Had a rattle on the Escape and low volume on one of the Focus speakers. Thought it was a simple wiring issue, I was a bit surprised on what I found after pulling door panels off. These dB speakers isn't even 10 years old, wonder why the degraded like they did? The back Pioneer 6x8's are almost 20 years old and still in good condition. On the Focus one of the Pioneer 6x9's tore the voice coil, the other side including the factory speakers are still in good shape. Ordering some Pioneer 6x8's to put back in.
