This manual provides essential information for the proper installation, operation, and maintenance of your subwoofer, ensuring optimal performance and longevity.
The X-W12D4 features dual 4-ohm voice coils, a 24mm linear Xmax, and robust construction designed to move significant amounts of air with accuracy and control. It is an ideal match for high-power amplifiers, such as the Alpine X-A90M 900W mono ampaktar ħaj.
2. Informazzjoni dwar is-Sigurtà
Please read all safety instructions carefully before installing and operating the subwoofer. Failure to follow these guidelines may result in injury or damage to the product or vehicle.
- Installazzjoni Professjonali Rakkomandata: Due to the complexity of car audio systems and high power requirements, professional installation is highly recommended.
- Immaniġġjar tal-Enerġija: Tiżgura tiegħek amplifier's power output matches the subwoofer's RMS power handling (900W RMS). Overpowering or underpowering can lead to damage.
- Ventilazzjoni: Kun żgur li jkun hemm ventilazzjoni adegwata madwar is-subwoofer u amplifier biex jipprevjeni sħana żejda.
- Wiring: Use appropriate gauge wiring for power, ground, and speaker connections. Incorrect wiring can cause electrical shorts or fire hazards.
- Immuntar Sikur: Always mount the subwoofer securely within its enclosure and the enclosure securely within the vehicle to prevent movement during driving.

4. Setup u Installazzjoni
Proper setup is crucial for optimal performance and longevity of your subwoofer.
4.1. Għażla tal-Għeluq
The X-W12D4 is designed to perform well in various enclosures. For best results, consider a custom-built sealed or ported enclosure tuned to the subwoofer's specifications. A common recommendation for a sealed enclosure is approximately 0.75 cubic feet.
4.2. Immuntar
The subwoofer requires a mounting depth of 7-1/4 inches. Ensure sufficient clearance behind the subwoofer for proper air circulation and to prevent contact with any obstructions.

4.3. Wiring Dual Voice Coils
The X-W12D4 features dual 4-ohm voice coils, offering flexibility in wiring configurations to match your amplifier's impedance requirements. Common configurations include:
- Series Wiring (8 ohms): Connect the positive terminal of VC1 to the negative terminal of VC2. The amplifier connects to the negative terminal of VC1 and the positive terminal of VC2. This results in a total impedance of 8 ohms.
- Parallel Wiring (2 ohms): Connect the positive terminals of VC1 and VC2 together. Connect the negative terminals of VC1 and VC2 together. The amplifier connects to the combined positive and negative terminals. This results in a total impedance of 2 ohms.
Dejjem kun żgur li tiegħek amplifier is stable at the chosen impedance. Refer to your amplifier's manual for compatible load impedances.

5. It-Tħaddim tas-Subwoofer
The Alpine X-W12D4 is designed for high-performance bass reproduction. To achieve the best sound quality and prevent damage, consider the following:
- AmpTqabbil tal-Lifier: Uża an amplifier capable of delivering 900W RMS at the chosen impedance. An underpowered amplifier can lead to clipping and damage, while an overpowered amplifier can cause mechanical failure.
- L-issettjar tal-gwadann: Properly set the amplifier's gain to match the output voltage of your head unit. Do not use the gain control as a volume knob; it should be set to prevent distortion at maximum head unit volume.
- Settings tal-crossover: Uża tiegħek amplifier's or head unit's low-pass filter (LPF) to send only low frequencies to the subwoofer. A typical LPF setting for this subwoofer is between 60Hz and 80Hz.
- Filtru Subsoniku: Jekk tiegħek amplifier has a subsonic filter, enable it to protect the subwoofer from playing frequencies below its resonant frequency, which can cause excessive excursion and damage.
- Perjodu ta' Break-in: Allow a break-in period of approximately 20-30 hours of moderate listening before pushing the subwoofer to its limits. This allows the suspension components to loosen up and perform optimally.
6. Manutenzjoni
The Alpine X-W12D4 subwoofer requires minimal maintenance to ensure long-term performance.
- Tindif: Periodically wipe down the subwoofer and grill with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
- Spezzjoni: Regularly inspect the speaker cone, surround, and spider for any signs of damage, tears, or fatigue. Check all wiring connections for tightness and corrosion.
- Kundizzjonijiet Ambjentali: Evita li tesponi s-subwoofer għal temperaturi estremi, dawl tax-xemx dirett għal perjodi twal, jew umdità eċċessiva.
7 Issolvi l-problemi
If you experience issues with your Alpine X-W12D4 subwoofer, refer to the following common problems and solutions:
| Problema | Kawża Possibbli | Soluzzjoni |
|---|---|---|
| L-ebda ħoss mis-subwoofer | Ebda setgħa li ampwajers maħlula; amplifier in protect mode; incorrect gain setting; head unit not sending signal. | Iċċekkja amplifier power and ground connections. Verify remote turn-on wire. Inspect all speaker wires. Reset amplifier. Adjust gain. Ensure head unit is on and sending audio. |
| Bass distort jew mhux ċar | Amplifier gain set too high (clipping); incorrect crossover settings; damaged voice coil; poor enclosure. | Naqqas amplifier gain. Adjust LPF and subsonic filter settings. Inspect subwoofer cone and surround for damage. Ensure enclosure is sealed and properly sized. |
| Subwoofer smells burnt | Overpowering; prolonged clipping; voice coil overheating. | Immediately reduce volume. Check amplifier gain and ensure it's not clipping. Verify amplifier power matches subwoofer RMS. Allow subwoofer to cool. If smell persists or performance degrades, the voice coil may be damaged and require replacement. Note: A slight smell during initial break-in is normal, but strong, persistent burning indicates an issue. |
| Bass dgħajjef jew imdardar | Incorrect wiring (e.g., out of phase); insufficient power; improper enclosure tuning. | Ivverifika l-polarità korretta tal-wajers. Kun żgur amplifier is providing sufficient power. Consult with an audio professional for enclosure optimization. |
If troubleshooting steps do not resolve the issue, contact Alpine customer support or a qualified car audio technician.
