Once all connections are secure, reconnect the vehicle's negative battery terminal. Turn on your head unit. The KB-10XP should power on automatically via the remote turn-on wire, indicated by its power LED.
Adjusting Controls
- Bass Level (Remote Knob): Use the remote level control knob to adjust the overall bass enhancement level. Turn clockwise to increase bass, counter-clockwise to decrease.
- Sweep Control: This knob allows you to select the center frequency of the bass enhancement. Adjust it to target the specific low frequencies you wish to boost.
- Wide Control: This knob controls the Q factor or bandwidth of the bass enhancement. A higher setting will affect a wider range of frequencies around the sweep point, while a lower setting will provide a more focused boost.
