1、濟(jì)南汽車音響http://www.szanyuda.com/端子主要用途在使接點(diǎn)阻抗降低、施工方便、美觀、安全，一般市面販?zhǔn)鄣亩俗訛殄冨a制品，反而會(huì)增加阻抗這并非專業(yè)，濟(jì)南汽車音響所愿意使用的，為使其接點(diǎn)更好的例如鍍金、鍍銀、鍍銠等，但鍍銀及鍍銠的成本上高出很多，所以目前還是較普遍使用鍍金端子。
Jinan car audio terminal main purpose in making contact impedance decreases, construction convenience, aesthetics, safety, general market to sell the terminal for tinned products, but will increase the impedance of this is not professional, Jinan car stereos are willing to use for making contact better example gold, silver, rhodium, etc., but much higher than the cost of silver-plated and rhodium-plated, so now is the more widespread use of gold-plated terminals.

2、濟(jì)南汽車音響保險(xiǎn)絲、保險(xiǎn)絲座其主要用途在于“保護(hù)”，一方面保護(hù)擴(kuò)大器，避免擴(kuò)大器受到超過其負(fù)荷的電壓源或電流源的影響，而造成擴(kuò)大器本身得損壞。一方面保護(hù)電源，避免電源受到人為或其它因素影響，造成短路，而產(chǎn)生電池打穿、爆裂的危險(xiǎn)。
Jinan car audio fuse, fuse holder and its main purpose is to "protect", on the one hand to protect amplifier to avoid expanding beyond its load is affected by the voltage or current source, and the resulting expansion of itself was damaged. On the one hand to protect the power supply to avoid man-made or other factors affected, causing a short circuit, and produce batteries penetrated danger of bursting.

3、濟(jì)南汽車音響接地座當(dāng)使用的器材較多時(shí)，為避免分散接地而產(chǎn)生電位差、產(chǎn)生電阻影響電源電流的通暢性，所以使用共同接地座，達(dá)到電源通暢。     
When Jinan car audio equipment grounding seat when using more, in order to avoid dispersion of a ground potential difference is generated, the impact resistance of the supply current generated patency, so the use of common ground base,to achieve power patency.

4、濟(jì)南汽車音響http://www.szanyuda.com/濾波器有電源濾波器、訊號(hào)濾波器、隔離網(wǎng)等。濾波器主要用途在消除噪聲，使聲音由喇叭出來(lái)時(shí)沒有其它雜音，但是電源或訊號(hào)濾波器，在非必要時(shí)能不用盡量不要用，因其在消除雜音時(shí)同時(shí)會(huì)產(chǎn)生壓降及降低音響本身訊號(hào)的dB值，可能會(huì)漏失掉少許該有的聲音，所以建議安裝者如果可以，先用其它方法處理，當(dāng)其它方法無(wú)法處理時(shí)才考慮使用電源或訊號(hào)濾波器。像隔離網(wǎng)為非導(dǎo)電PE材質(zhì)，包覆于線材上，不僅可保護(hù)線材，更可凈化線材內(nèi)部噪聲、避免外界噪聲干擾，雖然不用直接焊接于在線，但使用起來(lái)必有意想不到的效果。  

Jinan car audio filter has power filters, signal filters, isolation net. The main purpose of the filter to eliminate noise, the sound from the speaker when no other noise out, but the power or signal filters, when non-essential can not try not to use, because when you eliminate the noise generated at the same time reduce the pressure drop and the sound itself dB value of the signal, you may lose a little leak that some sound, it is recommended that the installer if you can, to use other means, and when other methods can not only consider the use of power or signal processing filter. Net non-conductive PE as isolation material, coated on the wire, the wire can not only protect, but also purify the wire internal noise, avoid external noise, though not directly welded to online, but must use an unexpected effect.
