由于汽車在行駛過程中會產生各種頻率的干擾，對汽車音響系統的聽音環境產生了不利的影響，因此對汽車音響系統的安裝布線提出了更高的要求。

1.-汽車音響配線的選擇

汽車音響線(xian)材(cai)的(de)電(dian)(dian)(dian)阻(zu)越(yue)(yue)小(xiao)，在線(xian)材(cai)上(shang)鎖小(xiao)號(hao)的(de)功(gong)(gong)率(lv)(lv)就越(yue)(yue)少，則系(xi)(xi)(xi)統(tong)(tong)的(de)效(xiao)(xiao)率(lv)(lv)越(yue)(yue)高。即使(shi)線(xian)材(cai)很粗，由于喇叭本身(shen)的(de)原因也會(hui)損失一定(ding)的(de)功(gong)(gong)率(lv)(lv)，而不會(hui)使(shi)整個(ge)系(xi)(xi)(xi)統(tong)(tong)的(de)效(xiao)(xiao)率(lv)(lv)達到100%。線(xian)材(cai)的(de)電(dian)(dian)(dian)阻(zu)越(yue)(yue)小(xiao)，阻(zu)尼系(xi)(xi)(xi)數(shu)越(yue)(yue)大；阻(zu)尼系(xi)(xi)(xi)數(shu)越(yue)(yue)大，則容(rong)許輸出的(de)功(gong)(gong)率(lv)(lv)越(yue)(yue)大。電(dian)(dian)(dian)源保(bao)險的(de)選擇主電(dian)(dian)(dian)源線(xian)的(de)保(bao)險盒月(yue)靠近車蓄電(dian)(dian)(dian)池街頭越(yue)(yue)好(hao)，保(bao)險值(zhi)(zhi)大小(xiao)可按(an)以下公式加以確定(ding)：保(bao)險值(zhi)(zhi)=（系(xi)(xi)(xi)統(tong)(tong)各功(gong)(gong)放的(de)總(zong)額定(ding)功(gong)(gong)率(lv)(lv)之和(he)×2）/汽車電(dian)(dian)(dian)源電(dian)(dian)(dian)源平(ping)均值(zhi)(zhi)。

2.專業汽車音響改裝-音頻信號線的布線

用絕緣膠帶或熱縮管將音(yin)(yin)頻(pin)信(xin)(xin)(xin)(xin)(xin)(xin)號線(xian)(xian)(xian)(xian)(xian)(xian)街(jie)頭處纏緊以保證絕緣，當(dang)接頭處和(he)(he)車體相接觸是(shi)，可(ke)產生噪(zao)聲。保持(chi)音(yin)(yin)頻(pin)信(xin)(xin)(xin)(xin)(xin)(xin)號線(xian)(xian)(xian)(xian)(xian)(xian)盡可(ke)能(neng)短。音(yin)(yin)頻(pin)信(xin)(xin)(xin)(xin)(xin)(xin)號線(xian)(xian)(xian)(xian)(xian)(xian)越長，越容易受到車內各種不同頻(pin)率(lv)信(xin)(xin)(xin)(xin)(xin)(xin)號的干擾，。注(zhu)意：如(ru)果不能(neng)縮短音(yin)(yin)頻(pin)信(xin)(xin)(xin)(xin)(xin)(xin)號線(xian)(xian)(xian)(xian)(xian)(xian)的長度，超(chao)長的部分要(yao)(yao)折疊起來，而不是(shi)卷起。音(yin)(yin)頻(pin)信(xin)(xin)(xin)(xin)(xin)(xin)號線(xian)(xian)(xian)(xian)(xian)(xian)的布(bu)(bu)線(xian)(xian)(xian)(xian)(xian)(xian)要(yao)(yao)離開行車電(dian)(dian)(dian)腦模(mo)塊電(dian)(dian)(dian)路(lu)和(he)(he)功放的電(dian)(dian)(dian)源線(xian)(xian)(xian)(xian)(xian)(xian)至(zhi)少20cm.。如(ru)果布(bu)(bu)線(xian)(xian)(xian)(xian)(xian)(xian)太近，音(yin)(yin)頻(pin)信(xin)(xin)(xin)(xin)(xin)(xin)號線(xian)(xian)(xian)(xian)(xian)(xian)會拾取到頻(pin)率(lv)干擾的噪(zao)聲。最好將音(yin)(yin)頻(pin)信(xin)(xin)(xin)(xin)(xin)(xin)號線(xian)(xian)(xian)(xian)(xian)(xian)和(he)(he)電(dian)(dian)(dian)源線(xian)(xian)(xian)(xian)(xian)(xian)分開不在駕(jia)駛座和(he)(he)副駕(jia)駛座兩(liang)側。注(zhu)意，當(dang)靠近電(dian)(dian)(dian)源線(xian)(xian)(xian)(xian)(xian)(xian)、微型計算機電(dian)(dian)(dian)路(lu)布(bu)(bu)線(xian)(xian)(xian)(xian)(xian)(xian)是(shi)，音(yin)(yin)頻(pin)信(xin)(xin)(xin)(xin)(xin)(xin)號線(xian)(xian)(xian)(xian)(xian)(xian)必須離開它們(men)20cm以上(shang)，如(ru)果音(yin)(yin)頻(pin)信(xin)(xin)(xin)(xin)(xin)(xin)號線(xian)(xian)(xian)(xian)(xian)(xian)和(he)(he)電(dian)(dian)(dian)源線(xian)(xian)(xian)(xian)(xian)(xian)需(xu)要(yao)(yao)互相交叉式，我們(men)建議最好以90°相交。

3.-電源的布線

所選用的電源線電流容量值應等于或大于和功放相接的保險管的值。如果采用低于標準的線材作電源線，會產生交流噪聲并且嚴重破壞音質。電源線可能會發熱而燃燒。當用一根電源線分開給多個功放供電時，從分開點到各個功放布線的長度應該盡量相同。
當電(dian)(dian)(dian)源(yuan)線(xian)(xian)(xian)橋接是，各(ge)個(ge)功(gong)放(fang)之間將(jiang)(jiang)出(chu)現電(dian)(dian)(dian)位差，這個(ge)電(dian)(dian)(dian)位差將(jiang)(jiang)導致交流噪聲(sheng)，從(cong)(cong)而嚴重破(po)(po)壞(huai)音(yin)質(zhi)。當主機直接從(cong)(cong)電(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)時(shi)(shi)，會(hui)減少(shao)噪聲(sheng)，提高音(yin)質(zhi)。把蓄電(dian)(dian)(dian)池接頭(tou)(tou)的骯臟(zang)物徹底清除，并將(jiang)(jiang)接頭(tou)(tou)擰緊。如果(guo)電(dian)(dian)(dian)源(yuan)接頭(tou)(tou)很臟(zang)或沒(mei)有(you)擰緊，接頭(tou)(tou)處(chu)就會(hui)接觸不良。而產(chan)(chan)生(sheng)阻流電(dian)(dian)(dian)阻的存(cun)在，會(hui)導致交流噪聲(sheng)，從(cong)(cong)而嚴重破(po)(po)壞(huai)音(yin)質(zhi)。用砂紙和(he)細挫(cuo)清除接頭(tou)(tou)處(chu)的污物，同時(shi)(shi)擦上黃油。當在汽車(che)動力系統內布線(xian)(xian)(xian)時(shi)(shi)，應避免在發(fa)電(dian)(dian)(dian)機和(he)點(dian)(dian)(dian)火裝置附(fu)近(jin)走線(xian)(xian)(xian)，發(fa)電(dian)(dian)(dian)機噪聲(sheng)和(he)點(dian)(dian)(dian)火器噪聲(sheng)能(neng)夠(gou)輻射入電(dian)(dian)(dian)源(yuan)線(xian)(xian)(xian)。當將(jiang)(jiang)原(yuan)廠安裝的火花塞(sai)和(he)火花塞(sai)線(xian)(xian)(xian)纜更換(huan)成高性能(neng)的類(lei)型(xing)是，點(dian)(dian)(dian)火火花更強，這時(shi)(shi)將(jiang)(jiang)更易(yi)產(chan)(chan)生(sheng)點(dian)(dian)(dian)火噪聲(sheng)。在車(che)體內布電(dian)(dian)(dian)源(yuan)線(xian)(xian)(xian)和(he)布音(yin)頻(pin)線(xian)(xian)(xian)鎖遵(zun)循的原(yuan)則(ze)一致。

4.專業汽車音響改裝-接地的方法

用細砂將車體(ti)接地(di)(di)點(dian)處的油漆(qi)去除干凈，將接地(di)(di)線(xian)固定緊。如(ru)果車體(ti)和(he)接地(di)(di)端之間(jian)殘(can)留車漆(qi)就會是接地(di)(di)點(dian)產(chan)生(sheng)接觸電(dian)阻。和(he)前文所述臟(zang)污蓄電(dian)池接頭類似，接觸電(dian)阻會導(dao)(dao)致交流噪聲的產(chan)生(sheng)，從而嚴重(zhong)破壞音質。將音響系統中各(ge)項(xiang)音響器材的接地(di)(di)集中于一點(dian)。如(ru)果不(bu)將它們集中一點(dian)接地(di)(di)，音響個組建之間(jian)存在的點(dian)位差會導(dao)(dao)致噪聲的產(chan)生(sheng)。

特別注意：

主機(ji)和(he)功放應(ying)該分別(bie)接(jie)(jie)地(di)。當系統消(xiao)耗(hao)電(dian)流很大(da)時(shi)，蓄電(dian)池接(jie)(jie)地(di)端一(yi)定要牢固。提(ti)高(gao)電(dian)源(yuan)接(jie)(jie)地(di)性能的(de)方(fang)法是，在電(dian)源(yuan)盒接(jie)(jie)地(di)間用粗直(zhi)徑的(de)線材布線，如絞(jiao)股(gu)線。這(zhe)樣(yang)做能夠加強連接(jie)(jie)，有效地(di)抑制噪聲并提(ti)高(gao)聲音質量。不要靠近行車(che)(che)(che)電(dian)腦(nao)布線。請記住，主機(ji)接(jie)(jie)地(di)點(dian)靠近行車(che)(che)(che)電(dian)腦(nao)的(de)接(jie)(jie)地(di)點(dian)或固定點(dian)是，會產生(sheng)行車(che)(che)(che)電(dian)腦(nao)噪聲。在汽(qi)車(che)(che)(che)內所布的(de)線材和(he)音頻線都要加上汽(qi)車(che)(che)(che)和(he)音頻線都要加上汽(qi)車(che)(che)(che)專用護套(tao)套(tao)管。
