Hi every one. I'm new on here and new to audi. I have an a4 avant sline with no sub on the stereo, so my question is, can I just buy a sub and fit it and the sub controls will appear on the stereo or is that just wishful thinking 🤔. All advise welcome lol , cheers guys.

 

It is possible to add a sub, but it is better to hire a car electrician to do it.

 

Thanks for the reply. Not much info but atleast I know it will go in so thank you 👍.O I am an electrician but nice to know things 1st as I've not even dropped the side panel yet lol.
Thanks again 🙏
