2004–2009 AP2 S2000 stereo wiring diagram

The AP2 version of the Honda S2000 underwent quite a few revisions. This facelift represented an excellent upgrade for the mid-cycle revision. Even though the S2000 was discontinued after 2009, there’s been rumors of a return.

Although there’s been plenty of changes from the AP1 to the AP2, one thing that didn’t change is the single DIN stereo. To remove your S2000 radio, make sure to follow our instructions above. Depending on the model or year of your S2000, you may have additional premium sound upgrades, including subwoofer.
