I have the 03 LS Premium Sport with the upgraded sound with the 12 (ish) speakers without the navigation. Has anyone tried to upgrade the small speakers by your inside knee on the tranny hump? I picked up a set of the 3.5" inifinty speakers and was getting ready to install them when I realized that the ones in the factory location are only about 2 inches. I didn't really get into it too much as I was short of time but am looking for suggestions. Thanks
