I recently picked up a 2004 Jeep Liberty and its speakers have a nasty buzz in them with any level of bass. At first I thought with a car this old a speaker or two would be loose or blown. But what seems weird to me is that every speaker has the same buzz in it.
Is it normal that all speakers (at least six of them) would blow out and buzz like this, or could there be some problem in the electronics that could cause it?
Don't know if any one here has any experience with this type of thing, but I thought I would ask the experts.
Thanks for any insight into this.

Thanks for all the feedback. I've got to decide whether it's worth the investment to replace all the speakers.
Happy holidays!
If it was abused its quite possible.

You left too many things out to really suggest anything - is it mechanical or electrical, does just one amp drive all 6+ speakers, what are you or the stereo doing when it happens, does it get louder and if so when.
Right off the bat since it is coming from all the speakers I would suspect alternator whine from a component inside the alternator going bad, followed by a bad component in the amps power supply or both.
Thanks for the feedback and questions. The speakers buzz with any signal- engine on or off. It doesn't change with acceleration, so I'm not sure it's alternator related.
When I first heard this distortion, I thought it was a typical mechanical problem -- blown or worn speaker. It doesn't sound like a typical electrical buzz. But what made me curious was when I listened to each speaker and every one of them made the same distortion. That seemed odd to me -- that they would all be blown out the same way and their distortion sound identical. That's why I posed the question -- wondering if anyone else had run into a situation like this before.
If they buzz with the engine off it is not the alternator. You may have a grounding issue or the stereo's chassis may need to be grounded to the car if not already. Check all the connections at the stereo and at each speaker. With a multimeter check each wire from stereo to speaker to check for miswiring or without a MM try disconnecting one speaker at a time at the stereo then listening for any change.
It's not odd. After 8 years in car hi Fi including OEM repair I be seen it all. People are pretty stupid at times.
