2. Information momba ny fiarovana
WARNING: Failure to follow these safety instructions may result in fire, electric shock, injury, or damage to the product or vehicle.
- Esory foana ny bateria-n'ny fiara alohan'ny hanaovana asa elektrika.
- Hamarino tsara ny fototra iorenan'ny ampfitaovana fanamafisam-peo ho an'ny chassis-n'ny fiara.
- Use appropriate gauge wiring for power, ground, and speaker connections to prevent overheating and damage.
- Install ny amplifier in a well-ventilated area to prevent overheating. Avoid mounting in enclosed spaces without adequate airflow.
- Arovy amin'ny sisiny maranitra sy ny faritra mihetsika ny tariby rehetra.
- Aza sarona ny ampLifier amin'ny hamandoana na hafanana tafahoatra.
- Seek professional installation if you are unsure about any part of the setup process.

Fifandraisana hery sy tany:
- +12V (Hery): Connect to the positive terminal of the vehicle's battery via an appropriate fuse or circuit breaker (not included).
- GND (tany): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid, low-resistance connection.
- REM (lavitra): Ampifandraiso amin'ny output alefa lavitra an'ny head unit-nao.

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

4.1 Fanitsiana ny fanaraha-maso
The BG-4000.1D amplifier features several adjustable controls to fine-tune your audio output:
- MAMPIASA: 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 (Sivana Ambany): Controls the upper frequency limit for the subwoofer. Typically set between 40Hz and 180Hz to ensure only low frequencies are sent to the subwoofer.
- SUBSONIC: Filters out extremely low frequencies that are inaudible and can damage subwoofers. Typically set between 10Hz and 40Hz.
- FASA: Adjusts the phase of the subwoofer output (0° or 180°) to optimize bass response with other speakers in the vehicle.
- BASS BOOST: 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 ampny tontonana fanaraha-maso an'ny lifier.
4.3 LED famantarana
- PWR (Hery) LED: Illuminates green when the ampmandeha sy miasa ara-dalàna ny lifier.
- PRT (Protect) LED: Mamirapiratra mena rehefa ny 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. Fikojakojana
- Fanadiovana: Mampiasà lamba malefaka sy maina hanadiovana ny ampny ivelany amin'ny fitaovana fanadiovana. Aza mampiasa akora simika mahery vaika na mpanadio mikikisana.
- rivotra: Hamarino tsy tapaka fa ny amplifier's heat sink fins are free from dust and debris to ensure proper cooling.
- Fifandraisana: Ensure all power, ground, and speaker connections remain tight and free from corrosion.
