Hello!

Ever since I bought my A4, i've had an aftermarket stereo. I liked it, but because the car had been so well maintained by the previous owner, that the only thing it was spoiling was the radio.

Last week I finally bought an Audi Concert 2, with a Can Bus emulator, and keys.

After installing the radio, there are a couple important things that are not working.

The radio doesn't react to the ignition.

There is no connection to the back speakers.

It automatically cuts the sound for about one minute, if the volume is higher than 18.

One thing is clear, the cable that I bought, is not the correct one, and I don't know which one to buy.

http://m.ebay.de/itm/191076895566 <- this is the one I bought.

I've also heard I will need a plastic bit to put on the upper connection, I dont know how to explain it, but it helps to connect the cables to the back speakers. It'll probably already come with the new cable, if I buy the correct one.

Could you please help me? Can my problems be solved?

Because I really like the way my interior looks, there are just these small issues.

Thank you very much for your help!!
