Porsche 440

I have the CD/AM/FM unit without NAV and today the stereo will not put out any sound from the speakers , It seems the stereo is functioning properly, but absolutely no sound is coming out from the speakers. There was no noise or static when it happened, the sound just quuit while I was driving to work. Any ideas ??? Im thinking the amplifier ?? IT has the BOSE system

Just read through another post about this problem..... I went out and drove my car , and the stereo worked perfectly ..... There has to be a cure for this problem ??? It hasn't happened in the 6 months I have owned it, but it really pisses me off that it even happens as I commute 120kms every day and a stereo is a must !

Unfortunately happens periodically. I've found that if you turn it off and lock the car for about 5-10 minutes, it will reset and work fine again.

The sound is now totally gone and does not come back on .... I have it booked with the Dealer to diagnose the problem. The person I purchased the car from told me they changed out 3 Amplifiers on the car ??? IM thinking if they changed 3 amps out , there must be another problem ??

Intermittent head unit fiber optic transceiver
Cracked/Bent plastic optical fiber from head unit to amplifier

Is there a CDChanger or any other infotainment options in the car?
Any aftermarket equipment (mObridge/NAV-TV, etc) now or in the past?

I doubt you would have 3 bad amplifiers ...

nothing aftermarket all original OEM and has never had anyting else hooked up.

Where is the Amplifier located on my car? The operators manual does not show.

its above the cdc location rear passenger side behind the pull off door

if they tried 3 different amps i would go with ltc comments above he should know better than most (sic)

now what would make you think that?
It seems like so long ago...
