Once installed, the BXM-100MX is ready for operation. Adjustments should be made carefully to achieve desired bass enhancement without distortion.
6.1 Initial Power-Up
Turn on your vehicle's audio system. The power LED on the BXM-100MX should illuminate, indicating the unit is active.
6.2 Adjusting Bass Enhancement
The BXM-100MX features two primary controls on the front panel, typically for frequency and width, and a remote level control for overall bass output.
- Frequency Control: This knob allows you to select the center frequency of the bass restoration. Experiment with different settings to find the optimal frequency for your music and speakers.

- Remote Bass Level Control: Use the wired remote control to adjust the overall output level of the bass restoration from your listening position. Start with a low setting and gradually increase until the desired bass impact is achieved.
