Operating Instructions

The Alpine DM-65-G speakers operate as part of your vehicle's audio system. Once properly installed and connected to a compatible amplifier or head unit, they will reproduce audio signals.

• Volume Control: Adjust the volume through your head unit or amplifier. Avoid excessively high volumes that cause distortion, as this can damage the speakers.
• Audio Settings: Utilize your head unit's equalizer and sound processing features to fine-tune the audio output to your preference.
• Break-in Period: Allow a short break-in period (typically 10-20 hours of normal listening) for the speaker components to loosen up and achieve optimal sound quality.

Maintenance

Minimal maintenance is required for your Alpine DM-65-G speakers:

• Cleaning: Gently wipe the speaker grilles and surrounds with a soft, dry cloth to remove dust. Do not use harsh chemicals or abrasive cleaners.
• Inspection: Periodically check wiring connections for looseness or corrosion.
• Environmental Protection: Ensure speakers are protected from direct water exposure and extreme temperatures.
