5. Informazioni di sicurezza
Osservate sempre e seguenti precauzioni di sicurezza durante l'installazione è u funziunamentu:
- Disconnect the vehicle's battery negative terminal before starting any electrical work to prevent short circuits.
- Ensure all wiring is correctly routed and secured to prevent damage from moving parts or sharp edges.
- Aduprate un cablaggio di calibru adattatu per a cunnessione di l'alimentazione, di a terra è di l'altoparlanti per gestisce i requisiti di alimentazione di u subwoofer.
- Avoid installing the subwoofer in locations that obstruct vehicle operation or safety features.
- L'esposizione prulungata à livelli elevati di pressione sonora pò causà danni permanenti à l'audizione. Fate attenzione quandu aghjustate u vulume.
- If you are unsure about any part of the installation process, seek professional assistance from a qualified car audio technician.
6. Installazione è Setup
6.1 Selezzione di l'involucru
The DS18 ZR8.4D subwoofer performs well in both sealed and ported enclosures. The choice of enclosure will affect the subwoofer's sound characteristics. Sealed enclosures typically provide tighter, more accurate bass, while ported enclosures can offer louder, deeper bass at specific frequencies. Consult with a car audio specialist or use enclosure design software for optimal results based on your preferences.

6.2 Muntamentu
Ensure the mounting surface is rigid and free from obstructions. Use the provided mounting dimensions:
- Découpe du déflecteur à l'avant : 7.24 pollici / 184 mm
- Profondità di muntatura: 4.4 pollici / 111.4 mm
Pre-drill pilot holes for mounting screws to prevent damage to the enclosure material.
6.3 Wiring the Subwoofer (Dual 4-Ohm Voice Coils)
The ZR8.4D features dual 4-ohm voice coils, offering flexibility in wiring configurations to achieve different impedance loads for your amplifier. Assicuratevi sempre u vostru ampU lifter hè stabile à l'impedenza scelta.
6.3.1 Series Wiring (8-Ohm Load)
To achieve an 8-ohm load, connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then, connect the remaining positive terminal to the amplifier's positive output and the remaining negative terminal to the ampL'output negativu di u lifier.
6.3.2 Parallel Wiring (2-Ohm Load)
To achieve a 2-ohm load, connect both positive terminals of the voice coils together, and connect both negative terminals of the voice coils together. Then, connect the combined positive terminals to the amplifier's positive output and the combined negative terminals to the ampL'output negativu di u lifier.

7. Operating Instructions
7.1 Periodu di rodaggio
Allow a break-in period of approximately 10-20 hours of normal listening before operating the subwoofer at its maximum potential. This allows the suspension components (surround and spider) to loosen up and reach their optimal performance.
7.2 Ampparàmetri di lifier
- Impostazione di guadagnu: Aghjustate u amplifier gain to match the output voltagdi a vostra unità principale. Cuminciate cù u guadagnu à u minimu è aumentatelu pianu pianu finu à sente a distorsione, poi riducete leggermente.
- Low-Pass Crossover (LPF): Impostate l'LPF nant'à u vostru amplifier to filter out high frequencies from the subwoofer. The recommended low-pass crossover frequency for the ZR8.4D is 120 Hz.
- Filtru Subsonicu (HPF): Se u vostru amplifier has a subsonic filter, set it slightly below the tuning frequency of your ported enclosure (if applicable) or around 25-30 Hz for sealed enclosures to protect the subwoofer from over-excursion.
8. Mantenimentu
- Mantene u conu di u subwoofer è u circondu liberi da polvere è detriti. Aduprate un pannu dolce è asciuttu per a pulizia.
- Verificate periodicamente tutti i cunnessione di i fili per assicurassi ch'elli sianu sicuri è senza corrosione.
- Avoid exposing the subwoofer to extreme temperatures or direct sunlight for extended periods.
9. Risoluzione di prublemi
Sè avete prublemi cù u vostru subwoofer, riferitevi à i seguenti passi cumuni di risoluzione di i prublemi:
- Nisun sonu:
- Verificate tutte e cunnessione di putenza, di terra è di accensione remota à u amppiù vivu.
- Verificate u amplifier is receiving an audio signal from the head unit.
- Inspect subwoofer wiring for proper polarity and secure connections.
- Assicurà u amplifier is powered on and not in protection mode.
- Sonu distortu:
- Riduce u amplifier gain setting.
- Check for proper crossover settings; ensure the subwoofer is not playing frequencies too high for its design.
- Verify the subwoofer is not over-driven by the amppiù vivu.
- Inspect the subwoofer cone and surround for any physical damage.
- Weak or Lack of Bass:
- Aumentà u ampguadagnu di vita gradualmente.
- Verificate l'impostazione di fase nantu à u vostru amplifier o unità di testa.
- Ensure the low-pass filter is set correctly (e.g., 120 Hz).
- Verify the enclosure is properly sealed (if applicable) and free from air leaks.
