[BiturboS4] audio upgrades

Four blown so far.  Passenger rear three times drivers rear once.  So far
they have replaced under warranty but this is kind of ridiculous.  After
they replaced the second one I asked the service center about it but they
have no explanation.  AudiWorld has a tech note on adjusting the EQ settings
so I turned down the bass on the rear speakers thinking that might help and
still I blew both rears after that modification.  I too will claim that I
don't listen to the stereo at a level that should be capable of blowing a
speaker (why don't they have fuses anyway?)  I paid extra for the Bose
stereo for crying out loud.

I've had two or three replaced so far. And I don't listen to music that loud
(or maybe I'm deaf). I've heard a lot of people with speaker problems.

To add to Rob's input, there is a way to turn off the Bose acustic settings.
I'm not sure if that would make a difference, but I wouldn't replace just
speaker anyway (unless it were the exact same speaker).
