How to Enable the Equalizer on a Bose System in a GM Truck
- 1). Turn on the vehicle and the stereo. Consult the vehicle's manual for a description of the EQ settings and what to expect when the individual settings are engaged.
- 2). Press the "EQ" button on the radio's faceplate. Rotate the "P-Select" knob to cycle through the individual modes. Stop when a satisfactory setting is discovered.
- 3). Adjust the system's volume to determine how the individual settings perform at different levels. This can matter, since enhancing bass and treble at high volumes can result in unwanted distortion.
- 4). Customize the settings (if so desired) by entering the "custom" mode. This allows custom tailoring of bass, midrange and treble according to individual preference.
