Unverified分贝越高越费电且体积越大，蜗牛喇叭工作电流可达4-6A，原车细线束和喇叭继电器可能无法承受，需加装继电器与加粗线束79% similar Unverified改装喇叭功率匹配原则：功放输出功率应为喇叭额定功率(RMS)的1.5倍左右，例如喇叭RMS 60W应配约90W输出的功放，功放功率过低会导致削波失真烧毁喇叭75% similar Unverified多口同时输出时总功率会被分摊，标榜65W的双口机型同时充两设备可能每口仅30W左右，需看'多口同时输出'规格而非单口峰值75% similar Unverified多口充电头看总功率会误导：标注65W三口的产品，单口满速65W但三口同时使用时会降至30W+18W+18W左右，多设备用户应看单口最高功率而非总功率72% similar Unverified多口同时充电时总功率会被分摊,标称65W双口同时充实际每口可能只有30W左右,追求单设备快充应选择单口输出峰值高的型号72% similar
