2006 Five Hundred Sound system question
 

I have 2006 Five Hundred, came with the base CD player, so i went to the wrecker and pulled a 6 disk MP3 unit out, Works good, Noticed better sound to, so i figured ill replace the speakers, bought 4 6x8's pioneers and followed the colour wiring on another site. Sounded like crap!!!

How do paper speakers sound better then rubber plastic pioneers?

Am i better off pulling the speakers out of the same car i got the Stereo out of? even though it came out of a 2008 Ford Taurus ( same car ) at that time lol. ?????
