Hello, I’ve had a little bass ne toxic power amplifier and a Mac Audio Ice Cube subwoofer in my car. I think because of a little humidity, the stage has switched to protection often at first, but that’s what happened. The Woofer arteitete over a year great, but when much more often he went out and finally he didn’t go at all. I then took off the magnet and fixed that the wire which is wound up on the back plate, totally worn out r. To the transition I then put in a bass roll which lasted exactly one day until this problem occurred again. Does someone have an idea what that can be? Had the power stage moved to 4ohm 500watts, what they would have had to endure from where they also had 4ohm and 250watt rms. I hope someone can help me with this, already thank you in advance Mica
