Wondered about this one over the weekend. Since I try to troll the local Pic-a-part when I can, are there any factory sound system parts (speakers, stereos etc.) worth watching for? I am not an audiophile and am not current on the "latest and greatest" tech, but it would be nice to play a CD or plug in a thumb drive or Ipod and have some tunes. To make things worse, I won't cut my dash so I would have to mount the unit somewhere else (I guess). Any tips would be appreciated.
