師兄, 可能只係燒左 FUSE.
自檢,用萬用表在箱外檢查冇用架, bcoz it has a switching power supply.
有冇留意到>>"To power these innovative drivers, JL Audio engineered a new switching amplifier, featuring a regulated, switching power supply. This approach helps keep the amplifier section compact and efficient while delivering the necessary power to fully exercise the subwoofer driver's performance envelope." 回復ckman0302

可惜我冇JL.....{:6_204:}
師兄, 比$400 檢查, 送修喇. 若係 burnt 左 switching power supply 條fuse, even switcher , 都零件錢有限.
係燒個 class-D amp, 仲可以同番usa廠講數, 咬係 inherent manufacturing defect. 有消息!代理話要换底板$6000(連工包料+等貨返約2個時間!
好慘!不過代理話新底板設計會係個ICE側加個on/off.....唔通係舊設計有問題! 入面仲有一粒fuse 係PSU 入面仲有一粒fuse 係PSU
