How to Connect Car Audio Wires?
2 Answers
Connect the two 6-inch speakers in parallel at the front doors, with the white wire connecting to the front right speaker. The gray wire connects to the front left speaker. Sony CD players cannot directly drive subwoofers; if the subwoofer has a built-in amplifier, you can add a low-frequency line to the RCA interface.
I usually enjoy modifying my car myself, and changing the audio system wiring is a basic task. First, you need to prepare the tools: a screwdriver to remove the panels, wire strippers to handle the cables, and a multimeter and insulating tape as backups. Before removing the old audio system, disconnect the negative terminal of the car battery to prevent short circuits or electric shocks—safety first. Then, follow the wiring diagram: the new audio system’s power wire is usually yellow (connected to constant power, i.e., the positive terminal of the battery), red (connected to the ACC power from the ignition switch), and the black wire must be securely grounded to a metal part of the car body. The speaker wires have four channels, with colors corresponding to front left, front right, rear left, and rear right—use cable connectors to secure them and avoid looseness. During testing, first connect only the power and ground wires, then turn on the audio to check for sound. Remember, don’t randomly cut the original car wiring harness; using compatible plugs is the easiest solution. If the wires are aged, replace the entire wiring harness directly to avoid overload and smoking. The whole process is simple but requires patience—it can be done in half an hour. After installation, don’t forget to lock the panels securely and test all functions before driving to ensure road safety without any hazards.
