4. Setup and Installation

Proper installation is crucial for optimal performance and safety. It is highly recommended that installation be performed by a qualified car audio professional. If you choose to install it yourself, please follow these general guidelines carefully.

4.1 Safety Precautions

• Disconnect the vehicle's negative battery terminal before starting any wiring.
• Ensure all wiring is properly insulated and secured to prevent short circuits.
• Use appropriate gauge wiring for power and speaker connections.
• Mount the subwoofer securely to prevent movement during vehicle operation.

4.2 Wiring Connections

1. Power Wiring: Connect a suitable gauge power wire from the vehicle's positive battery terminal to your amplifier's +12V input. An in-line fuse should be installed within 18 inches of the battery.
2. Ground Wiring: Connect a short, heavy gauge ground wire from your amplifier's GND input to a clean, unpainted metal surface on the vehicle's chassis.
3. Remote Turn-On: Connect a remote turn-on wire from your head unit (or other switched 12V source) to your amplifier's REM input.
4. Speaker Wiring: Connect the speaker wires from your amplifier's output terminals to the input terminals on the BNPS102 enclosure. Ensure correct polarity (+ to + and - to -). The BNPS102 has a 1 Ohm impedance.
5. Neon Lighting Power: The integrated neon accent lighting requires a separate power connection. Connect the provided power cord for the neon lights to a suitable 12V power source in your vehicle, ensuring it is fused. The remote control operates the lighting.

5. Operating Instructions

Once the BNPS102 system is properly installed and connected to a compatible amplifier, you can begin operating it.

5.1 Amplifier Settings

• Gain Control: Adjust the amplifier's gain control to match the output voltage of your head unit. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly.
• Low-Pass Filter (LPF): Set the amplifier's LPF to a frequency typically between 80Hz and 120Hz. This ensures that only low frequencies are sent to the subwoofer, preventing distortion and improving sound quality.
• Bass Boost: Use the bass boost feature sparingly, if at all. Excessive bass boost can lead to distortion and potential damage to the subwoofers.
• Subsonic Filter: If your amplifier has a subsonic filter, set it to around 25-30Hz to protect the subwoofers from playing frequencies too low for their design.

5.2 Neon Accent Lighting

The BNPS102 features built-in neon accent lighting. This lighting is controlled via the included remote control. Ensure the lighting power cord is connected to a 12V source. Refer to the remote control's specific instructions for changing colors, patterns, or turning the lights on/off.

6. Maintenance

Regular maintenance will help ensure the longevity and performance of your Pyramid BNPS102 system.

• Cleaning: Use a soft, dry cloth to wipe down the enclosure and plexiglass window. Avoid abrasive cleaners or solvents that could damage the finish or materials.
• Inspection: Periodically check all wiring connections to ensure they are secure and free from corrosion. Inspect the speaker cones and surrounds for any signs of damage or wear.
• Ventilation: Ensure the subwoofer enclosure has adequate ventilation, especially around the ports, to prevent overheating of the internal components.
• Environmental Conditions: Avoid exposing the system to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture.
