4. Setup and Installation
Proper installation is crucial for optimal performance. If you are unfamiliar with car audio installations, it is recommended to seek professional assistance. Always disconnect the vehicle's battery before beginning any electrical work.
4.1. Planning the Installation
- Location Selection: Identify suitable locations in your vehicle for the woofers and tweeters. Woofers are typically installed in door panels or kick panels, while tweeters can be mounted in A-pillars, dash, or door panels for optimal sound staging.
- Crossover Placement: Crossovers should be placed in a dry, accessible location, away from heat sources and moisture.
- Wiring: Plan your wiring paths to avoid interference with vehicle electronics and to ensure sufficient cable length. Use appropriate gauge wiring for power and speaker connections.
4.2. Woofer Installation (DV 165.3)
The DV 165.3 woofers are 6.5 inches (165mm) in diameter. Ensure adequate mounting depth and clearance. Refer to the dimensions diagram below.
- Carefully remove the existing speakers or prepare the mounting location.
- If necessary, use speaker adapters or mounting rings to secure the woofer.

5. Operating Instructions
Once installed, the Hertz DSK-1653 system operates as part of your car's audio system. Follow these guidelines for optimal performance:
- Initial Power-Up: After installation, reconnect the vehicle's battery. Turn on your head unit or amplifier at a low volume level to verify all connections are correct and sound is produced from all components.
- Break-in Period: Allow a break-in period of approximately 20-30 hours of normal listening. During this time, the speaker components will loosen up, leading to improved sound quality and bass response. Avoid playing music at excessively high volumes during this period.
- Volume Control: Adjust the volume to a comfortable listening level. Avoid prolonged listening at maximum volume, which can lead to distortion and potential damage to the speakers.
- Audio Settings: Use your head unit or amplifier's equalizer and sound settings to fine-tune the audio to your preference. Start with flat settings and make small adjustments.
6. Maintenance
The Hertz DSK-1653 speakers require minimal maintenance to ensure long-lasting performance.
- Cleaning: Periodically wipe the speaker grilles and surrounds with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
- Moisture: Protect the speakers from excessive moisture. While the woofer cone is water-repellent, direct exposure to water should be avoided.
- Inspection: Occasionally inspect the wiring connections to ensure they remain secure and free from corrosion.
7. Troubleshooting
If you encounter issues with your DSK-1653 speaker kit, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from speakers | Loose wiring connection Incorrect polarity Amplifier/head unit issue | Check all speaker and crossover connections. Verify correct positive (+) and negative (-) wiring. Test amplifier/head unit with another speaker. |
| Distorted or unclear sound | Over-driving speakers (volume too high) Incorrect gain settings on amplifier Loose speaker cone/surround | Reduce volume. Adjust amplifier gain settings according to manufacturer recommendations. Inspect speakers for physical damage. |
| One speaker not working | Faulty speaker wire Crossover issue Damaged speaker | Check wiring for continuity. Verify crossover connections for that specific speaker. Swap speakers to isolate the problem. |
If these steps do not resolve the issue, contact Hertz Audio customer support or a qualified car audio technician.
