Speaker grounding issue
I have this Sony CD/stereo and a pair of Rockford Fosgate 6x9 speakes....one in each door (they are metal - it is a 1967) and it has been working fine for nearly a year....about a week ago, the stereo starts giving me an error message about a speaker being wired wrong and cuts the driver's side one off to save the amp.....I searched everywhere for loose connections and/or frayed insulation and found none.....If i remove the speaker from the door, It works fine.....but once the "casing" of the speaker makes contact with the door, I get a buzz and the amp cuts out again. (I have examined the speaker and I can see nowhere that the connectors make contact with the casing)
What the Hell is going on here????!?!?!?! There is nothing else electrical in the door and if something was grounding to the body it should effect BOTH speakers.....PLUS, it has worked perfectly fine for 11 months.
Any clues?

Checked everything....no frays or splits anywhere.....and it has begun to work again. We will see for how long, I guess. The guys at Best Buy (what do they know?) suggested it may be a bad voice coil in the speaker....apparently they have seen this with Rockford Fosgate speakers before.

Next time it happens, swap the speakers - see if the problem follows the speaker or stays in the same door. If it follows - bad speaker, if not, wiring problem

Maybe the wires are backwards so the grounding from the door is conflicting with the hot feed on the speaker.

Sounds like wires too me also, and while removing the speaker you just pinched the break together again. Just run a new wire as its a cheap and easy fix. Are you sure its not grounding out on the inside door panel. It might have been close and a door slam or nudge of a foot caused it to ground. You might also try some of the that backing stuff (can't think of the name) for your speakers.

You guys are obviously NOT reading the posts....I HAVE checked the wiring from the Stereo ALL THE WAY to the speaker....NO Breaks, Frays twists, etc...the wire is in nearly perfect condition......the speaker would perform fine, connected to the wires and removed from the door....the moment the metal "casing" of the speaker came in contact with the door the problem occured.....since the speaker is at shoe level, i have a feeling that the voice coils may have received a kick or something that broke something inside....but at the moment it is working fine.

I used to go through a set of speakers a year. Good ones, cheap ones, didnt matter. Between slamming the doors and water running inside the door, they just didnt last
last set I got was a pair of Sony marine. They sound good and have lasted five years so far.
