==Overview==
In the United States, two levels of audio systems were available with the 900 and 9-3. The standard level has four speakers and the upgraded level two system adds two speakers in the front doors for a total of six speakers.
==Headunit==
The head unit found in most models is manufactured by Clarion and is slightly less than double DIN height. The head unit is married to a car and will not function in another car unless it is first divorced and then remarried to the new car. The head unit may be a cassette and radio or single CD and radio unit.
