I used a BOSS Frequency converter $15 on Amazon. It uses the rear speaker wire (input), and outputs RCA cables (internally converts from High Frequency to Low). You connect your amp to these RCA cables and done. I installed amp/sub in 2013 A5 this weekend. Here is thread.

Do you only connect to the stock subwoofer to connect the amp to the audio?

I installed my remote wire for my amp the same way you did and I'm not getting any power to my amp.

I plugged my remote wire into this fuse and I I get no power to my amp.
I went with the iSimple but I can't figure out where this last wire is supposed to be plugged into.
I'm not sure where to connect my RCA either. Please help

After 2 days of searching forums, YouTube, owners manuals and Google I found this and it was my Bible through the whole install. Thank you.

Been watching this unfold - has anyone been able to take a B&O system and repurpose it into an old classic car?

This is where its is from - 2010 Audi S5 Bang & Olufsen Sound System with the Lear Amp.

Its optical...how do you power it and get it to work outside of an Audi car?
