Re: the Bose Towering Inferno--still simmering?
Mr Harrison you make a good point, and I certainly hope that no one is so
cavalier as to take the path of "hounding Audi" until (a) they get free
speaker replacements or (b) their car is destroyed, whichever comes first.
The sad fact is that probably no one is yet really "hounding Audi". The
exception might be the lister who earlier this year reported losing his car
to a speaker fire. A concerted effort directed at Audi has yet to develop
because awareness of a possibly significant significant fire hazard is
just developing (during the past 6 to 12 months) within our small segment
of '91 200 owners. Naturally, the vast majority of owners are completely
unaware of even the suspicions of a hazard.
There's a psychological hurdle to taking the preemptive action you advise
(unless one already hates the Bose sound) when there is only limited (yet
provocative) information. Thus it's understandable that many owners--who've
only heard some rumors--are not rushing to perform a Bosectomy. Of course,
any who do reach the conclusion that a significant level of fire hazard
exists in their '91 Audi's rear speaker amps should certainly take
immediate steps to mitigate the situation. As I have become more and more
concerned over the past months, my reactions were to (1) carry fire
extinguisher and (2) become more vigilant about shutting the radio off
whenever the car was unattended (I don't have heavy-metal-crazed teenagers
roaming my garage). But DeWitt's "different take" prompts me to conclude
that I really should go at least one step further. I'll just disconnect
the damn things!
The "disconnect" approach is an easy short-term alternative to the process
of _replacing_ the rear Bose speakers with "new improved units" (such
things actually exist?). Pulling the plugs is a 2 minute task for even the
most maintenance-aversive owner, who needs to keep in mind that the world
got along quite well for decades without the availability of automobile
rear speakers. My advice: disconnect right now! Then give some thought to
speaker replacement and/or efforts to get information from Bose and Audi.
On the 200q20V maillist, it's now the practice to advise disconnection of
any rear speaker if there's _audible_ evidence of a malfunction. However
we must keep in mind that it's not established if speaker amps will
necessarily give an audible alert of their intention to combust.
