5. Настройка і ўстаноўка
Proper installation is crucial for performance and safety. If you are not confident in your ability to install this system, please consult a professional installer.
5.1. Мантаж сабвуфера
The G3-12D4 subwoofer requires a suitable enclosure (not included) for optimal performance. Ensure the enclosure is properly sealed and sized according to subwoofer specifications. Mount the subwoofer securely to the enclosure using appropriate screws, ensuring a tight seal around the mounting flange.

5.2. Мантаж Ampзадымнік
Select a mounting location for the WZ3000.1D amplifier that is dry, well-ventilated, and protected from physical damage. Common locations include under a seat, in the trunk, or mounted to a custom amplifier rack. Ensure there is sufficient airflow around the amplifier for cooling. Secure the amplifier firmly using screws.

5.3. Падключэнне сістэмы
Follow these steps carefully for wiring the amplifier and subwoofer:
- Power Cable (Red 4 Gauge): Run the 17 ft. 4 gauge power cable from the vehicle's positive battery terminal to the amplifier location. Install the inline AGU fuse holder within 18 inches (45 cm) of the battery. Do not insert the fuse until all wiring is complete.
- Ground Cable (Black 4 Gauge): Connect the 3 ft. 4 gauge ground cable from the amplifier's ground terminal to a clean, unpainted metal surface on the vehicle chassis. Ensure a solid, low-resistance connection. The ground point should be as short as possible.
- Remote Turn-On Cable (Blue 18 Gauge): Connect the 17 ft. 18 gauge turn-on cable from the amplifier's REM terminal to the remote turn-on output of your head unit. This cable signals the ampЖывільнік уключаецца і выключаецца з дапамогай галаўной прылады.
- RCA Signal Cables: Connect the 17 ft. double shielded RCA cable from the RCA outputs of your head unit to the RCA INPUTs on the WZ3000.1D ampзадымнік.
- Speaker Wiring (16 Gauge): Connect the 20 ft. 16 gauge speaker wire from the amplifier's speaker output terminals to the G3-12D4 subwoofer. Ensure correct polarity (+ to + and - to -). For a single G3-12D4 (dual 4-ohm voice coils), you can wire the voice coils in parallel for a 2-ohm load or in series for an 8-ohm load. The WZ3000.1D amplifier is stable down to 1 ohm, so a 2-ohm parallel configuration is recommended for maximum power output.
- Пульт дыстанцыйнага кіравання басамі: Connect the remote bass control knob to the dedicated REMOTE port on the amplifier. Mount the knob in an accessible location for easy adjustment.

5.4. Канчатковае падключэнне
Once all wiring is securely connected and checked for shorts, insert the appropriate fuse (80A or 100A, depending on your system's power draw) into the inline AGU fuse holder near the battery. Reconnect the vehicle's negative battery terminal.
6. Інструкцыя па эксплуатацыі
After installation, power on your head unit. The amplifier should turn on automatically (indicated by a power LED). Adjust the amplifier settings as follows:
- GAIN (Узровень уваходнага сігналу): Start with the GAIN control at minimum. Play a familiar track with strong bass at about 75% of your head unit's maximum volume. Slowly increase the GAIN until you hear distortion, then back off slightly. This sets the ampУсталюйце ўваходную адчувальнасць налады ў адпаведнасці з выхадным сігналам вашай галаўной прылады.
- ФНЧ (фільтр нізкіх частот): This control filters out high frequencies, allowing only low frequencies to pass to the subwoofer. Set the LPF between 40 Hz and 180 Hz. A common starting point is 80 Hz, but adjust to blend smoothly with your main speakers.
- Дагукавы фільтр: This filter removes extremely low frequencies below the audible range that can cause damage to the subwoofer. Set it between 0 Hz and 50 Hz. A setting around 25-30 Hz is often suitable for ported enclosures, while sealed enclosures may not require it as much.
- BASS BOOST FREQ: This selects the frequency at which the bass boost will be applied. Adjust this to enhance a specific bass frequency range.
- УЗмацненне баса: This control increases the output level at the selected bass boost frequency (0-12 dB). Use sparingly to avoid distortion and potential speaker damage.
- Пульт дыстанцыйнага кіравання басамі: This knob allows you to adjust the subwoofer's output level conveniently from your listening position without affecting other ampналады lifier.
7. Тэхнічнае абслугоўванне
To ensure longevity and optimal performance of your car audio system:
- Рэгулярна правярайце ўсе злучэнні правадоў на надзейнасць і наяўнасць карозіі.
- Трымайце amplifier and subwoofer free from dust and debris. Use a soft, dry cloth for cleaning.
- Забяспечце amplifier's cooling fins are not obstructed to prevent overheating.
- Avoid exposing the subwoofer cone to direct sunlight for extended periods, as UV rays can degrade materials.
