Informació de seguretat
- Desconnecteu sempre la bateria del vehicle abans de realitzar qualsevol treball elèctric.
- Ensure proper wiring and impedance matching to prevent damage to the subwoofer or amplifier. Refer to the "Wiring Configurations" section for details.
- Install the subwoofer securely to prevent movement during vehicle operation.
- Eviteu exposar el subwoofer a una humitat excessiva o a temperatures extremes.
- Es recomana una instal·lació professional per a un rendiment i una seguretat òptims.
Configuració i instal·lació
Requisits de tancament
The DD Audio 710d-D4 subwoofer is designed for optimal performance in properly constructed enclosures. For ported enclosures, a volume of 1.25 to 1.5 cubic feet is recommended. Ensure the enclosure is robust and sealed to prevent air leaks.
Muntatge
The subwoofer features a flush mount design. The mounting diameter required is 9 5/16 inches, and the mounting depth is 7 1/8 inches. Ensure sufficient clearance behind the mounting surface for the motor assembly.
- Carefully measure and cut the mounting hole in your enclosure according to the specified mounting diameter.
- Position the subwoofer into the mounting hole, aligning the screw holes.
- Secure the subwoofer using appropriate screws, ensuring even pressure around the mounting flange. Do not overtighten.
Configuracions de cablejat
The 710d-D4 is available in Dual 2-Ohm (D2) and Dual 4-Ohm (D4) voice coil configurations. Proper wiring is crucial for matching the subwoofer's impedance to your amplifier's stable operating range. Below are common wiring diagrams for dual voice coil subwoofers.
Nota: Always verify your specific subwoofer's impedance (D2 or D4) before wiring.
Dual Voice Coil (DVC) Wiring Examples:
- For a single DVC subwoofer:
- Cablejat de la sèrie: Connect the positive (+) of one voice coil to the negative (-) of the other voice coil. The remaining positive and negative terminals become the output. This doubles the impedance (e.g., two 4-ohm coils in series result in 8 ohms).
- Cablejat paral·lel: Connect both positive (+) terminals together and both negative (-) terminals together. The combined positive and negative terminals become the output. This halves the impedance (e.g., two 4-ohm coils in parallel result in 2 ohms).
- For multiple DVC subwoofers:
Combinations of series and parallel wiring can achieve desired final impedances. Consult your amplifier's specifications for stable impedance loads.
It is highly recommended to consult a professional car audio installer or refer to detailed wiring diagrams specific to your amplifier and subwoofer configuration to ensure correct impedance matching and prevent damage.
Pautes de funcionament
Període de rodament
Allow a break-in period of approximately 20-30 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 overall performance and longevity.
AmpCoincidència de lifier
The 710d-D4 has a recommended RMS power handling of 600 - 1200 Watts and a peak power handling of 3600 Watts. Select an amplifier that can provide sufficient clean power within this RMS range at the subwoofer's final impedance. Underpowering a subwoofer can be as damaging as overpowering it, as it can lead to amplifier clipping and distorted signals.
Configuració del guany
Ajusteu correctament el guany al vostre amplifier. The gain knob is not a volume control; it matches the ampsensibilitat d'entrada del lifter al volum de sortidatage of your head unit. Setting the gain too high can lead to clipping and damage to the subwoofer. Use a digital multimeter or an oscilloscope for accurate gain setting, or consult a professional.
Configuració de crossover
Utilize the low-pass filter (LPF) on your amplifier or head unit to send only low frequencies to the subwoofer. A typical starting point for the LPF is between 60Hz and 80Hz. Experiment with settings to achieve seamless integration with your main speakers.
Manteniment
- Neteja: Feu servir un drap suau i sec per netejar el con i l'entorn del subwoofer. Eviteu l'ús de productes químics agressius o humitat excessiva.
- Inspecció: Periodically inspect the subwoofer for any signs of damage, such as tears in the surround or cone, or loose connections.
- Factors ambientals: While designed for car audio, avoid prolonged exposure to extreme heat, cold, or direct sunlight, which can degrade materials over time.
