3. Informazioni sulla sicurezza
Osservare sempre le seguenti precauzioni di sicurezza:
- Installazione professionale consigliata: Installation of car audio components can be complex. If you are unsure about any step, seek assistance from a qualified professional installer.
- Scollegare la batteria: Prima di iniziare qualsiasi installazione, scollegare il terminale negativo della batteria del veicolo per evitare cortocircuiti e danni.
- Cablaggio corretto: Ensure all wiring is correctly connected according to the amplifier and subwoofer specifications. Incorrect wiring can lead to damage or fire.
- Ventilazione: Assicurare una ventilazione adeguata attorno al subwoofer e amplifier per evitare il surriscaldamento.
- Livelli del volume: Prolonged exposure to high volume levels can cause hearing damage. Use caution when adjusting volume.
- Montaggio sicuro: Montare saldamente il subwoofer per evitare che si trasformi in un proiettile in caso di arresto improvviso o incidente.
4. Configurazione e installazione
Proper installation is crucial for optimal performance and longevity of your subwoofer. This section provides general guidelines. Refer to your ampmanuale dell'installatore per schemi elettrici specifici e requisiti di alimentazione.
4.1. Choosing an Enclosure
The DB DRIVE K5 12D4V2 subwoofer requires a suitable enclosure for proper operation. Common enclosure types include sealed, ported (vented), or bandpass. The choice depends on desired sound characteristics and available space. Consult a car audio specialist or online resources for recommended enclosure volumes and tuning frequencies for this specific model.
4.2. Wiring the Subwoofer
The K5 12D4V2 features a 4-layer 4-ohm DVC (Dual Voice Coil) configuration. This allows for various wiring options to achieve different impedance loads at the amplifier. Common configurations include:
- Cablaggio parallelo (2 ohm): Connect the positive terminals of both voice coils together and the negative terminals of both voice coils together. This results in a 2-ohm load, suitable for amplifiers stable at 2 ohms.
- Cablaggio in serie (8 ohm): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. The remaining positive and negative terminals are then connected to the amplifier. This results in an 8-ohm load.
Always match the subwoofer's impedance load to the amplifier's stable impedance rating. Refer to the wiring diagram provided with your amppiù vivace.
4.3. Collegamento al Amppiù vivace
Connect the wired subwoofer to the appropriate speaker output terminals on your amplifier. Ensure polarity is correct (+ to + and - to -). Use high-quality speaker wire of adequate gauge to minimize power loss.

5. Istruzioni per l'uso
Once installed, follow these general guidelines for operating your subwoofer:
- Accensione iniziale: After installation, turn on your car's audio system at a low volume. Gradually increase the volume and check for proper operation.
- AmpImpostazioni lificatore: Regola il guadagno, la frequenza di crossover e le impostazioni di fase sul tuo amplifier to blend the subwoofer's output seamlessly with your main speakers.
- Guadagno: Set the gain to match the output voltage dell'unità principale. Evitare di impostarla troppo in alto, poiché ciò potrebbe causare distorsioni.
- Filtro passa-basso (LPF): Set the LPF to filter out frequencies above the subwoofer's intended range (typically 60Hz-100Hz).
- Fase: Adjust the phase (0° or 180°) to ensure the subwoofer's output is in sync with your main speakers, preventing cancellation or weak bass.
- Periodo di rodaggio: Allow a break-in period of approximately 20-30 hours of normal listening before pushing the subwoofer to its limits. This allows the suspension components to loosen up and perform optimally.
- Evitare il sovraccarico: Do not continuously play the subwoofer at distorted levels. This can cause permanent damage to the voice coil and other components.
6. Manutenzione
The DB DRIVE K5 12D4V2 subwoofer requires minimal maintenance:
- Pulizia: Utilizzare un panno morbido e asciutto per pulire il cono e la cornice. Evitare l'uso di prodotti chimici aggressivi o detergenti abrasivi.
- Ispezione: Periodically inspect the wiring connections to ensure they are secure and free from corrosion. Check the subwoofer's surround for any signs of cracking or damage.
- Fattori ambientali: Protect the subwoofer from extreme temperatures, direct sunlight, and moisture, which can degrade its performance and lifespan.
