The compact design of the NB-3000 allows for flexible placement. Common locations include:

• Under a car seat (ensure adequate clearance and ventilation).
• ట్రంక్ లో.

4.2. వైరింగ్ కనెక్షన్లు

ఏదైనా కనెక్షన్లు చేసే ముందు, వాహనం యొక్క బ్యాటరీ నెగటివ్ టెర్మినల్ డిస్‌కనెక్ట్ చేయబడిందని నిర్ధారించుకోండి.

1. Power Connection (BATT+): Connect a suitable gauge power cable (e.g., 8 AWG or 10 AWG, depending on cable length and power requirements) directly from the vehicle's positive battery terminal to the "POWER" terminal on the subwoofer's high-level input connector. Install an in-line fuse (e.g., 20A-30A) within 18 inches (45 cm) of the battery.
2. గ్రౌండ్ కనెక్షన్ (GND): Connect a short, heavy gauge ground cable (same gauge as power cable) from the "GND" terminal on the subwoofer's high-level input connector to a clean, unpainted metal surface of the vehicle chassis. Ensure a good electrical contact.
3. రిమోట్ టర్న్-ఆన్ (REM): Connect a remote turn-on wire from your car stereo's remote output (usually a blue/white wire) to the "REM" terminal on the subwoofer's high-level input connector. This wire tells the subwoofer to turn on and off with your car stereo. If your stereo does not have a remote output, you may need to use an ignition-switched 12V source.
4. ఆడియో ఇన్‌పుట్:
   • తక్కువ-స్థాయి ఇన్‌పుట్ (RCA): If your car stereo has RCA pre-outs, connect RCA cables from the stereo's subwoofer or rear pre-outs to the "CH1" and "CH2" RCA inputs on the subwoofer.
   • ఉన్నత-స్థాయి ఇన్‌పుట్: If your car stereo does not have RCA pre-outs, connect the speaker wires from your stereo's rear speakers to the "HIGH LEVEL INPUT" terminals on the subwoofer's connector. Ensure correct polarity (+ to + and - to -).
5. రిమోట్ స్థాయి నియంత్రణ: Connect the wired remote control cable to the "REMOTE" port on the subwoofer's control panel. Mount the remote control in a convenient location for the driver.

అన్ని కనెక్షన్లు చేసిన తర్వాత, వాహనం యొక్క నెగటివ్ బ్యాటరీ టెర్మినల్‌ను తిరిగి కనెక్ట్ చేయండి.

5. ఆపరేటింగ్ సూచనలు

Once installed, you can adjust the subwoofer's settings for optimal sound.

5.1. ప్రారంభ పవర్-అప్

Turn on your car stereo. The "POWER" indicator light on the subwoofer's control panel should illuminate (green). If the "PROTECT" light (red) illuminates, there may be a wiring issue or fault. Refer to the Troubleshooting section.

5.2. సర్దుబాటు నియంత్రణలు

• GAIN (MIN/MAX): This knob controls the input sensitivity. Start with the GAIN set to minimum (MIN). Play music with a moderate bass level. Slowly increase the GAIN until the bass output blends well with your main speakers without distortion. Avoid setting the GAIN too high, as this can cause distortion and damage.
• FREQ (ఫ్రీక్వెన్సీ): This knob adjusts the low-pass filter (LPF) crossover frequency, typically from 50Hz to 160Hz. The LPF ensures that only low frequencies are sent to the subwoofer. Adjust this to blend smoothly with your main speakers. A common starting point is around 80-100Hz.
• దశ (0°/180°): This switch adjusts the phase of the subwoofer's output relative to your main speakers. Listen to music with strong bass and switch between 0° and 180°. Choose the setting that provides the most impactful and cohesive bass response.
• REMOTE (Level Control): The wired remote control allows you to conveniently adjust the subwoofer's output level from the driver's seat without accessing the main unit.
