。

如果用主机的前置输出，要选择输出电平高的，目的是为了提高信噪比，输出电平一般在2V，最好选择4V输出。顺便说一下，CD唱片要选用正品，用盘面上印有“DDD”的最好，这种CD唱片制作出来的音质好。

4如何配置编辑

汽车音响改装挑选真正的车用好音响需要严格把关在购买汽车音响或其它的汽车电子商品时，大部分消费者第一个考虑的因素多半是预算，不过要注意的是，价格和商品的功能、特性是绝对相关的，考虑的时候更要先想清楚，自己的需求是什么，这样挑选才有意义。

消费者如果注意一下，就会发现功能差不多的音响，车内使用的常常会比家用的贵，原因是所有在车上使用的设备基本上要能够耐高温、耐震动，因而规格上的要求都较严格。同时最重要的是，车内设备的使用对行车的干扰要能降到最低，切不可喧宾夺主，为了操作设备而影响行车安全。

汽车音响既然是音响的一种，属于音响选购的要点大致上是差不多的，是看个人对音质、音色的要求。这里特别要提的是因为在车内使用而产生的差异点。

车用音响要注重安全

首先是前面所提的安全考虑，要考虑商品的操作是否都在就手的地方，是否都易学、易记，有没有针对行车安全的特别设计。例如有些汽车音响主机可以搭配一种叫做安全杆控的控制杆，设计的原理是将音响控制主要功能集中在一个控制杆上，透过用手触摸就能进行各项操作，像是在控制雨刷、车灯等，完全不必分神用眼睛看。

其次，车内这样的聆听环境和家里大不相同，除了前述的高温、震动之外，还会有四面八方涌来的噪音，这些噪音会干扰音乐的低频带，一般是加装扩大机来克服这个问题。扩大机要依据整个音响系统的规模?喇叭数、喇叭尺寸及频率响应等?考虑声道数及输出功率。输出超过扩大机的最大输出功率时，可能会导致扩大机烧坏。如此看来，是否输出功率越大越好呢？其实车子里面空间不如家里那么大，不必迷信大功率输出，只要够用就可以了。此外，输出功率愈高，价格也会随之上升。

5隔音步骤编辑

汽车音响改装具体来讲，系统的隔音工程一般经过减震、降噪、密封三个步骤完成。

　　首先，对四个车门、后备箱、车地板、引擎仓及车顶进行减震处理； 　实施减震处理时，有主次之分：首先是车门和后备箱，因为绝大部分噪音是通过汽车的悬挂系统、后备箱、底盘、车门等部位传入车内的；其次是车地板和引擎仓；最后是车顶。

　　最后，对车内进行密封处理。

　　对车内进行密封处理时，不要过度密封，因为车体密封工程是解决由外向内传播噪音的基础工程，应做到车体良好密封，使车内气压保持平衡，否则，过度密封能造成车内缺氧，给您的身体带来危险。

　　由于车内噪音不易集中治理，因此，对施工产品的质量和施工技术有较高的要求，一般情况下，专业的声学产品属较好的隔音产品，这包括隔音垫和吸音棉两种材料，隔音垫粘贴在车体产生振动的部位，而吸音棉能吸收减震胶对付不了的杂振产生的噪音。通常情况下，实施汽车隔音工程时，需贴一层隔音垫和一层吸音棉。

　　一般的隔音工程施工后，能使噪音降2-3分贝，好的材料能使车内噪音降5-8分贝，最好的情况下，能降13分贝，如果施工人员告诉您能降20分贝，甚至更多，那您就该注意是不是被忽悠了。

　　另外，只做挡火墙是达不到较好的隔音目的的。

6汽车隔音编辑

汽车音响改装汽车隔音产品源于20世纪80年代末由美国一群汽车音响发烧友为了能够更好的享受到汽车音响所带来的乐趣而开发的，这些产品既是可以降低行驶过程中车内的噪音，又可以提升汽车音响的音压和音色。所以说汽车隔音原本是为真正热爱汽车的享乐主义者而创立，目的是让更多车主的生活得到完美的升华享受更美妙的驾驶乐趣。如果在汽车音响改装之后不注意隔音，那么车主的享受可能会给路人带来很大的困扰。

7五大误区编辑

汽车音响改装消费者决定购买某个产品的动因取决于三个要素，一是品质，二是价格，三是品牌。汽车音响改装的好与坏、优与劣，除了产品的品质、价格、品牌因素外，还要注重改装技术。但有些车主不太明白，而音响改装店也不加以正确引导，有些店家反而误导，因此需要加以警惕。

误区一

以非常炫的产品外观和包装吸引车主消费者的注意力。比如我见到过一款车载功放，包装搞的很夸张。木盒外包皮革，打开后盒内衬猩红色丝绒，映入眼帘的一个制作、印刷精美的长方形类似饼干铁盒，打开后，看到的确是置放在功放上的一双高支针织雪白手套，下面才是用蓝色丝绒布袋装着的功放。这样的包装，让人感觉产品非常高档。厂家在产品上下了如此功夫，无非是制造噱头，博个车主消费者的第一印象，价格自然不菲，然而品质呢······

误区二

价格成为衡量汽车音响品质的尺度，存在两种极端，一是过分追求高价产品，认为选越贵的越好，有道是贵有贵的道理;另一种则是，越便宜越好，认为音响改装无非就是换个机头、喇叭，所选换装品越便宜越好。其实，这两种想法都是虚荣心作怪。前者逢人便会炫耀，我改装汽车音响，花了多少钱，档次很高;后者逢人问起就会说，我的车做了汽车音响改装，显得有品位。

误区三

洋品牌情结挥之不去。因为平时消费商品有洋品牌情结，故车改音响时不懂装懂，认为洋品牌一定就比国产品牌好。国产品牌也有优秀的产品，很多国外的知名品牌被中国的小厂利用其品牌作假。所以在鱼龙混杂的市场中挑选产品时最重要的就是试听。每个人对音乐的理解都不一样，只有试听才能确定喇叭是否符合你的听感。

误区四

功率越大越好，装一个大口径低音炮和驱动功放是实现低音效果的外在原动力。殊不知，在中低音喇叭品质不好，驱动功放品质低劣的情况下，失真的低音反而会变成噪音。如此“炸机”当做低音反映了人心浮躁的一个方面，再说了，天天坐在车里“炸”，你的耳朵能够受得了这样的折磨吗?其实，随着年龄增长，人的心态会变得愈发平和，听的最多的可能还是轻音乐或人声演唱。

误区五

不注重改装技术，有道是七分器材、三分技术。汽车音响不同于家用音响，买回家接上线就OK了。再好的主机、喇叭、功放没有好的改装技术用优良的辅材进行匹配、安装、调试、再调试(新的器材改装完毕一定要煲一段时间再回到店里重新调试)，等于事倍功半，应有的音响品质没有发挥出来是不是很郁闷啊?

例举了以上汽车音响改装的误区种种，就是想说明，汽车音响改装也是器材、技术、艺术修养的完美结合。能够把它们合理地整合起来，像一幅完整美丽的画卷，像一个完整的舞台，展现在你的面前，哪才是一种真正的享受，才能达到物有所值。汽车音改，虚荣心要不得，品质是硬道理。

无论厂家还是改装店，在汽车音响改装市场当中应当负有正确引导责任，而不是误导车主消费者，如此，汽车音响改装市场才能健康发展。

Change his costume or dress above all car acoustics needs to notice most is -- the music that you like what style after all! Well-known, showing it may be said of happy like modern pronunciation of Chinese characters style is to let a hundred flowers blossom, what rocks and roll, happy, vocal music, voice waits DJ, popularity a moment to have a lot of sufferring numerous crowd.

2 change one's costume or dress no-no editor

Car acoustics changes his costume or dress 1, occupy petty gain psychology to occupy statistic, change his costume or dress commonly of acoustics charge is in about 1000~7000 yuan differ. So in speak of change one's costume or dress when car acoustics, have a lot of cars advocate say frankly the acoustics that oneself are not standard professional form has a fever friendly, because this hope spends a bit penny,will improve music environment and phonic Le Le feel OK. In the choice then car acoustics changes his costume or dress when inn often " what petty gain chooses what " , " a minute of price a minute of goods " the truth forgets neatly, bring about be opposite finally change one's costume or dress the effect

2, what to what choosing a car to change one's costume or dress the mistake with professional inn reckons acoustics changes his costume or dress to need to notice above all is circuit problem, must arrive when undertaking change one's costume or dress and be maintaininged to car acoustics the car sound that has professional experience changes his costume or dress inn, because, not professional change one's costume or dress inn is changing his costume or dress probably primary vehicle circuit is destroyed in the process, such not only acoustics did not get ameliorative, influence of possible still meeting guarantees to car reach a series of after service problem, when wiring, must accomplish line of alone cloth power supply cord, frequency, line, and good screen and protection are done between circuit, accomplish no risk at all. But to the car advocate for, it is very difficult correct judgement gives a car to change one's costume or dress whether inn is professional. Best method examines pair of each district cars to change one's costume or dress ahead of schedule the commendation of inn and evaluate, accomplish the trouble with needless leave out of the know exactly about sth in the heart.

3, oversight acoustics changes his costume or dress upgrade space as we have learned, a lot of cars advocate when undertaking changing one's costume or dress to car acoustics, often oversight in the future upgrade space. Change one's costume or dress the process that acoustics is having successive commonly, roughly is to change a horn first orderly, upgrade next effect, increase sackbut again, change finally lead plane. But car advocate people had better be can obligate a few upgrade space, if want,upgrade in the future the leader with analytic powerful force, can achieve the acoustic quality result of HIFI. If not beforehand appraise upgrades in the future space, wait for have upgrade bottleneck upgrades with respect to meeting experience when demand.

4, judge a professional euphonious and bad sound system when people, no matter be frequency,answer the smoothness of the main goal curve that serves as an evaluation. For example, no matter be lead plane of acoustics of high mountain car, result put He Yangsheng appliance to very flowing frequency answers a curve. Among them clique of Er of big A of DDDrive series sound box can offer linear, bass is answered put the result, is not to be in a few lower the person that make a speech is decorated blindly reach heavy justice.

3 optimal effects edit

Does car acoustics change his costume or dress the acoustic quality that wants to raise a car to hold sound system? Do it from phonic source first. When building sound system, the collocation of each equipment ought to maintain a style to agree basically, may cause the exterior, function otherwise, use, do not coordinate of the respect such as index.

● wants CD, MD, do not want VCD, MP3

If be used only,broadcast voice, lead plane still chooses CD, MD or DVD. The acoustic quality of VCD is poorer, had better not use; MP3 is belonged to compress a format, although increased acoustic quality to handle circuit, but acoustic quality still is inferior to CD; The acoustic quality of DVD is close to CD, but whole is compared, still be inferior to CD; The acoustic quality of MD and CD differ not quite, but sound has a little some hard.

● wants " former juice raw ingredient " , do not want equalizer

Lead plane should choose the model that does not have any decorating to signal, what say namely " former juice raw ingredient " . After signal course is decorated, its weaveform produces distortion, broadcast the music that come out so not ideal.

"Former juice raw ingredient " lead plane had better do not have effect of graphic representation equalizer, field (wait like theater, square, studio) . After undertaking got-up to field effect, original signal can produce change, lost original acoustic quality.

● wants 24bit, do not want 1bit

Choice type should view frequency noisy index, do not take the function of any add got-up acoustic quality. 20bit and 24bit are tall analytic power ability makes music gets be showinged adequately. Common acoustics is 1bit more.

● wants high-power, not lack fidelity

If use lead plane to drive loudhailer directly, should choose to output power tall. Power of lead plane output is in commonly 4 × 50W, basically be to reduce lack fidelity.

If use lead plane before buy output, should choose to output n tall, the purpose is to raise letter a confusion of voices to compare, output n is in commonly 2V, best choice 4V is outputted. By the way one, CD disc should choose quality goods, use dish of face to go up imprint have " DDD " best, the acoustic quality that disc of this kind of CD makes is good.

4 how to configure an editor

Car acoustics changes his costume or dress choose right vehicle to need to guard a pass strictly with nice sound when the car electron goods that buying car acoustics or other, the element most that major customer considers the first times is a budget, what want an attention nevertheless is, the function of the price and commodity, character is absolutely and relevant, when considering, should want to be clear about first more, what is oneself demand, choose gift so significant.

If consumer notices, with respect to the acoustics that can discover the function is about the same, what the constant regular meeting that uses inside the car compares family expenses is expensive, the reason is all device that use on board basically want can high temperature resistant, be able to bear or endure shake, the requirement on norms is consequently stricter. At the same time the most important is, the use of the equipment inside the car wants to be able to fall to the interference of drive a vehicle lowest, must not a presumptuous guest usurps the host's role, affect safety of drive a vehicle to operate facility.

Since car acoustics is a kind of acoustics, the point haply that belongs to acoustics choose and buy is about the same, it is to see an individual be opposite acoustic quality, tonal requirement. Because inside the car the difference that use and arises is nodded,what should carry particularly here is.

The car should pay attention to safety with acoustics

It is above all in front the safe consideration that mentions, whether is the operation that should consider goods the place of while you're at it, whether to learn easily, write down easily, be aimed at the special design of safety of drive a vehicle. It is OK to have some of car acoustics leader for example the control lever that collocation is called safe lever one kind to accuse, the principle of the design is acoustics control main function is centralized on lever of a control, pass through the feeling that use a hand to be able to have each operation, resembling is to controlling rain to brush, light, complete need not give a little attention to looks with the eye.

Next, in such listen respectfully environment inside the car and home very different, besides aforementioned high temperature, shake besides, return the noise that can far and near emerges, these noise can disturb small frequency band of music, it is to add commonly outfit expand machine will overcome this problem. Enlarge confidential basis the dimensions of whole sound system? Are dimension of horn number, horn and frequency answered etc? Consider acoustical number of channels and output power. When output enlarges the power of the biggest output of machine more than, may bring about expand machine is burned-out. Look so, whether to output power to had been jumped over greatly more? Actually the space is inferior to the home inside the car in so big, need not have blind faith in high-power output, it is OK to should be used quite only. In addition, output power heals tall, the price also can rise subsequently.

Measure of 5 sound insulation edits

Car acoustics changes apparel body to tell, sound insulation project of the system passes damping commonly, fall a confusion of voices, sealed 3 measure are finished.

Above all, undertake to storehouse of floor of 4 door, mothball box, car, engine and roof damping is handled; When executive damping is handled, have the branch of primary and secondary: It is door and mothball box above all, because majority noise is the place such as the pensile system that adopts a car, mothball box, batholith, door,pass into a car inside; It is car floor and engine storehouse next; Finally is roof.

Finally, sealed to undertaking inside the car processing.

When sealed to undertaking inside the car processing, not excessive and sealed, because bodywork is sealed,the project is to solve by the fundamental project that noise transmits inside extroversion, should accomplish bodywork good and sealed, make the atmospheric pressure inside the car poises, otherwise, excessive and sealed can create a vehicle inside anoxic, the body that gives you brings risk.

Because the noise inside the car centers processing not easily, accordingly, have higher demand to the quality of construction product and construction technology, usually, professional acoustics product belongs to better sound insulation product, this includes sound insulation mat and sound-absorbing cotton two kinds of material, sound insulation mat is stickup the position that produces vibration in bodywork, and sound-absorbing what cotton can absorb damping glue not to make do is miscellaneous brace up the noise of generation. Normally the circumstance falls, when project of executive car sound insulation, need to stick a sound insulation to fill up with sound-absorbing cotton.

After construction of general sound insulation engineering, can make noise falls 2-3 decibel, good stuff can make the noise inside the car falls 5-8 decibel, below best circumstance, can fall 13 decibel, if apply work staff to tell you,can fall 20 decibel, more even, then you notice with respect to this is by flicker.

Additional, do fire-wall is the sound insulation purpose with better short of only.

6 cars sound insulation edits

Car acoustics changes his costume or dress product of car sound insulation results from 20 centuries 80 time end by the United States a flock of car acoustics have a fever friendly for can the better fun that enjoys car acoustics place to bring and of development, these product since can reduce the noise inside the car in travel process, the sound that can promote a car acoustics again controls symphonious expression. Saying car sound insulation so is originally found to have deep love for the epicurean of the car truly, the purpose is to allow more car advocate the life gets ideal raising of things to a higher level is enjoyed more wonderful drive fun. After if be in,car acoustics changes his costume or dress carelessly sound insulation, so car advocate enjoy may bring very big worry to passerby.

7 5 big errors edit

Car acoustics changes his costume or dress consumer decides those who buy a certain product to because depend on,be moved 3 element, it is character, 2 it is the price, 3 it is a brand. What car acoustics changes his costume or dress is good with bad, actor and bad, besides element of the character of the product, price, brand, pay attention to even change one's costume or dress technology. But some cars advocate not quite clear, and acoustics changes his costume or dress inn also does not try to guide correctly, some inn-keeper instead misdirect, because this needs,try vigilant.

Error one

The product exterior with special dazzle and pack attract a car advocate the attention of consumer. For instance I had seen a Che Zaigong put, pack those who do is very exaggerative. Leather is included outside wooden box, lubricious velvet of blood-red of liner of the box after opening, one of greet is made, presswork elegant rectangle is similar biscuit iron box, after opening, seeing is buy is put in really result put a pair on to raise knitting high snow-white glove, ability is to use the work that blue velvet hop-pocket is holding to put below. Such packing, product of feeling letting a person is very high-grade. Manufacturer made great efforts such on the product, no more than is production stunt, rich car advocate the first impression of consumer, price nature does not poor, however character · of · of · of · · ·

Error 2

The price makes the measure that judges car sound quality, put in two kinds of extremes, it is product of high price of beyond the mark pursuit, think to choose more expensive better, the truth; that having is Gui Yougui is another kind, jump over petty gain to had been jumped over, think acoustics changes his costume or dress no more than changes a nose, horn namely, it is cheaper to what choose transhipment of through cargo to taste better. Actually, these two kinds of idea are vanity do mischief. Former meet the person can be shown off, I change my costume or dress car acoustics, spent how many money, class is very high; latter meets the person asks about to be able to say, my car did car acoustics to change one's costume or dress, appear have grade.

Error 3

Of brandish of foreign brand complex do not go. Because consume commodity to have foreign brand complex at ordinary times, when friend car alters acoustics, do not understand outfit understand, it is good to think foreign brand compares card of home made product certainly. Card of home made product also has outstanding product, the well-known trademark of a lot of abroad is used by small plant of China its brand cheat. So the most important when the product selects in the market of good and evil people mixed up is to try listen. Everybody is different to musical understanding, try those who listen to ability to decide whether the horn accords with you to listen only feeling.

Error 4

Power has been jumped over greatly more, installing artillery piece of bass of a large requirements and drive result to put is the explicit motive power that achieves bass result. Little imagine, be in in sackbut character is bad, drive result puts the case with inferior quality, lack fidelity bass can become noise instead. Such " scamper machine " should do bass to reflect a side with blundering popular feeling, said again, sit in the car every day " scamper " , can your ear can bear such torment? Actually, grow as the age, the person's state of mind can become send more gentle, audition most possibility or light music or voice are sung.

Error 5

Do not pay attention to change one's costume or dress technology, having is 3 minutes of 7 minutes of equipment, technologies. Car acoustics is different from family expenses acoustics, redemptive home is received on line with respect to OK. Again good leader, horn, result puts those who had done not have to change one's costume or dress the technology undertakes matching with good complementary material, installation, debug, debug again (new material changes his costume or dress end must farewell of Bao period of time debugs) afresh in inn, be equal to get half the result with twice the effort, it is very depressed that due sound quality comes out without play?

Exemple the error that cited above car acoustics to change one's costume or dress a variety of, want to explain namely, car acoustics changes his costume or dress also is the perfect union of equipment, technology, artistic accomplishment. Can them reasonably conformity rises, resemble the picture scroll of a complete beauty, resemble a whole arena, be shown in you before, which ability is a kind of true enjoyment, ability achieves content to be worth somewhat. Car sound changes, vanity no good, character is good sense.

No matter manufacturer still changes his costume or dress inn, change his costume or dress in car acoustics ought to have among the market conduct duty correctly, is not misdirect car advocate consumer, such, car acoustics changes his costume or dress market ability health develops.
