2. Nøkkelfunksjoner

• 900W RMS Power Handling: Designed to pair effectively with high-power amplifiers, such as the X-Series X-A90M 900W mono amplivligere.
• 24mm Linear Xmax (1-way): Allows for significant cone excursion, contributing to deep and impactful bass.
• Dual Spiders: Provides precise control over the large dynamic range of the subwoofer's movement.
• Dual Shorting Rings: Ensures strong motor control, reducing total harmonic distortion (THD) and producing tight bass.
• Center Pole Radial Heat Sink: Efficiently dissipates heat from the voice coil, ensuring long-term high output and reliability.
• HAMR Surround: The High-Amplitude Multi-Roll surround allows for linear cone movement across its large excursion range.
• Pulp/Mica Cone: Light yet rigid cone material for accurate bass with natural tone.
• Twist-lock Trim Ring with Full Mesh Grill: Included for protection and a clean aesthetic.

3. Oppsett og installasjon

Proper installation is crucial for optimal performance and longevity of your subwoofer. It is highly recommended that installation be performed by a qualified professional. Ensure all connections are secure and correctly polarized to prevent damage to the subwoofer or amplivligere.

3.1 Kablingstilkoblinger

The X-W10D4 features dual 4-ohm voice coils, offering flexibility in wiring configurations (series or parallel) to achieve the desired impedance for your ampleverandør. Se din amplifier's specifications for compatible impedance loads.

• Serie ledninger: Connect the positive terminal of VC1 to the negative terminal of VC2. Connect the remaining negative terminal of VC1 and positive terminal of VC2 to the amplifier. This results in an 8-ohm load.
• Parallell ledning: Connect the positive terminals of VC1 and VC2 together. Connect the negative terminals of VC1 and VC2 together. Connect these combined positive and negative terminals to the amplifier. This results in a 2-ohm load.

3.2 Krav til innkapsling

The performance of the subwoofer is highly dependent on the enclosure design. Consult Alpine's official documentation or a car audio specialist for recommended sealed or ported enclosure volumes and dimensions to achieve optimal sound quality and output.

4. Bruksanvisning

Once installed, proper tuning of your amplifier and head unit settings is essential for optimal subwoofer performance and system longevity.

• Gevinstinnstilling: Still inn ampforsterkningen riktig for å matche utgangsvolumettage of your head unit. Avoid setting the gain too high, as this can lead to distortion and potential damage to the subwoofer.
• Crossover-innstillinger: Utilize the low-pass filter (LPF) on your amplifier or head unit to send only low frequencies to the subwoofer. A typical LPF setting for a 10-inch subwoofer might be between 60Hz and 80Hz, but this can vary based on your full-range speakers and personal preference.
• Subsonisk filter: Hvis din amplifier has a subsonic filter, engage it to protect the subwoofer from playing frequencies below its resonant frequency, which can cause excessive excursion and potential damage.
• Innkjøringsperiode: Allow for a break-in period of several hours of moderate listening before operating the subwoofer at its maximum capabilities. This allows the suspension components to loosen and perform optimally.

5. Vedlikehold

The Alpine X-W10D4 is designed for durability and requires minimal maintenance. Follow these guidelines to ensure its longevity:

• Rengjøring: Use a soft, dry cloth to gently wipe away dust from the cone and surround. Avoid using harsh chemicals or excessive moisture.
• Miljøvern: Ensure the subwoofer is installed in an environment protected from direct sunlight, extreme temperatures, and excessive moisture.
• Undersøkelse: Periodically check wiring connections for tightness and inspect the subwoofer for any signs of physical damage.

6. Feilsøking

Hvis du opplever problemer med subwooferen, kan du se følgende vanlige feilsøkingstrinn:

• Ingen lyd:
  • Check all power, ground, and remote turn-on connections to the amplivligere.
  • Verify the RCA signal cables are securely connected to both the head unit and amplivligere.
  • Sørg for at amplifier is powered on (check its power indicator light).
  • Bekreft at subwooferledningene er riktig koblet til ampvarmeklemmer.
• Forvrengt lyd:
  • Reduser ampInnstilling av forsterkningsfaktor.
  • Check the head unit's volume level and bass boost settings; avoid excessive boosting.
  • Ensure the LPF (low-pass filter) is set appropriately and not too high.
  • Inspiser subwoofermembranen og surroundhøyttaleren for fysisk skade.
• Overoppheting av subwoofer:
  • Sørg for at amplifier's impedance load matches the subwoofer's wiring configuration.
  • Verify proper ventilation around the amplivligere.
  • Reduce prolonged high-volume playback.

If these steps do not resolve the issue, consult a professional car audio technician or contact Alpine customer support.
