What cable does the Volkswagen car CD RR+ connect to?

RR+ is the rear right speaker, connect to the positive wire. Maintenance precautions for car CD players: Changing discs: When the vehicle is driving on bumpy roads or passing speed bumps, try not to change discs. Strong bumps can easily cause disc misalignment. It is advisable to change discs when the vehicle is driving relatively smoothly or when parked. Standard discs: Standard discs should be used. Deformed discs, irregularly shaped discs, discs that are too thin or too thick, cut discs, and discs with adhesive labels can all cause disc jamming. Repairing faults: The mechanism of multi-disc CD players is complex. If a fault occurs, it must be repaired at a service station. Do not disassemble it arbitrarily to avoid expanding the fault range due to human error. Function buttons: Avoid switching buttons too frequently. Switching from one function to another always requires a certain time interval. Pressing the buttons multiple times in succession will cause the mechanism to work too frequently, leading to CD jamming.
When it comes to wiring the CD audio system in Volkswagen cars, I often do the modifications myself. Generally, you can tell by the wire colors: the red wire is the positive power supply, connected to the 12V battery; the black wire is the negative ground connected to the car body; the speaker wires are divided into front left (white), front right (gray), rear left (green), and rear right (purple). Be careful not to reverse them, or the sound quality will suffer. Also, note that the yellow ACC wire connects to the ignition switch control, and the blue wire is sometimes for the antenna amplifier control. Before wiring, always disconnect the negative terminal of the car battery to avoid short-circuit risks. All you need are a screwdriver and small pliers. Most Volkswagen systems use ISO standard connectors for easy plug-and-play—avoid cutting wires and use adapter kits instead. After the modification, test all functions to ensure everything works properly.
Wiring safety in cars is crucial, and Volkswagen audio wires are clearly marked: the red and yellow power wires correspond to positive input, the black ground wire is fixed to the metal frame, and the speaker wires for each channel are color-coded—reversing positive and negative will cause sound inversion. The risk lies in reversed power connections, which can blow fuses or damage the CD player, or even cause short circuits leading to fires. Therefore, always disconnect the power before working to ensure personal safety. I always check that each wire is securely connected and free of corrosion. If in doubt, don’t force it—seek help from a professional shop. Choose compatible wiring harnesses that match the vehicle model to avoid incorrect connections.
