4. Setup and Installation
Proper installation ensures optimal performance and safety. Follow these steps for installing your Xtenzi XTBR14 bass remote.
4.1. Amplifier Gain Setting
Before connecting the remote, it is essential to set your amplifier's internal gain. The XTBR14 functions as a secondary gain control and will not increase the amplifier's internal gain setting. Its purpose is to allow you to reduce bass levels as desired, helping to protect your system from square waves and distortion. Set your amplifier's gains for maximum bass levels first, then use the XTBR14 for fine-tuning.

This diagram illustrates the connection of the XTBR14 remote knob between a head unit and an amplifier. It emphasizes the importance of setting the amplifier's internal gain first, explaining that the XTBR will not increase the internal gain setting but allows for bass reduction as desired.
4.2. Remote Installation
- Choose a Location: Select a convenient location for the bass knob that is easily accessible from the driver's seat but out of the way. Common installation spots include unused dash locations, inside the center console, or on the trim panel below the steering wheel. Some models can be flush-mounted, while others are designed for surface mounting with the entire box visible.
- Route the Cable: Route the 5-meter (16-foot) long connection cable from your chosen remote location to the amplifier. Ensure the cable is routed safely, away from moving parts, heat sources, and potential pinch points.
- Connect to Amplifier: Connect one end of the RJ45 8-pin cable to the amplifier's dedicated 'REMOTE LEVEL PORT' connector.
- Connect to Remote: Connect the other end of the RJ45 8-pin cable to the port on the XTBR14 remote unit.
- Secure the Remote: Use the provided mounting screws to securely fasten the XTBR14 remote unit in your chosen location.

Note: Plugging in the remote bass control overrides the BASS EQ Control on the amplifier's side panel.
5. Operating Instructions
Once installed, the XTBR14 allows for easy adjustment of your amplifier's bass output. Simply turn the knob clockwise to increase the bass level or counter-clockwise to decrease it. This provides on-the-fly control over your audio system's bass response from your driving position.
6. Maintenance
The Xtenzi XTBR14 requires minimal maintenance. Keep the unit clean and free from dust and debris. Avoid exposing it to excessive moisture or extreme temperatures. Ensure the connection cable remains securely plugged into both the remote and the amplifier.
7. Troubleshooting
If you experience issues with your XTBR14, consider the following:
- No Bass Control: Verify that the XTBR14 is correctly connected to the amplifier's 'REMOTE LEVEL PORT'. Ensure the amplifier itself is powered on and functioning correctly. Confirm that your amplifier model is listed as compatible.
- Intermittent Control: Check the RJ45 cable connections at both ends for looseness or damage. Replace the cable if necessary.
- Damage: If the unit appears physically damaged, it may need replacement.
If problems persist after checking these points, consult a professional car audio technician.
