Hi, I tried searching but have not been able to find information on how to identify which wires go to which speakers from the DSP amp to the speakers. Does anyone have a wiring diagram that identify these wires?

Found the wiring diagram at the bottom of the page up here; however, it seems to be for the non-DSP amp. Does anyone know if it's the same for the DSP amp's output to the speakers?

If it helps, I have 2003 X5 E53 with 16:9 nav and DSP audio

Thanks in advance.
