How to Replace Broken Car Speakers by Easily Adapting Aftermarket Speakers
Here’s the procedure for replacing a car’s original speakers with aftermarket models (JVC CS-J620 300W 6.5" CS Series 2-Way Coaxial Car Speakers).
1. Removing the old speakers
First, remove the door panels or the area where the speakers are installed. Use screwdrivers or plastic tools to pry them off without scratching the surfaces. Once the panels are removed, disconnect the wires from the speakers. It’s important to take note of the wiring arrangement for later reference.
2. Checking the polarity
Properly connecting the wires is crucial to avoid poor sound quality. If the wires are already labeled with polarity signs (positive and negative), identifying them will be straightforward. If there are no visible labels, two methods can be used:
- Multimeter: Set the multimeter to voltmeter mode and connect the probes to the wires. If the reading is positive, the red probe is on the positive wire.
- Battery method: Briefly connect the speaker wires to a 1.5V battery. If the speaker cone moves outward, the positive terminal of the battery is connected to the positive wire.
3. Adapting the mounting
Aftermarket speakers may not perfectly match the original mounting holes. There are a few options:
- Adapters: If available, car-specific adapters allow easy mounting of the new speakers to the original supports.
- Modifying the supports: If adapters are not available, new holes might need to be drilled, or self-tapping screws can be used to secure the speakers. Care should be taken to avoid damaging any wires or components behind the support.
4. Connecting and testing
Once the new speakers are mounted, connect the wires, ensuring the polarity is correct as previously checked. Finally, reattach the panels and perform a sound test to verify the speakers are functioning correctly.
By following these steps, the replacement of the original speakers with aftermarket models can be successfully completed.
