正(zheng)(zheng)確(que)連(lian)接音響(xiang)和電(dian)瓶，要(yao)(yao)先確(que)定(ding)音響(xiang)電(dian)壓要(yao)(yao)求，選匹配電(dian)瓶，再(zai)用導線連(lian)正(zheng)(zheng)負極，并做好安(an)全措施。

確(que)定音響(xiang)(xiang)電(dian)(dian)壓(ya)(ya)要求是關(guan)鍵一步。通常音響(xiang)(xiang)使(shi)用12V直流(liu)電(dian)(dian)源，不過有(you)些雙電(dian)(dian)源供電(dian)(dian)的(de)音響(xiang)(xiang)需要特殊處理。只有(you)明確(que)這一點，后(hou)續才能順利進行。隨后(hou)，根(gen)據電(dian)(dian)壓(ya)(ya)要求挑選合適的(de)電(dian)(dian)瓶。確(que)保電(dian)(dian)瓶電(dian)(dian)壓(ya)(ya)與音響(xiang)(xiang)所需電(dian)(dian)壓(ya)(ya)精準匹配(pei)，如果(guo)電(dian)(dian)壓(ya)(ya)不符，就得借助降壓(ya)(ya)、升壓(ya)(ya)電(dian)(dian)路或逆變器來解(jie)決(jue)問題。

連(lian)(lian)接環節也(ye)(ye)不(bu)容(rong)忽視(shi)。用導線把電(dian)瓶正負極與音響電(dian)源(yuan)插(cha)孔相(xiang)連(lian)(lian)，若是延長電(dian)線，要(yao)留意(yi)顏色(se)對應，保證連(lian)(lian)接點牢固，并用絕緣材料包裹好，防止出現意(yi)外。要(yao)是音響系統(tong)還有其(qi)他設備，也(ye)(ye)要(yao)按照(zhao)各(ge)自要(yao)求連(lian)(lian)接，使(shi)用恰當(dang)的(de)電(dian)源(yuan)適配(pei)器或轉換器。

比(bi)如(ru)普通12V音響(xiang)(xiang)，直接(jie)把12V電(dian)瓶正負極連(lian)到12V電(dian)源插孔；雙電(dian)源音響(xiang)(xiang)需將兩塊12V電(dian)瓶串聯后(hou)連(lian)接(jie)；高電(dian)壓音響(xiang)(xiang)要借助(zhu)逆變器轉換(huan)后(hou)連(lian)接(jie)；低電(dian)壓音響(xiang)(xiang)則要用升壓電(dian)路提(ti)升電(dian)壓。操(cao)(cao)作時一定要關閉電(dian)源，若不確定如(ru)何操(cao)(cao)作，最(zui)好(hao)尋求專業幫助(zhu)，用絕緣材料保(bao)護好(hao)電(dian)線接(jie)頭，保(bao)障(zhang)連(lian)接(jie)過程(cheng)安全(quan)無誤 。
