5.2. Adapter and Speaker Installation
- Mount Adapter: Position the Scosche SA68 speaker adapter into the factory speaker opening. The adapters are designed to use existing vehicle mounting points, so no cutting or drilling should be required for the adapter itself. Secure the adapter using appropriate screws.

- Wire New Speakers: Connect your new aftermarket speakers to the vehicle's wiring. If your aftermarket speakers do not directly plug into the factory harness, you may need to use splice connectors or a pre-wired speaker harness (sold separately) to make the connections. Match wire colors carefully (typically positive to positive, negative to negative).

- Test System: Turn on your vehicle's audio system and test all speakers to ensure they are functioning correctly and producing clear sound.
6. Operating and Maintenance
Once installed, the Scosche SA68 speaker adapters require no specific operation. They function passively to hold your speakers securely.
For maintenance, periodically check the speaker mounting screws for tightness to prevent vibrations. Keep the interior of your vehicle clean to avoid dust and debris accumulation around the speakers, which can affect sound quality over time.
7. Troubleshooting
- No Sound from New Speakers:
- Verify all wiring connections are secure and correctly matched (positive to positive, negative to negative).
- Ensure the vehicle's audio system is powered on and the volume is up.
- Check the vehicle's fuse box for any blown fuses related to the audio system.
- Poor Sound Quality or Vibrations:
- Ensure the new speakers are securely mounted to the adapters and the adapters are firmly attached to the vehicle's door frame.
- Check that the speaker wires are not pinched or shorting.
- Confirm that the speaker's maximum top mount diameter does not exceed 5 1/16" (129mm) to ensure proper fit within the adapter.
- Adapter Does Not Fit Vehicle Opening:
- Double-check the vehicle compatibility list in Section 4 to ensure the SA68 is the correct adapter for your specific vehicle make, model, and year.
