2. Informazioni sulla sicurezza

AVVERTIMENTO: La mancata osservanza di queste istruzioni di sicurezza può provocare incendi, scosse elettriche o altre lesioni o danni.

• Prima di iniziare qualsiasi installazione, scollegare sempre il terminale negativo della batteria del veicolo.
• Assicurarsi che tutti i cavi siano adeguatamente isolati e fissati per evitare cortocircuiti e danni.
• Non esporre il subwoofer a umidità o temperature estreme.
• Install the subwoofer in a secure location where it will not interfere with vehicle operation or passenger safety.
• Use appropriate gauge wiring for power and speaker connections as recommended by amplifier and subwoofer specifications.
• Excessive sound pressure levels can cause permanent hearing loss. Operate audio systems at moderate levels.

4. Configurazione e installazione

4.1 Considerazioni sul montaggio

The Alpine SWR-12D2 subwoofer requires a suitable enclosure for optimal performance. Ensure the enclosure dimensions accommodate the subwoofer's physical requirements.

• Profondità di montaggio: 6-3/8 pollici (16.2 cm)
• Diametro ritaglio: 10-7/8 pollici (27.6 cm)
• Dimensioni del prodotto: 8.7"D x 4"W x 7.1"H (approximate, refer to detailed specifications for exact measurements)

Secure the subwoofer firmly within the enclosure using appropriate fasteners. Ensure no air leaks around the mounting surface.

4.2 Cablaggio del subwoofer

The SWR-12D2 features dual 2-ohm voice coils, offering flexible wiring options to match your amprequisiti di impedenza del convertitore. Le configurazioni più comuni includono:

• 1-ohm Parallel Wiring: Collegare insieme i terminali positivi di entrambe le bobine mobili e i terminali negativi di entrambe le bobine mobili. Quindi collegare il positivo combinato al ampl'uscita positiva del lificatore e quella negativa combinata al amplifier's negative output. This results in a 1-ohm load.
• 4-ohm Series Wiring: Collegare il terminale positivo di una bobina mobile al terminale negativo dell'altra bobina mobile. Quindi collegare il terminale positivo rimanente alla ampl'uscita positiva del lifier e il terminale negativo rimanente al amplifier's negative output. This results in a 4-ohm load.

Always refer to your amplifier's manual for compatible impedance loads and wiring recommendations. Use high-quality speaker wire of adequate gauge for all connections.

4.3 Amplificatore Selezione

Seleziona un amplifier that can provide sufficient power within the subwoofer's RMS power handling range and match the impedance. The SWR-12D2 has a recommended RMS power handling of 300-1000 Watts.

• Gestione della potenza RMS: 300-1000 Watts
• Gestione della potenza di picco: 3000 Watt
• Impedenza nominale: Doppio 2 Ohm

An amplifier providing approximately 1000 Watts RMS at the chosen impedance (1-ohm or 4-ohm) is ideal for maximizing performance without risking damage.

5. Funzionamento

5.1 Initial Power-Up and Break-in

After installation, perform an initial power-up at low volume levels. Gradually increase the volume to ensure all connections are secure and the subwoofer is functioning correctly. A break-in period of several hours of moderate use is recommended to allow the subwoofer's suspension components to loosen and achieve optimal performance.

5.2 Tuning and Adjustment

Proper tuning of your amplifier and head unit settings is crucial for sound quality and subwoofer longevity.

• Impostazione del guadagno: Regolare il ampguadagno del lifier per abbinare il volume di uscitatage of your head unit. Avoid setting the gain too high, which can lead to clipping and damage.
• Filtro passa-basso (LPF): Imposta l'LPF sul tuo amplifier or head unit to filter out frequencies above the subwoofer's intended range, typically between 60 Hz and 100 Hz. The SWR-12D2 has a frequency response of 24 - 200 Hz.
• Filtro subsonico (HPF): If available, set a subsonic filter (high-pass filter for the subwoofer channel) to protect the subwoofer from playing extremely low frequencies below its resonant frequency, which can cause excessive excursion and damage. A setting around 25-30 Hz is often appropriate.
• Controllo di fase: Experiment with the phase setting (0° or 180°) on your amplifier or head unit to achieve the best blend with your front speakers.

6. Manutenzione

The Alpine SWR-12D2 subwoofer requires minimal maintenance to ensure long-term performance.

• Pulizia: Periodically wipe the subwoofer cone and surround with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or solvents.
• Protezione: Consider installing a protective grill (sold separately) to prevent accidental damage to the subwoofer cone and surround, especially in vehicle installations where objects might come into contact with the speaker.
• Ispezione: Regularly inspect wiring connections for tightness and signs of corrosion or wear.
