Bose amplifier by-pass

[Sparks88]

Bit of a long shot, but does anyone know anyone who knows how to bypass the Bose amplifier on an 06 Audi A3?
Got an aftermarket sound system (Sony WX-900BT), powers UP shows that it's working, connects to phone and FM radio, but there's no sound in the speakers!
Fitted the original stereo and speakers are still working fine!
HELP PLEASE!

You need an adapter , depending on what OEM head unit you have but will be similar to this
