There is an audio sub board here

You need to identify the Year and Model number of your car.

If you have an 09 or older e9x and its a US model you will have
one of 2 systems.

If you have the HI FI system you can put an aftermarket amp in
fairly easily and it will sound better .

If you have a Logic 7 things will be much harder as there is a proprietary
fiberoptic connection between the Head Unit and Amp .

The head unit does not identify the model of the stereo .
A Logic 7 will have a dash center speaker and graphic equalizer control
in the radio display.

If you are near Fort Lauderdale the East Coast E9x stereo expert lives there his
handle is Technic he posts a lot on the board listed above . He can fix you up
no matter which system you have.
