Hello everyone. I am new here and looking for some answers.

How can one upgrade their audio system in the A8 with external amps?

The goal is: MMI to digital audio processor via optical > Amp/s > Drivers

I'd like to remove all factory amps and speakers that came with the A8 and replace them with my own. Factory came with 8 speakers and a sub.

So the real question is, what component/s do i need to go from MMI to my processor?
