Yea I think I jumped to a conclusion...Co-Axial = two speakers in most adds the tweeter, there are also Tri & Quuad-Axial.. I never get more than Co-Axial .
As for speakers in the kick panel don't expect too much as the location is poor for base reproduction & the highs are lost in the carpet. You just want good enough quality to avoid distortion, at best the speakers will create fuller sound, you might consider fitting a couple of tweeters in the center dash location if you don't have the 3-speaker dash.
