4. Konfigurazioa eta instalazioa
Proper installation is crucial for the performance and longevity of your subwoofer. It is highly recommended that installation be performed by a qualified professional.
4.1 Itxituraren Baldintzak
The G7 8.4 is designed for custom box mounting. Ensure the enclosure is properly sealed and braced to prevent air leaks and vibrations. Consult with an audio professional or use a reputable enclosure design software to determine the optimal volume and port tuning (if applicable) for your specific application.
4.2 Kableatutako konexioak
This subwoofer features a 4 Ω Dual Voice Coil (DVC) design. Proper wiring is essential to match the impedance requirements of your ampbizigarria. Kontsultatu zure amplifier's manual for compatible impedance loads. Common wiring configurations for DVC subwoofers include:
- Serieko kableatzea: Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. The remaining positive and negative terminals connect to the amplifier. This configuration increases the total impedance (e.g., two 4 Ω coils in series result in 8 Ω).
- Kableatu paraleloa: Connect both positive terminals together and both negative terminals together. These combined terminals then connect to the amplifier. This configuration decreases the total impedance (e.g., two 4 Ω coils in parallel result in 2 Ω).
Always use appropriate gauge speaker wire for your power levels to minimize power loss and ensure safe operation. Secure all connections firmly to prevent shorts or loose contacts.

5. Funtzionamendu-argibideak
Behin instalatuta, behar bezala funtzionatzen badu, soinu-kalitate onena bermatzen da eta subwooferraren bizitza luzatzen da.
5.1 Amplifier Ezarpenak
Ezarri zure amplifier's gain (level) control correctly. Start with the gain at its minimum setting and slowly increase it until you hear distortion, then back off slightly. Avoid setting the gain too high, as this can lead to clipping and damage to the subwoofer.
5.2 Gurutzaketa ezarpenak
Erabili zure amplifier's or head unit's low-pass filter (LPF) to send only low frequencies to the subwoofer. A typical crossover point for an 8-inch subwoofer might be between 80 Hz and 120 Hz, but this can vary based on your vehicle's acoustics and personal preference.
5.3 Hasierako Aldia
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 (surround and spider) to loosen up and reach their optimal compliance.
6. Mantentzea
