I looking for a good car audio player and speakers.. I don't want to go with rockford or Infinity as they're a bit too expensive and I'd like to settle for a good Japanese brand. for players, Pioneer, Kenwood, Sony, Clarion, JVC.. Speakers - JVC, pioneer, sony, alpine.. what is the good combination and how about their sound quality and durability?? What is the best frequency range for deep but clear sounds? Pls help....
