gmJake Posted July 21, 2011 Report Share Posted July 21, 2011 There is a small 1 inch round grill in the headliner above the drivers seat and one on each front pillar. What are these for? Quote Link to comment Share on other sites More sharing options...
jddmj Posted July 21, 2011 Report Share Posted July 21, 2011 The grills in the pillars are tweeters. The one about your head is for onstar, ete Quote Link to comment Share on other sites More sharing options...
JF-03-SS Posted July 21, 2011 Report Share Posted July 21, 2011 (edited) The grills in the pillars are tweeters. The one above your head is for the climate control Fixed your quote James. The onstar speaker is on the side of the overhead console. Edited July 21, 2011 by JF-03-SS (see edit history) Quote Link to comment Share on other sites More sharing options...
gmJake Posted July 21, 2011 Author Report Share Posted July 21, 2011 Kinda small for tweeters. Think they would have just been incorporated into the door speakers. Learn sumpin new everyday about this. Quote Link to comment Share on other sites More sharing options...
gmJake Posted July 21, 2011 Author Report Share Posted July 21, 2011 I don't see anything on the side of the overhead consule. I don't subscribe to Onstar anyway. Quote Link to comment Share on other sites More sharing options...
