2. Veiligheidsinformatie
WARNING: Failure to follow these safety instructions may result in fire, electric shock, injury, or damage to the product or vehicle.
- Koppel altijd de accu van het voertuig los voordat u elektrische werkzaamheden uitvoert.
- Zorg voor een goede aarding van de ampversterker naar het voertuigchassis.
- Gebruik de juiste draaddikte voor de stroom-, aardings- en luidsprekeraansluitingen om oververhitting en schade te voorkomen.
- Installeer de amplifier in a well-ventilated area to prevent overheating. Avoid mounting in enclosed spaces without adequate airflow.
- Bescherm alle bedrading tegen scherpe randen en bewegende onderdelen.
- Stel de ampbestand tegen vocht of extreme temperaturen.
- Seek professional installation if you are unsure about any part of the setup process.
3. Installatie en installatie
3.1 Montage van de Ampverliezer
Select a mounting location that provides adequate ventilation and is protected from moisture. The amplifier's aluminum heat sink is designed for efficient cooling, but proper airflow is still essential. Secure the ampBevestig de versterker stevig aan een solide ondergrond met behulp van geschikte bevestigingsmaterialen.

Power and Ground Connections:
- +12V (Voeding): Connect to the positive terminal of the vehicle's battery via an appropriate fuse or circuit breaker (not included).
- GND (aarde): Sluit de kabel aan op een schoon, ongelakt metalen oppervlak van het voertuigchassis. Zorg voor een stevige verbinding met lage weerstand.
- REM (op afstand): Sluit de afstandsbedieningsuitgang van uw autoradio aan.

Luidsprekeruitgangsaansluitingen:
- Connect your subwoofer(s) to the "MONO OUTPUT" terminals. Ensure correct polarity (+ to + and - to -).
- De amplifier supports mono operation and is stable down to 1 ohm.
RCA-ingangsaansluitingen:
- Connect the RCA input cables from your head unit's subwoofer output to the amplifier's "INPUT" RCA jacks.

3.3 Eerste inschakeling
After all connections are secure, reconnect the vehicle's battery. The power indicator LED on the amplifier's end panel should illuminate, indicating proper operation. If the protect LED illuminates, refer to the troubleshooting section.
4. Gebruiksaanwijzing
4.1 Bedieningselementen aanpassen
The BG-4000.1D amplifier features several adjustable controls to fine-tune your audio output:
- VERDIENEN: Adjusts the input sensitivity to match the output of your head unit. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion.
- LPF (laagdoorlaatfilter): Controls the upper frequency limit for the subwoofer. Typically set between 40Hz and 180Hz to ensure only low frequencies are sent to the subwoofer.
- SUBSOON: Filters out extremely low frequencies that are inaudible and can damage subwoofers. Typically set between 10Hz and 40Hz.
- FASE: Adjusts the phase of the subwoofer output (0° or 180°) to optimize bass response with other speakers in the vehicle.
- BASVERHOGING: Provides an adjustable bass enhancement (0dB to 12dB) at a specific frequency. Use sparingly to avoid distortion.
4.2 Wired Bass Remote
The included wired bass remote allows for convenient adjustment of the subwoofer output level from the driver's seat. Connect the remote to the dedicated port on the ampbedieningspaneel van de versterker.
4.3 LED-indicatoren
- PWR (Power) LED: Licht groen op wanneer de ampDe versterker is ingeschakeld en werkt normaal.
- PRT (Protect) LED: Brandt rood wanneer de amplifier detects a fault (e.g., overheating, short circuit, low voltage). If this LED lights up, turn off the audio system and investigate the cause.
For optimal performance, refer to the detailed instructions in the full product manual for specific settings and tuning recommendations.
5. Onderhoud
- Schoonmaak: Gebruik een zachte, droge doek om de ampDe buitenkant van de lifier. Gebruik geen agressieve chemicaliën of schurende reinigingsmiddelen.
- Ventilatie: Controleer periodiek of de amplifier's heat sink fins are free from dust and debris to ensure proper cooling.
- Verbindingen: Ensure all power, ground, and speaker connections remain tight and free from corrosion.
6. Probleemoplossing
| Probleem | Mogelijke oorzaak | Oplossing |
|---|---|---|
| Geen stroom (stroom-LED uit) | Doorgebrande zekering, losse stroom-/massa-/remote-draad, geen remote-signaal. | Check fuse, verify all connections are secure, ensure head unit is sending a remote signal. |
| Protect LED is on | Overheating, short circuit in speaker wiring, low impedance load. | Toestaan amplifier to cool, check speaker wiring for shorts, verify speaker impedance is within amplifier's limits. |
| Geen geluidsuitvoer | Loose RCA cables, incorrect gain setting, speaker wires disconnected. | Check RCA connections, adjust gain, verify speaker wire connections. |
| Vervormd geluid | Gain set too high, improper LPF/Subsonic settings, poor quality audio source. | Reduce gain, adjust LPF/Subsonic filters, use a higher quality audio source. |
