Stock amplifier wire identification.

Can anyone help? Is there a pdf file or something to help?
Thanks,

I'm new to mercedes and dont wanna guess at which wires are which.
The manual does not have the wiring schema for the amplifier. Only trick you can do : use the back (back shelves) speakers as the trigger switch for you amp (I used that trick for my bass box amplifier). Leave the wiring intact, connect the power for the amp. from the battery (direct wired). Hope this will help.
