正(zheng)確接線(xian)加裝(zhuang)功放，要(yao)做好準備(bei)、連接各線(xian)路并合理(li)布(bu)線(xian) 。

接(jie)(jie)線(xian)(xian)(xian)前，準備剝線(xian)(xian)(xian)鉗(qian)、螺絲(si)刀、電(dian)(dian)工(gong)膠帶等(deng)工(gong)具(ju)，選(xuan)好合適的(de)功(gong)放，了解設備接(jie)(jie)口(kou)，同時(shi)(shi)讓車(che)輛熄火并(bing)斷開電(dian)(dian)池(chi)負(fu)極(ji)(ji)。連(lian)(lian)(lian)接(jie)(jie)電(dian)(dian)源時(shi)(shi)，根據功(gong)放功(gong)率(lv)選(xuan)粗細合適的(de)電(dian)(dian)源線(xian)(xian)(xian)，將功(gong)放正極(ji)(ji)電(dian)(dian)源線(xian)(xian)(xian)連(lian)(lian)(lian)車(che)輛電(dian)(dian)池(chi)正極(ji)(ji)，且要通過合適的(de)保險絲(si)保護(hu)；負(fu)極(ji)(ji)電(dian)(dian)源線(xian)(xian)(xian)連(lian)(lian)(lian)接(jie)(jie)車(che)輛金屬(shu)車(che)身(shen)。連(lian)(lian)(lian)接(jie)(jie)音(yin)頻信號時(shi)(shi)，若車(che)輛音(yin)響(xiang)主機(ji)有(you)前置輸出接(jie)(jie)口(kou)，直(zhi)接(jie)(jie)用RCA線(xian)(xian)(xian)連(lian)(lian)(lian)接(jie)(jie)主機(ji)和功(gong)放音(yin)頻輸入(ru)端(duan)(duan)(duan)口(kou)；若沒(mei)有(you)，則使用高轉(zhuan)低轉(zhuan)換器轉(zhuan)換信號 。連(lian)(lian)(lian)接(jie)(jie)喇(la)(la)叭線(xian)(xian)(xian)要注意正負(fu)極(ji)(ji)對應，一般紅正黑負(fu)，連(lian)(lian)(lian)接(jie)(jie)功(gong)放喇(la)(la)叭輸出端(duan)(duan)(duan)與汽車(che)喇(la)(la)叭，并(bing)擰(ning)緊接(jie)(jie)線(xian)(xian)(xian)端(duan)(duan)(duan)子。

布線(xian)時要格外小心，避免(mian)線(xian)路與高溫或運動部件接觸，可(ke)使用(yong)線(xian)槽或束線(xian)帶(dai)整理固(gu)定。安裝后仔細檢查接線(xian)是否牢固(gu)，重新連接電(dian)池負極，啟動車輛測試音(yin)響(xiang)系統(tong)。做(zuo)好這些方面，就(jiu)能正確接線(xian)加(jia)裝功放，讓音(yin)質得到提(ti)升。
