I needed what I thought was an alarm speaker for a project so I dug up my old rear-hatch speaker. You know, the one that makes that terrible screeching noise in the S. Apparently, it's just a speaker, not a piezzo beeping speaker like I originally thought. Which begs the obvious question, why not change the shutting tone to something sexy buttery smooth like the X if all it is, is a sound file like the passenger door tones?
