Intermittent audio distortion (2004 VW Golf) -- SOLVED?
I *may* finally have managed to pinpoint the cause of the intermittent
static in the front left tweeter of my 2004 VW Golf (with aftermarket Kenwood receiver and stock Monsoon amplifier and speakers). Over the weekend, I put a few layers of electrical tape on either side of the big plug that (I believe) is what carries audio signals to and from the amplifier -- and then I pushed the plug in firmly, all the way, so it's held in place not only by the clips on the long sides (where I naturally didn't put electrical tape), but also by the extra bulk of the (slightly squishy) tape. The static problem appears to have basically disappeared. There may have been a couple spurts of brief static, which went away on their own, but for the most part, I'm hearing great sound now (including clean highs out of that tweeter). So it looks (or, shall I say, sounds?) like the main cause of the static problem was an intermittently bad contact in the connection to the amplifier. Presumably, the vibrations of driving would cause the plug to jiggle slightly, resulting in a bad connection (most likely in the wiring going to the front left tweeter, since no other speaker was ever affected). Sometimes, more vibration would make the connection become "good" again -- making the issue that much harder to track down. The plug was snapped "properly" into place, as far as I can tell, so the bad contact must presumably be something very subtle. Two questions. First, does this sound reasonable? Does this sort of thing happen in real life? :-} And second, is there a more "proper" way to fix a problem like this, or is padding the plug with electrical tape for a tight fit as good a solution as anything else?
