Audi a3 din 1 radio upgrade

[simasvai]

Hi everyone, I wanted to ask what kind of adapter I need for my Audi when changing from Audi consert din1 with an original subwoofer in rhe back when changing to an other radio

You need to get the non Bose loom, this will allow the head unit to activate the amp in the sub and you get rear speakers working too.
