車子是老車了,還在用老掉牙的原廠音響+換片箱,也沒有擴大機。
本來工作的好好的,有一咪咪的電流音也就當作沒聽到。
只是前陣子愈來愈大聲,就買了罐清潔劑對著換片箱噴,想看看會不會改善
很不幸換片箱被我噴死掉…Q_Q
後來殺了一組中古良品想頂著用,結果電流音更大了…= =a
目前是排除是換片箱的問題,因為開收音機也會有。(稍晚會拔掉換片箱再作測試。)
引擎關掉只開紅火就不會有聲音,發動後這個聲音會因為油門開度而變大,
所以初步判斷是電流的干擾。
而且電路系統也是原廠的,並無改裝高壓線圈或矽導線。
電流音產生的原因,會是因為喇叭破損或是搭鐵嗎?
如果是因為這樣,是不是換兩個喇叭就可以解決了?
(那我就要準備自己拆內裝,找店家幫我換喇叭,以免被拆壞。)
或是更簡單,弄個負極接地就可以解決了?
另外,可以推薦台北/新北市地區對老車比較有耐心的音響店,或是弄電機的店嗎?
