Well the noise filters were OK so I swapped out different speakers. The bad news is the speakers couldn't handle the dirty power it literally melted the area around the cones that glue to magnet sleeve, as soon as I remove the speaker you could smell the familar sulphur. At least the exspensive amps seemed to survive.
Usually I do take out my Empeg from the car but the parking lot I'm in is so hidden nobody knows where it is. Nothing has ever been stolen in this place ever, but now I have a reason.

Is there any way to make the Empeg shutdown completely in the car so this wouldn't happen again in case I do leave it in again? I never use the wake function because it would drag the battery down too fast (big amps).
