I have a Touring with stock stereo. I was wondering if anyone knows "if" they have tweeters in the dash, or does it just have the four speakers in the doors. I dont seem to really hear anything from the front dash. If thats the case are they pre wired so I could add a couple in there??? Any recommendations?? I saw elsewhere on this site the cx 5 posts and how the plastic grills are removed, is the 6 the same? Diddnt want to marr the dash up. THanks.
