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."
