SOURCE: Cannot Set the Treble & Bass
Bass and Treble controls allow you to adjust each setting from
-7 to +7 once you have calibrated your vehicle's interior sound with the optional Alpine IMPRINT software.
Is this what might be causing your setup not to work?

Here is a manual for the radio. If you go to page 14 it will tell you how to set the EQ.

SOURCE: how to adjust treble and bass
At the lower left of the unit, just right of the power button is a button marked LD, with A-M below that. Push this button and the display will say BATT, then, in a couple seconds it will display 2 numbers. The left number is the bass and can be adjusted with the select arrows (left & right arrows). The right number is the treble and can be adjusted with the volume arrows (up & down arrows). If you push the LD button once more, it will display BAL, then 2 numbers. The left is the left-right balance & the right is the front-back balance. They can be adjusted in the same way with the arrow keys. Hope this helps someone.
