4. Setup and Installation
4.1. Enclosure Requirements
The DS18 GEN-X104D subwoofer is designed to perform optimally in a properly constructed sealed or ported enclosure. Refer to the specifications section for recommended enclosure volumes and port dimensions. An appropriately sized and tuned enclosure is crucial for achieving the best sound quality and protecting the subwoofer.
4.2. Mounting the Subwoofer
Carefully place the subwoofer into the cutout of your enclosure. Ensure the mounting holes align. Use appropriate screws to secure the subwoofer to the enclosure, tightening them evenly to create a good seal. Avoid overtightening, which can strip screws or damage the subwoofer frame.

4.3. Wiring Configurations (Dual 4 Ohm Voice Coil)
The GEN-X104D features a Dual 4 Ohm Voice Coil (DVC) design, offering flexibility in wiring to achieve different impedance loads for your amplifier. Always ensure your amplifier is stable at the chosen impedance.
- Parallel Wiring (2 Ohms): Connect the positive terminal of Voice Coil 1 to the positive terminal of Voice Coil 2. Connect the negative terminal of Voice Coil 1 to the negative terminal of Voice Coil 2. Then, connect the combined positive to the amplifier's positive output and the combined negative to the amplifier's negative output. This configuration presents a 2 Ohm load.
- Series Wiring (8 Ohms): Connect the positive terminal of Voice Coil 1 to the amplifier's positive output. Connect the negative terminal of Voice Coil 1 to the positive terminal of Voice Coil 2. Connect the negative terminal of Voice Coil 2 to the amplifier's negative output. This configuration presents an 8 Ohm load.

It is crucial to verify the impedance with a multimeter after wiring to ensure it matches your amplifier's capabilities.
5. Operating Your Subwoofer
5.1. Break-in Period
Allow a break-in period of approximately 10-20 hours of normal listening before operating the subwoofer at high volumes. This allows the suspension components (surround and spider) to loosen up and reach their optimal compliance, improving performance and longevity.
5.2. Amplifier Settings
- Gain Setting: Set the amplifier's gain control carefully. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly. The gain control is not a volume knob; it matches the amplifier's input sensitivity to the head unit's output voltage.
- Low-Pass Filter (LPF): Set the LPF on your amplifier or head unit to filter out high frequencies from the subwoofer. A common starting point is between 80Hz and 120Hz, but this can be adjusted based on your system's overall sound.
- Subsonic Filter: If your amplifier has a subsonic filter, set it slightly below your enclosure's tuning frequency (for ported enclosures) to protect the subwoofer from over-excursion at very low frequencies.
6. Maintenance
The DS18 GEN-X104D subwoofer requires minimal maintenance to ensure long-lasting performance.
- Cleaning: Use a soft, dry cloth to wipe down the cone and surround. Avoid using harsh chemicals or excessive moisture, which can damage the materials.
- Connection Check: Periodically inspect all wiring connections to ensure they remain tight and free from corrosion. Loose connections can lead to power loss or damage.
- Enclosure Integrity: Check the subwoofer enclosure for any signs of damage, cracks, or air leaks, which can negatively impact sound quality.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound from Subwoofer | No power to amplifier, loose wiring, amplifier in protect mode, incorrect input signal. | Check amplifier power, ground, and remote turn-on connections. Verify all speaker wires are secure. Check amplifier's protection indicator. Ensure head unit is sending an audio signal. |
| Distorted Sound | Gain set too high, incorrect crossover settings, damaged voice coil, insufficient power. | Reduce amplifier gain. Adjust LPF settings. Inspect subwoofer for physical damage. Ensure amplifier provides sufficient RMS power. |
| Weak Bass Output | Incorrect wiring impedance, phase issue, improper enclosure, low gain setting. | Verify wiring matches desired impedance. Check phase setting on amplifier/head unit. Ensure enclosure is correctly sized and tuned. Increase amplifier gain gradually. |
| Subwoofer Overheating | Overpowering, improper impedance match, poor ventilation. | Reduce power to the subwoofer. Re-check wiring impedance. Ensure adequate airflow around the subwoofer and amplifier. |
