Hello,
So if you didn't order it with the Dynaudio sound system then I recommend fitting it with the VW original part Helix audio reciever and subwoofer, from the dealer. It fits into the spare wheel slot so you would have to live without a spare wheel ( you get the flat tire repair kit as standard).
I have this system and it really improves on the sound of the original audio system. More bass especially.
Have fun
