Radio Presets

[jat454]

Is there anyway to adjust the Auto Tone presets in a 2003 Impala LS? I am impressed witht the bass but I find that the bass and midrange are a little too powerful. I'd like to just tweak the Jazz and Country settings a little.
Thanks.

As far as I know no way to tweak the factory settings, just set the individule tones to your liking.

It seems though that the Auto Tones adjust more than bass and treble, also some midrange frequencies. Manual setting is only for bass and treble.
