Ensure the chosen location allows for adequate ventilation and does not interfere with vehicle operation or passenger safety. Use the provided mounting screws and Velcro to secure the unit firmly.
5.2 Ožičenje
Follow the wiring diagram carefully. Incorrect wiring can damage the unit or your vehicle's electrical system.
- Priključak za napajanje (+12V): Connect the power cable (red) to the positive terminal of your vehicle's battery. Install the included fuse holder as close to the battery as possible.
- Uzemljenje (GND): Connect the ground cable (black) to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection.
- Daljinsko uključivanje (REM): Connect the remote turn-on cable (blue) to the remote output of your car stereo. This will turn the subwoofer on and off with your stereo. If your stereo does not have a remote output, you can connect it to an accessory wire that turns on with the ignition.
- Audio ulaz:
- Ulaz niskog nivoa (RCA): If your car stereo has RCA pre-outs, connect them to the "LOW LEVEL" RCA inputs on the subwoofer using the provided RCA cables.
- Ulaz visokog nivoa: If your car stereo does not have RCA pre-outs, use the provided High to Low Level Converter. Connect your stereo's speaker outputs to the converter, then connect the converter's output to the "HIGH LEVEL" input on the subwoofer.
- Daljinska kontrola basa: Connect the wired volume controller to the "REMOTE CONTROL" port on the subwoofer. Mount the controller in an accessible location for easy adjustment.

Figure 6.1: Subwoofer control panel with adjustment knobs.
- DOBITAK: Adjusts the input sensitivity. Start with the gain at minimum and slowly increase it until the desired volume is achieved without distortion.
- NISKI FILTER (LPF): Controls the upper frequency limit of the subwoofer. Adjust between 50Hz and 150Hz. A common setting is around 80-100Hz, but this can be adjusted to blend with your main speakers.
- BASS BOOST: Provides an adjustable bass enhancement at 45Hz, from 0 to 12dB. Use sparingly to avoid distortion.
- FAZA: Switches the subwoofer's output phase between 0° and 180°. Adjust this to match the phase of your main speakers for optimal bass response. Listen to music and switch between 0° and 180° to find the setting that produces the strongest and most coherent bass.
- DALJINSKO UPRAVLJANJE: The wired remote allows for convenient adjustment of the subwoofer's output level from the driver's seat.

| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| No Power / No LED | Pregoreni osigurač, loša veza sa napajanjem/uzemljenjem, nema daljinskog signala. | Check fuse, verify power and ground connections, ensure remote wire is connected and receiving +12V when stereo is on. |
| Nema zvuka | Low gain setting, incorrect audio input connection, damaged RCA cables, stereo output issues. | Increase gain, check RCA or high-level input connections, test cables, ensure stereo is outputting audio. |
| Distorted Sound | Gain set too high, bass boost too high, incorrect LPF setting, poor quality audio source. | Reduce gain, lower bass boost, adjust LPF, use a higher quality audio source. |
| Subwoofer Overheats (Red LED) | Insufficient ventilation, prolonged high volume, impedance mismatch. | Ensure adequate airflow around the unit, reduce volume, check wiring for short circuits. Allow unit to cool down. |
| Slab bas | Phase mismatch, low gain, incorrect LPF, poor mounting. | Adjust phase switch, increase gain, adjust LPF, ensure subwoofer is securely mounted. |
