Setup and Installation
Proper installation is crucial for optimal performance and longevity of your subwoofer. It is recommended that installation be performed by a qualified professional.
Enclosure Requirements:
This subwoofer requires a sealed or ported enclosure designed to match its specifications. Consult a car audio specialist or refer to detailed enclosure design guides for optimal performance. Ensure the enclosure provides adequate internal volume and structural integrity to handle the subwoofer's power.
Wiring Connections:
The RAGEXL Series 12" Subwoofer features dual 1-ohm voice coils. This allows for various wiring configurations to achieve different impedance loads (e.g., 0.5 ohm, 2 ohm, or 4 ohm) depending on your amplifier's capabilities. Always ensure your amplifier is stable at the chosen impedance. Use high-quality, appropriately gauged speaker wire for all connections.

- Power Off: Disconnect power from your amplifier and vehicle's battery before making any connections.
- Identify Terminals: Locate the positive (+) and negative (-) terminals for each voice coil on the subwoofer.
- Wire Configuration:
- Parallel Wiring (0.5 Ohm): Connect both positive terminals together and both negative terminals together. Then connect the combined positive to the amplifier's positive output and combined negative to the amplifier's negative output. (Only if amplifier is 0.5 Ohm stable)
- Series Wiring (2 Ohm): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then connect the remaining free positive terminal to the amplifier's positive output and the remaining free negative terminal to the amplifier's negative output.
- Secure Connections: Ensure all wire connections are tight and free from shorts.
- Mounting: Securely mount the subwoofer within its enclosure using appropriate hardware.
Operating Instructions
Once installed, follow these guidelines for safe and effective operation of your B2 Audio RAGEXL subwoofer.
Break-in Period:
Allow a break-in period of approximately 20-30 hours of moderate listening before operating the subwoofer at its maximum potential. This allows the suspension components (surround and spider) to loosen up and reach their optimal compliance.
Amplifier Gain Setting:
Set your amplifier's gain control carefully. Do not use the gain control as a volume knob. It should be set to match the output voltage of your head unit. Improper gain settings can lead to clipping, which can damage the subwoofer.
Crossover and Subsonic Filter:
- Low-Pass Filter (LPF): Set the LPF on your amplifier or head unit to filter out frequencies above the subwoofer's intended range, typically between 60Hz and 80Hz.
- Subsonic Filter (HPF): Utilize a subsonic filter (also known as a high-pass filter for subwoofers) to protect the subwoofer from playing frequencies below its resonant frequency, which can cause over-excursion and damage. A common setting is 20Hz to 25Hz.
Volume Control:
Always listen responsibly. Excessive volume levels can cause hearing damage and may damage your audio equipment. If you notice distortion, reduce the volume immediately.
Maintenance
Regular maintenance helps ensure the longevity and performance of your subwoofer.
- Cleaning: Keep the subwoofer cone and surround free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or excessive moisture.
- Inspection: Periodically inspect the speaker terminals and wiring for any signs of corrosion, loose connections, or fraying.
- Enclosure Check: Ensure the subwoofer enclosure remains sealed and free from air leaks, which can negatively impact performance.
- Temperature Control: Avoid exposing the subwoofer to extreme temperatures or direct sunlight for prolonged periods.
