Operating Instructions
Once properly installed, your Scosche HD4004A-WM1SD speakers will function as part of your vehicle's audio system. Ensure your car's head unit (stereo) is powered on and set to your desired audio source.
- Volume Control: Adjust the volume through your car's head unit. Avoid excessively high volumes for prolonged periods to prevent speaker damage.
- Audio Settings: Utilize your head unit's equalizer and audio settings (bass, treble, balance, fader) to fine-tune the sound to your personal 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 their optimal sound quality.
Maintenance
To ensure the longevity and performance of your speakers, follow these simple maintenance guidelines:
- Cleaning: Gently wipe the speaker grilles and surrounds with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Protection: Ensure the speaker grilles are always in place to protect the cones from physical damage.
- Environmental Factors: While designed for car environments, avoid exposing speakers to extreme moisture or direct sunlight for extended periods.
