5. Configurare și instalare
Careful installation is crucial for optimal performance and safety. Plan your wiring and mounting location before beginning.
5.1 Locul de montare
The compact design of the PWE-S8 allows for flexible mounting:
- Under a seat (ensure adequate clearance and ventilation).
- Behind a seat (in trucks or SUVs).
- In the trunk of a sedan.
- In the hatch area of an SUV.
Ensure the chosen location is dry, well-ventilated, and does not interfere with vehicle operation or passenger safety. Secure the unit using the provided mounting hardware.
5.2 Conexiuni de cablare
Follow these general guidelines for wiring. Refer to the detailed wiring diagram in the full owner's manual for specific connections.
- Putere (BATT+): Connect the main power wire directly to the vehicle's positive battery terminal. Use an appropriate gauge wire and install a fuse (not supplied, typically 15A-20A) within 18 inches of the battery.
- Masa (GND): Connect the ground wire to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid electrical connection.
- Pornire de la distanță (REM): Connect this wire to the remote turn-on output of your head unit. This signal turns the subwoofer on and off with your audio system. If your head unit lacks a remote output, some units can use speaker-level input sensing for automatic turn-on.
- Intrare audio:
- Intrare RCA: Connect RCA cables from your head unit's subwoofer pre-out or full-range pre-outs to the RCA INPUTS on the PWE-S8.
- Intrare nivel difuzor: If using speaker-level inputs, connect the vehicle's speaker wires (front or rear) to the SPEAKER LEVEL INPUTS on the PWE-S8 wiring harness.
- Remote Bass Level Control: Connect the provided remote control cable to the REMOTE SUB LEVEL input on the PWE-S8. Mount the control knob in an accessible location for easy adjustment.
6. Operare și reglaje
Once installed, fine-tune the subwoofer's settings for optimal sound integration with your vehicle's audio system.
- Obține controlul: Start with the gain control at its minimum setting. Play music with strong bass and slowly increase the gain until the subwoofer output blends smoothly with your main speakers without distortion. Avoid setting the gain too high, as this can cause clipping and damage.
- LP CROSSOVER Control: Adjust this control to set the upper frequency limit for the subwoofer. A common starting point is between 80Hz and 100Hz. Experiment to find the setting that provides the best blend with your main speakers, ensuring bass notes are localized to the front of the vehicle rather than the subwoofer's location.
- Comutator PHASE: Listen to music with strong bass. Toggle the phase switch between 0° and 180°. Choose the setting that produces the loudest and most impactful bass response. This corrects any phase cancellation issues between the subwoofer and main speakers.
- Remote Bass Level Control: Use this knob to conveniently adjust the subwoofer's output level from your driving position, allowing for on-the-fly adjustments based on music genre or personal preference.
7. Întreținere
