I know this must of been asked so much but I'm confused. I want to connect my Alpine Ida 311 head unit to Audi. It has a concert II installed at min so I know it not bose.
So what connectors do I need. I want all four speakers working. Head unit has all connectors for amps rcas and that. Don't mind finding a 12v for it because I had to do that on Alfa. Looked at autoload CT51-AU02 or pc9–
Thanks in advance
