I've got a factory Delco-Bose in my '84 Trans-Am with the bi-amp option. Some time ago, my rear speakers developed a low frequency 'rattle' whenever the bi-amp was turned on. With it off, the rattling is non-existant. Has anyone experienced this before and found out what's causing it?

Thanks...

Sometime the little black vent in the door jab will vibrate, sounding like its coming from the rear speakers.

Justin -ah that might actually answer something else I've been noticing- I've heard a rattle whenever I hit a bump just 'right' that seemed to be back around the rear speakers or inside the door (at least from what I can hear on the driver's side), but I've never been able to find any loose parts. I'll take a look at that vent.

However I'm sure that the original 'rattle' I'm talking about is coming from the speakers as it 'keeps to the beat' of the music. That is, it's not random, nor just happens whenver I hit a bump....

Thanks!
