A3 2017 Stock Sound System
I had a 2016 2.0 and I just got a2017 a3 2.0 Ambition ( Brazilian version) with stock sound system. Its the same sound system but its a huge difference. Theres no subwoofer control, no loudness and no bass. Anyone knows if its possible to increase subwoofer or loudness directly on the amplifier or maybe a MMI upgrade?
Any help will be welcome!
Thanks a lot
