I have a 2003 ION3. The supplied stereo radio/cassette/CD does not play MP3s, and the freqeuncy response is tinny. Turning the bass response up only distorts the bass.
Has anyone replaced the GM stereo with an aftermarket stereo?
What I want to do is replace the built in radio/cassette/CD with an aftermarket brand that plays MP3s in the CD player.
As far as I know there are no radio/cassette/CD/MP3 sets to buy, only radio/CD/MP3.
Once this is done I want to improve the bass response for the radio (and cassette). If this does not improve with a change to the stereo system then I would then replace the speakers. Anyone done this on an ION yet?
If anyone has done one or both of these things, what brands did you use and did it improve the sound without resorting to buying an additional amplifier?
