I would think for best sounds you would forget the dash speakers and put a couple of 6 1/2" speaker in the kickpanels. The quality of the speakers that you can get into the dash w/o cutting are barely worth the trouble. I am going to buy a couple aftermarket kickpanel covers and install a pair of 6 1/2" Polks. Got 6x9's in the rear deck as well. Just a thought
