Unverified90% confidenceDecision RuleTime unknown
音箱/功放搭配时喇叭阻抗必须匹配：8Ω喇叭接标注8Ω的功放，若把4Ω喇叭接8Ω输出功放会导致功放过热甚至烧毁，多个喇叭并联会降低总阻抗，串联会升高，需重新计算总阻抗

Unverified音箱与功放的阻抗要匹配，多数家用音箱6-8欧姆，功放最低支持阻抗需≤音箱阻抗，用4欧姆音箱配仅支持6欧姆的功放会导致过热保护或损坏78% similarUnverified音箱阻抗与解码功放不匹配（如4欧音箱配仅标注8欧稳定的机型）会触发过热保护或音质劣化，选购前需确认功放对4欧负载的持续输出能力74% similarUnverified背景音乐主机功放的每路输出功率应≥所接喇叭总功率的1.2-1.5倍，避免长时间大音量导致过热保护或音质失真72% similarUnverified喇叭灵敏度(dB)高低影响功放需求：灵敏度≥90dB的高效率喇叭用原车功放即可推响，灵敏度＜88dB的喇叭必须加装独立功放，否则声音发闷无力72% similarUnverified多单元动铁耳机对输出阻抗敏感，放大器输出阻抗应＜1Ω（最好＜0.5Ω），否则会改变频响曲线导致声音失真，选购时查看Output Impedance参数72% similar
