Request a Audi Car Radio Stereo Wiring Diagram

Whether your an expert Audi mobile electronics installer, Audi fanatic, or a novice Audi enthusiast with an Audi, a Audi car stereo wiring diagram can save yourself a lot of time. Automotive wiring in Audi vehicles are becoming increasing more difficult to identify due to the installation of more advanced factory oem electronics.

One of the most time consuming tasks with installing an after market car stereo, car radio, satellite radio, xm radio, car speakers, tweeters, car subwoofer, crossovers, audio equalizer, car amplifier, mobile amp, car amplifier, mp3 player, ipod or any car audio electronics is identifying the correct color car audio wires for your Audi A3, Audi A4, Audi A4 Avant, Audi A5 Cabriolet, Audi A5, Audi A6, Audi A7, Audi A8, Audi Q7, Audi Q5, Audi Allroad, Audi S4, Audi S5, Audi S5 Cabriolet, Audi S6, Audi S8, Audi RS4, Audi RS6, Audi RS8, Audi R8, Audi R8 GT, Audi R8 Spyder, Audi TT-S Audi TT-RS or Audi TT.
