5.1. Pre-Installation Checks

1. Compatibility: Ensure the 6x8-inch speaker size is compatible with your vehicle's speaker openings.

2. Remove Old Speakers: Carefully remove door panels or speaker grilles to access the existing speakers. Disconnect their wiring.
3. Mount New Speakers: Place the Blaupunkt GTX680 speakers into the openings. Use the provided mounting hardware to secure them firmly. Ensure a snug fit to prevent vibrations.
4. Wire Speakers: Connect the speaker wires from your head unit or amplifier to the terminals on the Blaupunkt speakers. Pay attention to polarity (+ to + and - to -) to ensure correct phase and sound quality.
5. Test Connection: Before reassembling, temporarily reconnect the battery and test the speakers with low volume to ensure they are working correctly.

6. Operating Instructions

Once installed, your Blaupunkt GTX680 speakers will operate in conjunction with your car's audio system (head unit/amplifier).

• Initial Playback: Start with a low volume setting on your head unit. Gradually increase the volume to ensure all speakers are functioning and sound is clear.
• Audio Settings: Adjust the bass, treble, balance, and fader settings on your head unit to achieve your preferred sound profile. Avoid excessive bass or treble boost that can lead to distortion.
• Volume Levels: While these speakers can handle up to 300W peak power, prolonged listening at extremely high volumes can cause hearing damage and speaker fatigue. Listen at comfortable levels.
