FW: [M3] stereo questions

["Smith, Christopher E" <christopher.e.smith@xxxxxxxx>]

> I have a few stereo questions and dont' have any documentation on the
> factory radio system so pardon my ignorance.
> 
> 1. On my 90 M3, there is an amplifier mounted in the trunk between the LR
> quarter panel and the trunk lid support.  I believe it is a factory unit.
> 
> 	Do you know if this is a factory unit? 
> 	What is the output power of the amp? 
> 	Does the amp drive all speakers or just the rears?
> 2. There is a multi-pin connector hanging from the trunk area and also
> connects to the stereo:
> 	Is this cable for a CD changer?  
> 	Are the pinouts for this cable industry standard or will it only
> work with BMW changers?
> 3.  The cassette tape player does not work.  The two belts which drive the
> tape head are slipping.  Where can I buy replacement belts?
> 4. Do you know if the outputs of the stock stereo head are pre-amps or
> powered?
