    Speakers crackle when drivers side door is opened.

    Now this is a fucked up problem I got. Only and I mean ONLY when the drivers side door of my coupe is opened do I have loud crackly noises come from the cars speakers. Open passengers door and I have no problem. Turn on interior lights....again no problem. What the Heck?!

    I really do not know what it could be. My first thought was that it was the courtesy lights wire laying over a speaker wire or something and causing the commotion but this does not happen with the p.side door or when turning on the interior lights.


    Some background: feeding the speakers from an amp. Amp gets its inputs via rca's from the headunit preamp outputs.

    Don't remember when I first noticed the problem, though it has been around for many years now.

      yeah sounds like a wire is shorting where it passes from door to body. Probably if you pull the kick panel and the door panel you can wiggle stuff around and get the same effect.

        Yea, open the door and let the tunes play, then wiggle the harness between the door and A pillar. The crackle should change if there is a wire issue.

          Fuck....I guess I'll order up a new window channel molding (DON'T EVER BUY 30 year old NOS weatherstripping lol) and dick around with it then.

          While doing the proposed tests will/can damage be caused to the speakers? They ALL crackle when the drivers side door is open. I don't want to accidentally kill them all.

            Shouldn't cause any damage to the speakers - just wouldn't "overdrive" them with volume. If all the speakers crackle, perhaps it is a ground wire or if all the wiring goes through the drivers door the issues is there.

              likely to do more harm to the amp if something is grounding out that should not be.

              why do you need new weatherstripping? the window channel molding doesn't need to come out or be destroyed in order to check out the speaker wiring

                While the door panel is off I will just replace the waste of money NOS weatherstripping that is already showing signs of age.

                One more thing to add....I have drivers door open and I push the door plunger the crackles go away. Does that narrow it down some as to what I am looking for?

                  might be the door switch is the problem then. Try unplugging it and see if the problem continues.

                    I'll give it a shot one of these days and report back.

                    If the problem does go away what would that actually be telling me?

                      Door switch may be creating some sort of interference like a 60 Hz "hum". Worth a shot and then you can replace the switch later...

                        yeah, probably means the switch is arcing internally. If the lights flicker at all, that would also confirm that the switch is dinked.

                          Just plan on replacing head unit to new speaker and running new speaker wire to new speakers.

                            Removing the switch as opposed to just pushing the switch would do what?

                            Again door closed no problem, door open I have problems. Door open with plunger pushed closed no problem. Just trying to wrap my head around how the switch could be causing the problem when the switch activated the lights when the door is opened and turns off the lights when the door is closed.

                            In my mind there seems to be an issue somehow related to the courtesy lights ONLY within the drivers side door. Rotating the headlamp knob to turn on the interior lights does not recreate the problem when the door is closed.

                            Door open: problems, door closed no problem. Door open plunger closed, no problems.

                              The wires may be chafed in the conduit between the door and the body or in the kickpanel area. May just need some tape to seperate the wires.
