济南汽车隔音http://www.sdcarmusic.com/介绍一个完整的音响系统，线材是不可或缺的组合部件，但线材却往往容易被忽视。其实线材的好与坏，会直接影响声音的品质，因为线材从材质、绞合结构，到直径、绝缘与阻抗值等设计与规格上的不同，都会影响讯号或电量的传送。而在线材的使用方面，会因不同的器材需要有不同设计取向的线材，如电源、接地、启动、讯号、喇叭、光纤与特殊系统所需的线材，都因各自要求不同而在设计上有所区别。
Jinan car noise introduced an integrated sound system, the wire is indispensable combination of components, but the wire is often easily overlooked. In fact, the wire is good or bad, will directly affect the quality of the sound,because the material is transferred from the wire, twisted structure, the different signal or power will affect the design and specification of the diameter of the insulation resistance value and so on. The use of the wire will vary depending on the equipment needs to have a different design approach of wire, such as power, ground start, signals, horn, fiber and a special system for the wire, both because of their different requirements and design has the difference.

济南汽车隔音http://www.sdcarmusic.com/分析汽车音响大多为前后级合一市售的主机之中，已经具备了音源、前级和后级，囊括了音响构成的基本结构。汽车音响主机中，是不是可以调整音量的大小，而且即使是最低档的主机也有高音与低音的音色调整，那就是有前级了。此外，如果汽车音响系统中，是以主机直接去推喇叭的话，那必定是主机中内含了功率扩大器，例如普通的原厂主机或是大多数的改装主机都会有功率输出。而有一种主机没有附内置功率扩大器输出的，这种主机一般俗称为哑巴机，仅有讯号输出而已。不要以为这种主机会较便宜，其实大多数哑巴机都属于最高级的旗舰级，因为会使用哑巴机的音响必定会安装功放，因此主机内部零件的用料更加高级，线路架构的走法更为完整，所以价格也是最贵的。
Jinan car audio car sound analysis mostly among commercially available before and after class one host, has had the source, before and after stage, covering the basic structure of sound composition. Car audio host, is not able to adjust the size of the volume, but even the most low-end hosts also have to adjust the treble and bass tone that former grade. In addition, if the car audio system, is host to push the speaker directly, then it must be embedded in a host of power amplifiers, such as the original host or the most common modification hosts will have a power output. And there is a host is not attached to the built-in power amplifier output, which is generally known as the dumb host machine,the only signal output only. Do not think that this would be cheaper hosts, in fact most of the dumb machines are among the most advanced flagship, because it will use sound dumb machine will certainly install the amplifier, so the internal parts of the host material is more advanced, the line moves more architecture to complete, so the price is also the most expensive.
