5.2 රැහැන් සම්බන්ධතා
Follow these general guidelines for wiring. Refer to the detailed wiring diagram in the full owner's manual for specific connections.
- බලය (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.
- බිම (GND): වාහන චැසියේ පිරිසිදු, තීන්ත ආලේප නොකළ ලෝහ මතුපිටකට බිම් වයරය සම්බන්ධ කරන්න. ඝන විදුලි සම්බන්ධතාවයක් සහතික කර ගන්න.
- දුරස්ථ සක්රිය කිරීම (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.
- ශ්රව්ය ආදානය:
- RCA ආදානය: Connect RCA cables from your head unit's subwoofer pre-out or full-range pre-outs to the RCA INPUTS on the PWE-S8.
- කථික මට්ටමේ ආදානය: 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.
- දුරස්ථ බාස් මට්ටමේ පාලනය: 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. මෙහෙයුම් සහ ගැලපීම්
Once installed, fine-tune the subwoofer's settings for optimal sound integration with your vehicle's audio system.
- පාලනය ලබා: 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.
- PHASE ස්විචය: 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.
- දුරස්ථ බාස් මට්ටමේ පාලනය: 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. නඩත්තු කිරීම
The Alpine PWE-S8 requires minimal maintenance to ensure long-lasting performance.
- පිරිසිදු කිරීම: Use a soft, dry cloth to wipe the exterior of the unit. Do not use harsh chemicals or abrasive cleaners.
