I HAVE A STANDARD 2.4 S60, NO TURBO AND RECENTLY REALIZED THAT MY CENTER SPEAKER DOES NOT PUT OUT SOUND. IS THERE A WAY TO ACTIVATE THE SPEAKER, OR TAKE IT TO THE DEALER TO INSTALL A SPEAKER.? MY CAR HAS A HU-613 STEREO MODEL IF THAT HELPS.

Remove the cover and see if there is a speaker.Most of them don't have a speaker there.
