The JBL Basspro Hub is designed for installation within the spare tire well of your vehicle. Follow these general steps for proper setup. Professional installation is recommended.
4.1. Placement
Position the Basspro Hub securely in the center of your vehicle's spare tire. Ensure it fits without obstruction and can be fastened using the provided hardware. The unit's dimensions are 14-3/16" (360mm) diameter and 6-1/2" (165mm) height.

4.2. Wiring Connections
Connect the wiring harness to the subwoofer and route the cables to the appropriate locations in your vehicle. Ensure all connections are secure and insulated.
- Power (B+): Connect the main power wire directly to the positive terminal of the vehicle's battery. Use an appropriate fuse (not supplied, typically 30A) as close to the battery as possible.
- Ground (GND): Connect the ground wire to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid electrical connection.
- Remote Turn-On (REM): Connect this wire to the remote output of your head unit or an ignition-switched 12V source. This signal turns the subwoofer on and off with your vehicle's audio system.
- Audio Input: Connect the audio signal from your head unit. The Basspro Hub supports both low-level (RCA) and high-level (speaker wire) inputs. Use the appropriate input method for your head unit.
- Remote Control: Plug the wired remote controller into the designated port on the subwoofer. Route the cable to a convenient location for adjustment.

5. Operating the Subwoofer
The included wired remote control provides convenient access to key adjustments for optimizing the subwoofer's performance within your vehicle's audio system.
5.1. Remote Control Functions
- Gain: This knob adjusts the overall output level of the subwoofer. Start with a low setting and gradually increase until the bass blends smoothly with your main speakers without overpowering them.
- Bass Boost: Provides an additional boost to bass frequencies, ranging from 0 to 12dB at a fixed frequency of 50 Hz. Use this to enhance low-end impact as desired.
- Low Pass Filter (LPF): This control sets the upper frequency limit for the subwoofer. Frequencies above this setting will be filtered out, ensuring the subwoofer only reproduces low-frequency sounds. Adjust this to match the low-frequency capabilities of your main speakers.
- Phase: The phase button (0° or 180°) adjusts the subwoofer's output phase relative to your main speakers. If the bass sounds weak or out of sync, try switching the phase to achieve better integration and impact.
6. Maintenance
To ensure the longevity and optimal performance of your JBL Basspro Hub, follow these simple maintenance guidelines:
- Cleaning: Keep the subwoofer clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive cleaners.
- Connection Inspection: Periodically inspect all wiring connections (power, ground, remote, audio input) to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
- Ventilation: Ensure the subwoofer has adequate ventilation, even when installed in the spare tire well, to prevent overheating.
7. Troubleshooting
If you experience issues with your JBL Basspro Hub, refer to the following troubleshooting guide before contacting customer support.
| Problem | Possible Cause | Solution |
