Guida all'installazione
Proper installation is crucial for the performance and longevity of your HERTZ DBA 201 subwoofer. Follow these steps carefully:
- Scegli una posizione di montaggio: Select a secure, dry location in your vehicle, such as the trunk or under a seat, that allows for adequate ventilation and does not obstruct vehicle operation. Ensure the subwoofer is firmly mounted to prevent movement during driving.
- Scollegare la batteria: Before making any electrical connections, disconnect the negative (-) terminal of your vehicle's battery to prevent short circuits.
- Cablaggio di alimentazione:
- Connect the main power wire (typically red) from the subwoofer's wiring harness to the positive (+) terminal of the vehicle's battery. Use an appropriate fuse holder (included) as close to the battery as possible.
- Connect the ground wire (typically black) from the subwoofer's wiring harness to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection.
- Connect the remote turn-on wire (typically blue or yellow) to the remote output of your car stereo. If your stereo does not have a remote output, you can use the "Auto Sense" feature (see Operating section).
- Ingresso segnale audio:
- RCA (Low-Level) Input: If your car stereo has RCA pre-outs, connect them to the RCA input jacks on the DBA 201 using the provided RCA cable.
- Input di alto livello: If your car stereo does not have RCA pre-outs, use the high-level input wires from the wiring harness. Connect these wires directly to your car stereo's speaker outputs (e.g., rear left and right speaker wires). Ensure correct polarity.
- Remote Level Control Installation: Mount the remote level control in a convenient location within reach of the driver. Connect its cable to the "REMOTE CONTROL" port on the subwoofer.
- Cablaggio sicuro: Route all wires safely away from moving parts, sharp edges, and heat sources. Use cable ties or clips to secure them.
- Ricollegare la batteria: Once all connections are made and secured, reconnect the negative (-) terminal of the vehicle's battery.

Operazione e regolazioni
After installation, fine-tune your DBA 201 for optimal sound performance using the controls located on the rear panel and the remote level control.
- Ottenere il controllo: Adjusts the input sensitivity of the subwoofer. Start with the gain at minimum and slowly increase it until the subwoofer output matches the rest of your audio system without distortion.
- LO-PASS Filter: This control sets the upper frequency limit for the subwoofer. Adjust it to blend smoothly with your main speakers. A common starting point is between 80Hz and 100Hz.
- AUMENTO DEI BASSI: Provides an adjustable bass equalization at a specific frequency. Use sparingly to avoid distortion.
- FASE (0°/180°): Adjusts the phase of the subwoofer output relative to your main speakers. Experiment with both settings to find the one that provides the most impactful and coherent bass response.
- AUTO TURN ON (REM/DC/AUDIO):
- REM: Uses the remote turn-on wire from your head unit.
- CC: Detects a DC offset on the high-level input to turn on the subwoofer.
- AUDIO: Detects an audio signal on the high-level input to turn on the subwoofer.
- Controllo del livello a distanza: This knob allows you to conveniently adjust the subwoofer's output level from your listening position without accessing the main unit.
