JBL 12-inch (305mm) High-Performance Automotive Subwoofer JBLSUBAR12AM Instruction Manual

1. Producte acabatview

The JBL Arena series 12-inch (305mm) automotive subwoofer incorporates Selectable Smart Impedance (SSI) technology and features a design optimized for car audio applications. It utilizes light and agile 2/2.5-inch voice coils within a magnetic gap for linear control of cone excursion. The Symmetrical Field Geometry™ design contributes to linear cone travel and reduced distortion. Construction materials include a cast-aluminum frame, concave cone, nitrile butadiene rubber (NBR) surround, gold-plated speaker-terminal binding posts, a progressive spider, and a vented pole piece. This subwoofer is designed to handle peak power up to 2400 watts (with RMS ratings of 400/700/800 watts depending on model variant), with components engineered for voice coil cooling and sustained output.

Característiques clau

• Unrivaled power handling: Engineered for high power output, capable of handling up to 2400 watts peak power (400/700/800 watts RMS).
• Dual voice coil design: Features dual 2/2.5-inch voice coils suspended in separate magnetic gaps for linear cone control and reduced nonlinearities.
• Die-cast, vented aluminum frame: Provides significant venting and heatsink fins for enhanced power handling and maintains voice coil alignment.
• Composite paper full-edge subwoofer dust cap and cone: Utilizes lightweight and rigid composite paper for efficient air movement without flex or distortion.
• Grilles included.

4. Guia d'instal·lació

Una instal·lació correcta és crucial per a un rendiment i una seguretat òptims. Es recomana fermament que la instal·lació la realitzi un instal·lador professional qualificat d'àudio per a cotxes.

4.1 Precaucions de seguretat

• Desconnecteu el terminal negatiu de la bateria del vehicle abans de començar qualsevol treball elèctric.
• Utilitzeu equips de seguretat adequats, inclosa la protecció ocular.
• Assegureu-vos que tot el cablejat estigui correctament aïllat i fixat per evitar curtcircuits i danys.
• Avoid routing wires near sharp edges or moving parts.

4.2 Connexions de cablejat

The subwoofer requires connection to an external ampvidador. Consulteu el vostre amplifier's manual for specific wiring diagrams and power requirements. General connections include:

• Cable d'alimentació: Connect to the vehicle's positive battery terminal via a fuse (25A fuse included).
• Cable de terra: Connecteu-lo a una superfície metàl·lica neta i sense pintar del xassís del vehicle.
• Cable d'encesa remota: Connecta't al amplifier's remote turn-on input, typically from the head unit.
• Entrada d'àudio: Connecteu el amplifier's speaker output terminals to the subwoofer's gold-plated binding posts. Ensure correct polarity (+ to + and - to -). The dual voice coil design allows for various wiring configurations (series or parallel) to match the amplifier's impedance requirements. Consult a professional for optimal impedance matching.

4.3 Muntatge

The subwoofer is designed for flush mounting. Select a suitable enclosure (not included) that meets the manufacturer's recommended volume specifications for optimal acoustic performance. Secure the subwoofer firmly within the enclosure using appropriate hardware.

• Ensure the mounting location provides adequate clearance for the subwoofer's depth and allows for proper ventilation.
• Avoid mounting in locations exposed to excessive moisture or direct sunlight.

5. Funcionament

Once installed and connected to an amplifier, the subwoofer will reproduce low-frequency audio signals. Adjustments for bass level and crossover frequency are typically made on the connected amplificador o unitat principal.

• Bass Volume Remote Control: Use the included bass volume remote control to adjust the subwoofer's output level conveniently from the driver's seat.
• Configuració de crossover: Set the low-pass filter on your amplifier to prevent higher frequencies from reaching the subwoofer, ensuring clean bass reproduction. A typical starting point is 80-100 Hz.
• Ajust de guany: Carefully adjust the amplifier's gain setting to match the output of your head unit without introducing distortion.

6. Cura i Manteniment

• Neteja: Use a soft, dry cloth to clean the subwoofer cone and frame. Avoid using harsh chemicals or abrasive cleaners.
• Inspecció: Periodically check all wiring connections for tightness and signs of corrosion. Inspect the subwoofer surround for any tears or damage.
• Condicions ambientals: While designed for automotive use, avoid exposing the subwoofer to extreme temperatures or excessive moisture. The product is not waterproof.

7. Solució De Problemes

If you experience issues with your JBL subwoofer, consult the following common troubleshooting steps:

• Sense so:
  • Check all power, ground, and remote turn-on connections. Ensure the fuse is intact.
  • Verifiqueu el amplifier is powered on and receiving an audio signal from the head unit.
  • Confirm speaker wires are correctly connected to both the amplifier and the subwoofer, maintaining proper polarity.
• So distorsionat:
  • Reduir el ampajust de guany del lificador.
  • Check the head unit's volume and bass boost settings; excessive levels can cause distortion.
  • Ensure the subwoofer is not over-excursing (moving too far in and out).
  • Verifiqueu el amplifier is not clipping (indicated by a distortion light on some ampaixecadors).
• Weak Bass Output:
  • Augmentar el amplifier's gain or the bass level on the remote control.
  • Comproveu el amplifier's low-pass filter setting; it might be set too low.
  • Ensure the subwoofer is wired for the correct impedance for your ampmés viu.
