repeated alternator failures on 12v VR6, A3s?

I have a 98 Golf VR6 and am on my third alternator (the extended coverage turned out to be useful after all). The folks at the local dealership are perfectly good at fixing it, not so helpful on persistent causes.
Has anyone had any similar trouble with persistent fails? The car just gets basic daily use and the occasional long haul trip (plus necessary demonstrations to various yahoos that their reflexes are slow and so is their car). The only change to the car from stock is a Blaupunkt in-dash and changer, and the alternator probs started before that...
Any explanations, alternatives, suggestions of interest.

Take your alternator to an auto electrical specialty shop, or the next time it burns out have the dealer take it. Have them check all the diodes and triodes (smaller than diodes). Most likely you have a defective one. I had a 911 with a defective triode. It took three tries before the electrical specialist found it, but eventually we got it fixes and it worked perfectly. I am now an expert at removing and installing 911 alternators.
