4.2.1 Cunnessione di putenza
- Connect the power cable (typically red) from the amplifier's +12V terminal to the positive terminal of the vehicle's battery.
- Install the fuse holder within 18 inches (45 cm) of the battery and insert the appropriate fuse (refer to specifications for fuse rating).
4.2.2 Cunnessione in terra
- Cunnette u cavu di terra (tipicamente neru) da u amplifier's GND terminal to a clean, unpainted metal surface on the vehicle's chassis.
- Ensure the ground point is free of paint, rust, or dirt for a good electrical connection. The ground cable should be as short as possible, ideally less than 3 feet (1 meter).
4.2.3 Remote Turn-On Connection
- Cunnette u filu di accensione remota (tipicamente blu) da u amplifier's REM terminal to the remote output of your head unit. This wire turns the ampaccende è spegne u lifer cù u sistema audio di a vostra vittura.
4.2.4 Input Connection (RCA or Speaker Level)
- Input RCA: Sè a vostra unità principale hà pre-outs RCA, cunnetteli à amplifier's RCA INPUT terminals (CH-1(L) and CH-2(R)).
- Ingressu di livellu di l'altoparlante: If your head unit does not have RCA pre-outs, use the speaker level input harness. Connect the speaker wires from your head unit's speaker outputs to the corresponding wires on the amplifier's speaker level input harness.

5. Operating Instructions
Una volta installatu, aghjustate u ampparàmetri di lifier per una prestazione sonora ottimale.
5.1 Cuntrolli è Ajustamenti
- GAIN: This control matches the output level of your head unit to the input sensitivity of the amplifier. Start with the gain set to minimum, then slowly increase it until you achieve a clear, undistorted sound at your desired maximum volume from the head unit. Avoid setting the gain too high, as this can introduce distortion.
- LP FILTER (Low Pass Filter): Stu cuntrollu stabilisce u limite di frequenza superiore per u amplifier's output. For subwoofers, set this to a frequency typically between 50Hz and 120Hz. This ensures that only low-frequency sounds are sent to the subwoofer, improving overall sound clarity.
- EQ BASS: This control provides a bass boost at a specific frequency. Use sparingly and adjust carefully to avoid distortion or damage to your subwoofer.
- REMOTE BASS CONTROL: If connected, this allows for convenient adjustment of the bass level from the driver's seat.
6. Mantenimentu
- Pulizia: Asciugà periodicamente u ampL'esternu di u lifizer cù un pannu dolce è asciuttu. Ùn aduprate micca prudutti chimichi aggressivi o detergenti abrasivi.
- Cuntrolli di cunnessione: Regularly inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
- Sostituzione di fusible: Se u amplifier stops working, check the fuse in the external fuse holder. Replace it only with a fuse of the exact same type and rating. Never use a higher-rated fuse.
