Enstriksyon Sekirite
To prevent injury or damage to the amplifier, vehicle, or other property, please observe the following safety precautions:
- Enstalasyon pwofesyonèl rekòmande: Installation of car audio components requires experience with electrical wiring and vehicle systems. If you are unsure, consult a professional installer.
- Dekonekte batri: Toujou dekonekte tèminal negatif batri machin nan anvan ou kòmanse nenpòt travay elektrik pou evite kous kout.
- Bon vantilasyon: Asire w la amplifier is mounted in a location with adequate airflow to prevent overheating. Do not cover the heatsink.
- Montaj sekirite: Monte la amplifier securely to prevent it from coming loose during vehicle operation or in the event of a collision.
- Fil elektrik kòrèk: Use appropriate gauge wiring for power, ground, and speaker connections as specified in the installation section. Incorrect wiring can cause damage or fire.
- Evite imidite: Pa ekspoze a amplifier a imidite oswa tanperati ekstrèm.
- Pwoteksyon Fuse: Always use the correct fuse rating as specified for the amplifier.
Enstalasyon ak Enstalasyon
Careful planning and execution are crucial for optimal performance and safety. Follow these general guidelines for installation.
Kote montaj
Choose a dry, well-ventilated location away from direct sunlight and heat sources. Ensure sufficient space around the amplifier for air circulation. Common locations include under seats, in the trunk, or behind rear seats.
Koneksyon fil elektrik
Refer to the diagram below for connection points. Ensure all connections are tight and secure to prevent power loss or short circuits.

Koneksyon pouvwa (+12V)
Connect a heavy-gauge power cable (e.g., 4 AWG or larger, depending on cable length and system power requirements) directly from the vehicle's positive battery terminal to the +12V terminal on the amplifier. Install an inline fuse holder within 18 inches (45 cm) of the battery, using a fuse rated appropriately for the amplifier (refer to specifications for total fuse rating).
Koneksyon tè (GND)
Connect a heavy-gauge ground cable (same gauge as power cable) from the GND terminal on the amplifier to a clean, unpainted metal point on the vehicle's chassis. Ensure a solid, low-resistance connection. Sand away any paint or rust from the contact point.
Aktivite a Distans (REM)
Connect a remote turn-on wire (typically 18 AWG) from your head unit's remote output to the REM terminal on the amplifizè. Fil sa a siyalize amplifier to turn on when the head unit is powered on.
Note: The GZIA 1.1500D features a high-level input with an auto-on function. If using high-level inputs, the remote wire connection may not be necessary as the amplifier can detect an audio signal and turn on automatically.
Speaker Connection (SPEAKER)
Connect your subwoofer(s) to the SPEAKER terminals. This is a mono amplifier, so ensure your speakers are wired to present a stable impedance to the amplifier (minimum 1 Ohm). Observe correct polarity (+ to + and - to -) for optimal sound.
Input Connection (INPUT)
Antre RCA: Connect RCA cables from your head unit's pre-out (subwoofer or full-range) to the RCA INPUT terminals on the amplifier.
Antre wo nivo: If your head unit does not have RCA outputs, use the included high-level adapter cable to connect to your head unit's speaker outputs. Connect the speaker wires from the head unit to the high-level input connector, then plug the connector into the HI INPUT (AUTO ON) port on the amplifier.
Initial Setup and Adjustments
After all connections are made, double-check your wiring before reconnecting the vehicle's battery. Once powered on, proceed with the following adjustments:
- Akeri kontwòl: Start with the GAIN control at minimum. Play a familiar track and slowly increase the gain until you hear distortion, then back off slightly. This matches the amplifier's input sensitivity to your head unit's output.
- LPF (Filtè ki ba pase): Adjust the LPF to filter out frequencies above your subwoofer's operating range. A common starting point is 80-100 Hz.
- Bass ranfòse: Use the BASS BOOST control sparingly. Excessive bass boost can cause distortion and damage to speakers.
- Faz: Adjust the PHASE switch (0° or 180°) to achieve the best bass response and integration with your front speakers. Listen for the strongest, most impactful bass.
Opere a Amplifier
Yon fwa enstale epi konfigire, la amplifier operates automatically with your vehicle's audio system. The POWER indicator light will illuminate when the amplifier is on. If the PROTECT light illuminates, it indicates a fault condition (e.g., short circuit, overheating, low voltage). Refer to the troubleshooting section.
