Aftermarket player fitting question

[Kido Skillz]

Hello guys,

As the volume it's not working anymore on my Concert radio (common problem on S3 8L), I want to fit a aftermarket player, but also I want it to work properly with my Bose system.

What parts should I get and how difficult is to do?

Cheers.
