Audi A4 B7 2008: Fun Improvements - Radio
One great thing about buying an older car is that you can still change the radio. In this case, I bought a Chinese Android car stereo that came with all of the necessary installation pieces in one package that is made to fit my car. It runs Android 7.1 and is basically a tablet that can also tune in radio stations. So far, I would say it is the coolest radio I have ever had and is the most cost-effective solution out there. Even the wiring harness and steering wheel controls are included with the package.
The one hurdle was fixing the level of the amplified rear speakers. In this version of Audi symphony, the rear speakers are amplified and require an odd voltage preamp for proper balance. A regular speaker line output (wires) is too much and the standard RCA pre-amp voltage leads to a nearly silent rear half of the car. The key is to use a line level converter to take the higher powered rear speaker wires and tone them down to and appropriate. The best part is that the converter will allow you to adjust the level conversion until it is just perfect.
Enfig.com makes a wiring harness fix for this line level problem, but don’t waste your money.
Awe, apps in the car with a touchscreen, life is good.
