- High Thermal Resistance Voice Coil: Equipped with a 35 mm 4 Ω voice coil, wound on six layers of pure copper on a high thermal resistance glass fiber support for durability and power handling.
- Optimized Magnetic Group: Magnetic group geometry optimized with proprietary software to achieve high undistorted Sound Pressure Level (SPL) even at high excursions.
2. Installation and Setup
Proper installation is crucial for optimal performance and longevity of your Hertz CS 200 S4 subwoofer. It is recommended that installation be performed by a qualified professional.
2.1 Enclosure Optimization
The CS 200 S4 is designed for optimal performance in sealed or ported enclosures with a minimum volume of 9.6 liters. Consult a car audio specialist or use a speaker box calculator to determine the ideal enclosure size and type for your specific vehicle and desired sound characteristics.
2.2 Wiring
The subwoofer features a 4Ω Single Voice Coil (SVC). Ensure your amplifier is stable at a 4Ω load. Connect the positive (+) terminal of the subwoofer to the positive (+) output of your amplifier and the negative (-) terminal of the subwoofer to the negative (-) output of your amplifier. Use appropriate gauge speaker wire for the power level of your amplifier.

3. Operation
Once installed, proper operation ensures the best audio experience and extends the life of your subwoofer.
3.1 Amplifier Matching
Ensure the amplifier used to power the CS 200 S4 is appropriately matched in terms of power output (RMS wattage) and impedance (4Ω). Overpowering or underpowering can lead to damage or poor performance. Consult the subwoofer's specifications for recommended power handling.
3.2 Break-in Period
Allow a break-in period of approximately 20-30 hours of normal listening before pushing the subwoofer to its maximum capabilities. This allows the suspension components (surround and spider) to loosen up and reach their optimal compliance, improving overall performance and longevity.
4. Care and Maintenance
Regular care will help maintain the performance and appearance of your subwoofer.
- Cleaning: Use a soft, dry cloth to gently wipe down the cone and surround. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Periodically inspect the speaker terminals and wiring connections to ensure they are secure and free from corrosion.
- Protection: If the subwoofer is installed in an exposed area, consider using a protective grille to prevent accidental damage to the cone.

5. Troubleshooting
If you experience issues with your subwoofer, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | Loose wiring connection; Amplifier off or in protect mode; Incorrect amplifier settings. | Check all wiring connections (power, ground, signal, speaker). Verify amplifier is powered on and not in protect mode. Adjust amplifier gain and crossover settings. |
| Distorted Sound | Amplifier gain too high; Clipping; Incorrect crossover settings; Damaged subwoofer. | Reduce amplifier gain. Check for proper crossover frequency settings. Ensure amplifier is not clipping. Inspect subwoofer cone and surround for physical damage. |
| Weak Bass | Incorrect enclosure size; Phase issue; Low amplifier power; Incorrect low-pass filter setting. | Verify enclosure volume meets specifications. Check phase setting on amplifier or head unit. Ensure amplifier provides sufficient RMS power. Adjust low-pass filter to appropriate frequency. |
If the problem persists after attempting these solutions, please contact Hertz customer support or a certified car audio technician.
