濟南汽車隔音http://www.szanyuda.com/介紹一個完整的音響系統，線材是不可或缺的組合部件，但線材卻往往容易被忽視。其實線材的好與壞，會直接影響聲音的品質，因為線材從材質、絞合結構，到直徑、絕緣與阻抗值等設計與規格上的不同，都會影響訊號或電量的傳送。而在線材的使用方面，會因不同的器材需要有不同設計取向的線材，如電源、接地、啟動、訊號、喇叭、光纖與特殊系統所需的線材，都因各自要求不同而在設計上有所區別。
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.

濟南汽車隔音http://www.szanyuda.com/分析汽車音響大多為前后級合一市售的主機之中，已經具備了音源、前級和后級，囊括了音響構成的基本結構。汽車音響主機中，是不是可以調整音量的大小，而且即使是最低檔的主機也有高音與低音的音色調整，那就是有前級了。此外，如果汽車音響系統中，是以主機直接去推喇叭的話，那必定是主機中內含了功率擴大器，例如普通的原廠主機或是大多數的改裝主機都會有功率輸出。而有一種主機沒有附內置功率擴大器輸出的，這種主機一般俗稱為啞巴機，僅有訊號輸出而已。不要以為這種主機會較便宜，其實大多數啞巴機都屬于最高級的旗艦級，因為會使用啞巴機的音響必定會安裝功放，因此主機內部零件的用料更加高級，線路架構的走法更為完整，所以價格也是最貴的。
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.
