The HD900/5 is a high-performance Class D amplifier designed to deliver powerful and clear audio output for your vehicle's sound system. It features a compact design, advanced signal processing capabilities, and robust power delivery for both full-range speakers and subwoofers.
Please read this manual thoroughly before attempting installation or operation to ensure proper setup and to maximize the performance and longevity of your ampaktar ħaj.
2. Informazzjoni dwar is-Sigurtà
Always observe the following safety precautions when installing and operating the ampaktar ħaj:
- Skonnettja t-terminal negattiv tal-batterija tal-vettura qabel tibda kwalunkwe installazzjoni.
- Kun żgur li l-wajers kollha huma mgħoddija u mwaħħlin sew biex tevita ħsara minn truf li jaqtgħu jew partijiet li jiċċaqalqu.
- Uża wajers tal-enerġija u tal-ert tal-kejl xieraq kif speċifikat fit-taqsima tal-installazzjoni.
- Install an external fuse (60-amp recommended) on the main power wire within 18 inches (45 cm) of the battery. The amplifier itself does not have onboard fuses.
- Evita li twaħħal il- amplifier in locations exposed to excessive heat, moisture, or direct sunlight.
- Tħaddimx il- amplifier if it has been exposed to water or other liquids.
- Fittex għajnuna professjonali jekk m'intix ċert dwar xi parti tal-proċess tal-installazzjoni.
3. Setup u Installazzjoni
Proper installation is crucial for optimal performance and reliability. The HD900/5 amplifier is designed for compact installation due to its efficient Class D design.
3.1. Immuntar tal- Ampaktar ħaj
Select a mounting location that provides adequate ventilation and protection from moisture. The amplifier dimensions are approximately 24.89 cm (9.8 inches) W x 10.16 cm (4 inches) H x 34.29 cm (13.5 inches) D. Ensure there is sufficient space around the heat sinks for air circulation.

3.2. Konnessjonijiet tal-Wiring
The HD900/5 utilizes removable power and speaker plugs for simplified wiring. Ensure all connections are secure and properly insulated.
- Qawwa u Art: A 4-gauge power and ground lead is recommended. An external 60-amp in-line fuse is required on the power wire, located close to the battery.
- Inputs tas-Sinjali: Il- amplifier features differential-balanced inputs to minimize noise from the vehicle's electrical system. It accepts both preamp-level (RCA) and speaker-level inputs. A separate adapter may be required for speaker-level input.
- Riżultati tal-Ispeaker: Qabbad l-ispikers tiegħek mat-terminals tal-ħruġ magħżula. Il- amplifier supports various impedance loads:
- Front/Rear Channels: 100 watts RMS x 4 at 4 ohms, or 75 watts RMS x 4 at 1.5-3 ohms. Can be bridged to 150 watts RMS x 2 at 3-6 ohms.
- Subwoofer Channel: 500 watts RMS x 1 at 1.5-4 ohms.
- Tixgħel mill-bogħod: Connect the remote turn-on lead from your head unit to the ampL-input remot tal-lifer.
4. It-tħaddim tal- Ampaktar ħaj
The HD900/5 offers various controls for fine-tuning your audio system's performance.
4.1. Crossover Adjustments
- Filtru Varjabbli High-Pass: Available on the front and rear channels (50-500 Hz, 12 or 24dB/octave). This filter allows you to remove low frequencies from your full-range speakers, improving clarity and protecting them from over-excursion.
- Filtru varjabbli Low-Pass: Available on the subwoofer channel (50-500 Hz, 12 or 24dB/octave). This filter allows only low frequencies to pass to the subwoofer, ensuring it reproduces only the intended bass notes.
- Filtru Subsoniku: On the subwoofer channel (24 dB/octave at 30 Hz). This filter removes extremely low, inaudible frequencies that can waste amplifier power and potentially damage subwoofers.
4.2. Input Sensitivity (Gain)
Adjust the input sensitivity controls to match the output voltage of your head unit. This ensures the amplifier receives an optimal signal without clipping or distortion. Refer to the detailed instructions in the full JL Audio manual for proper gain setting procedures.
4.3. Optional Remote Level Control
An optional wired remote control can be connected to the amplifier for convenient adjustment of the subwoofer channel's level from the driver's seat.
5. Manutenzjoni
The JL Audio HD900/5 ampIl-lifer jeħtieġ manutenzjoni minima. Segwi dawn il-linji gwida biex tiżgura l-lonġevità tiegħu:
- Tindif: Imsaħ perjodikament il- ampNaddaf il-barra tal-lifer b'ċarruta ratba u niexfa. Tużax kimiċi ħarxa jew prodotti tat-tindif li joborxu.
- Ventilazzjoni: Tiżgura li l- amplifier's heat sinks are not obstructed. Proper airflow is essential for dissipating heat and maintaining optimal operating temperature.
- Konnessjonijiet: Occasionally check all wiring connections to ensure they remain secure and free from corrosion.
