Setup and Installation
Proper installation is crucial for the performance and longevity of your subwoofer. It is recommended that installation be performed by a qualified professional.
Unpacking
Carefully remove the subwoofer from its packaging. Inspect the unit for any signs of damage during transit. Retain all packaging materials for future use or in case of return.

Mounting Considerations
The Rave 12 subwoofer features a shallow mounting depth of approximately 5.5 inches, making it suitable for installations where space is limited, such as behind truck seats or in compact enclosures. Ensure adequate clearance for the subwoofer's excursion within the chosen enclosure.

Wiring Configurations
The subwoofer features Dual 4 Ohm Voice Coils, offering flexibility in wiring. You can wire a single subwoofer for a 2 Ohm or 8 Ohm load. For multiple subwoofers, further configurations are possible to achieve 1 Ohm or other desired impedances. Consult an impedance wiring diagram for specific setups.

Enclosure Recommendations
For optimal performance, the B2 Audio Rave 12 is recommended for compact ported enclosures with an internal volume between 1.5 and 1.77 cubic feet. While it can operate in sealed enclosures, a ported design will maximize its bass output. The subwoofer's design includes a thick plastic ring to prevent the surround from hitting the enclosure in shallow-mount applications.

Operating Instructions
Once installed, ensure your amplifier is properly configured to match the subwoofer's impedance and power handling. Start with low volume levels and gradually increase to allow the subwoofer to break in. Avoid overdriving the subwoofer, which can lead to distortion and damage.
Amplifier Matching
Match your amplifier's RMS output to the subwoofer's 500W RMS rating. Ensure the amplifier's impedance output matches the wired impedance of your subwoofer(s) (e.g., 2 Ohm or 8 Ohm for a single subwoofer). Incorrect impedance matching can lead to amplifier overheating or reduced power output.
Crossover Settings
Set your low-pass filter (LPF) on your amplifier or head unit to prevent high frequencies from reaching the subwoofer. A typical range for subwoofers is between 80Hz and 120Hz. Adjust to your preference and system acoustics.
Gain Adjustment
Set the amplifier gain correctly to prevent clipping and distortion. This is not a volume control; it matches the output voltage of your head unit to the input sensitivity of your amplifier. Consult your amplifier's manual for proper gain setting procedures.
Maintenance
The B2 Audio Rave 12 subwoofer is designed for durability. Regular maintenance is minimal but important for long-term performance.
- 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 check the wiring connections at the push terminals to ensure they are secure. Inspect the surround for any signs of cracking or damage.
- Environment: Avoid exposing the subwoofer to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture, as it is not water resistant.
Troubleshooting
If you experience issues with your subwoofer, refer to the following common troubleshooting steps:
- No Sound:
- Check all wiring connections from the amplifier to the subwoofer.
- Verify the amplifier is powered on and receiving a signal.
- Ensure the head unit is sending an audio signal to the amplifier.
- Confirm correct impedance matching between the subwoofer and amplifier.
- Distorted Sound:
- Reduce the amplifier gain setting.
- Check for proper crossover settings.
- Ensure the subwoofer is not overdriven (volume too high).
- Inspect the subwoofer cone and surround for physical damage.
- Weak Bass:
- Verify amplifier gain and crossover settings.
- Check for correct wiring polarity.
- Ensure the enclosure volume matches recommended specifications.
If problems persist after following these steps, contact B2 Audio USA customer support or a qualified car audio technician.
