w204 Harman/Kardon wiring to door speakers

[alexpez]

Hi, looking for some help with the wiring from the Harman/Kardon amp in the boot of my w204 to the two door speakers (tweeter and woofer/bass) on the drivers side.

I've had a look at the amp in the boot and it looks like there is single orange, brown/orange coming out of there, and I've had a look at the drivers door wiring, which looks like there are two sets of orange, brown/orange coming in (are the speaker wires held in big yellow connector block under the door control unit?). Can anyone confirm where the speaker wire that comes from the amp gets split in two to go to both the tweeter and the bass/woofer in the drivers door please?

I think it's fiber optic not traditional speaker wires?

There's a wiring diagram on HK audio location and wiring? that appears to show orange, brown/orange coming out of the amp, and getting split into green, brown/green for tweeter, and green, brown/green for bass. Just wondering if anyone knew where exactly that split is?

The electronics communicate via optical, speakers are still driven by electrickery over wires.

When I changed my CLS speakers there was a plug in the door that split out the speaker feeds for tweeter and woofer
