Interior problem
2007 Buick Lucerne 6 cyl Front Wheel Drive Automatic

I am not sure if this is even possible to fix, but the AUX input for hooking up an MP3 player on my Buick is not very loud. I have to crank the mp3 player up all the way, and adjust the volume at least 50% higher on the stereo in order to get a decent volume when using AUX input. When I switch back to the radio, I am practically blasted out of the car. I have a similar input on my Ford, and use the same player without having to adjust the volume like this, so I don't think it is weak input from the player. Is there a way to adjust the sensitivity of the AUX input so I don't have to jack up the volume when I use it?
