I will explore further. I do know that when I flip the switch up and down, I will hear a slight pop but it takes a few times to get the subwoofer to engage. If the switch is bad and is only 2 wires connected to the circuit board, I would definitely consider replacing. The sub still sounds fine and if I do get the LFM, there is no reason I still can't use both if I fix this one.

Thanks,

Dave
