2. Nga korero haumaru
Kia mau ki nga whakaritenga haumaru e whai ake nei i te wa e whakauru ana me te whakahaere i te ampKaiwhakaora:
- Disconnect the vehicle's battery negative terminal before beginning any installation.
- Me whakarite kia tika te rere o nga waea katoa kia kore ai e pakaru nga taha koi, nga waahanga neke ranei.
- Whakamahia ngā waea hiko me ngā waea whenua e tika ana kia rite ki te wāhanga tāutanga.
- 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.
- A ape i te whakapuru i te amplifier in locations exposed to excessive heat, moisture, or direct sunlight.
- Kaua e whakahaere i te amplifier if it has been exposed to water or other liquids.
- Rapua he āwhina ngaio mēnā kāore koe i te tino mōhio ki tētahi wāhanga o te tukanga tāutanga.
3. Tatūnga me te Tāuta
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. Te Whakamau i te Ampkaikawe
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. Hononga Waea
The HD900/5 utilizes removable power and speaker plugs for simplified wiring. Ensure all connections are secure and properly insulated.
- Te Mana me te Papa: 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.
- Whakauru Tohu: Ko te 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.
- Putanga Tukuoro: Connect your speakers to the designated output terminals. The 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.
- Whakakā Mamao: Connect the remote turn-on lead from your head unit to the amptāuru mamao a liifier.
4. Te whakahaere i te Ampkaikawe
The HD900/5 offers various controls for fine-tuning your audio system's performance.
4.1. Ngā Whakatikatika Whakawhiti
- Tātari Whakawhiti-Tinui Taurangi: 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.
- Tātari Tuku-iti Taurangi: 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.
- Tātari Subsonic: 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. Tiaki
The JL Audio HD900/5 ampHe iti noa te tiaki i te kaipatu. A pee i enei aratohu hei whakarite i tona oranga roa:
- Te horoi: Ia wā horoia te ampHe kakahu ngohengohe, maroke te taha o waho. Kaua e whakamahi i nga matū kino, i nga horoi horoi ranei.
- Whakahau: Me whakarite ko te amplifier's heat sinks are not obstructed. Proper airflow is essential for dissipating heat and maintaining optimal operating temperature.
- Hononga: Tirohia ngā hononga waea katoa i ētahi wā kia mau tonu ai, kia kore ai hoki e waikura.
