I just installed the pioneer dxt-2266ub package in my truck and when i tried to adjust the audio. like the bass and treble and what not when i push the volume button and it says audio all it will let me do is the fade and balance. just trying to figure out how to adjust the bass and treble.

Find the audio settings....turn off loudness. Look up manual. I run my stereo with bass on -1 mids on 2 and treble on 4.

This is the right diagram for a 98 ford contour. If the color does'nt match, can you post the last 8 digits of the car's VIN?

See the connection diagram on page 11 of this manual.

Do the instructions on page 9 of this manual work?

Go to your audio settings and you should see bass and treble adjustments or google your make and model of stereo and look at the manual online...

Hope this info helps
please let me know if you need any further info

did you make sure the face was put back on correctly?

You can only use bass and treble if your Z-Enhancer is OFF. If it is on excite or bass boost you cannot adjust bass or treble

in newer sound systems they usually have an button that says audio with push of the button it should give you options of adjusting balance fade bass treble etc.
