3. Detailed explanation of basic wiring steps
1.Power connection: It is recommended that the main power cord draw power directly from the positive terminal of the battery, and a fuse needs to be installed (40-60A is recommended). The grounding wire should be selected from the exposed metal part of the car body.
2.Signal line connection: Use a shielded audio cable to connect the host and power amplifier. Pay attention to distinguish the left and right channels (white - left, red - right) and avoid parallel wiring with the power cable.
3.Control line connection: Connect the REM line of the power amplifier to the host control line (usually blue) to achieve the synchronous power on and off function.
4.Speaker wiring: Pay attention to the matching of positive and negative poles (+/- marks), use 16-18AWG oxygen-free copper wire, and welding or special terminals are recommended for the connectors.
4. Solutions to common problems
| Problem phenomenon | Possible reasons | Solution |
|---|---|---|
| There is an impact sound during ignition | Delay circuit failure | Install delay module |
| Electric current sound while driving | Poor grounding | Re-select the grounding point |
| Uneven volume between left and right | Reverse phase connection | Check speaker polarity |
| Intermittent Bluetooth connection | signal interference | Install magnetic ring filter |
5. Recommendations for popular audio accessories in 2023
1.Wire type: Jialibao pure copper power cord (4GA), Monster gold-plated RCA cable
2.Processor class: Alpine X09 DSP, Helix DSP.2
3.Tools: Stanley wiring harness pliers, WAGO quick terminal blocks
Safety tips:Be sure to disconnect the negative terminal of the battery before modification, and all wires must be insulated. It is recommended to be operated by professional technicians. New energy vehicles need to pay special attention to high-voltage system protection to avoid modifications that may affect the warranty.
Through the above structured data and detailed instructions, I believe you have a systematic understanding of car audio connections. During the actual modification, it is recommended to plan the solution first and choose the appropriate configuration solution according to the budget to obtain the best sound quality experience.
