I've got a Octavia 4, with the standard audio, Columbus HU. Trying to tame the centre speaker.

 

The speaker itself doesn't appear to be present on the speaker terminal block on the main quadlock connector of the headunit. Looking at the wiring diagrams on ERWIN, it only talks about a centre speaker being connected to a DSP amp, and no connector for one on the main head unit. I do however seem to have a working centre speaker (which I should like to reroute for my own DSP).

 

Does anyone know how this is connected? I feel I must be missing something obvious, as the diagrams don't refer to a centre speaker (not the Emergency call one - the audio one) for basic audio.

Hi,

 

I ran into the same problem.

Center speaker honks past the dsp, and ruins the whole system.

I've looked absolutely everywhere, every adaptation, every long coding (of which there aren't many at all for this car - it seems the VWs have a lot more for audio settings) - I was also hoping to be able to pull the sound dataset from the MIB3 to edit out the centre speaker, however it seems impossible with the MQB-EVO / MIB3 using anything off the shelf (or at least I'm not finding any sensible reports of doing so!) .

 

I'd love to get a flat EQ out which is possible by editing the sound datasets (I can flatten it in the DSP, however the EQ of the HU changes with volume, and I'd like to retain the factory volume controls).
