Trying to decide which of the mainstream brands (Pioneer,JVC,Kenwood,Sony, etc..) has the most decent sounding drivers for my son's car. He's a centennial and like much of his peers, doesn't really know the meaning of clear sounding music. Just using the head unit power from a Pioneer DMH-241EX. It's going in a 2009 Subaru Impreza. Thanks for any help.
