Well that sucked about your car, I thought the rears were 5.25 so I'm glad I asked. Now are you running an amp or just what the head unit provides. I'm not much up on stereo systems for cars and just want something a little nicer than the old junk speaker that I have in back. I got the Sony speakers that someone here recommended for the fronts so now I might as well replace the rears too. At least I know what to look for now.. Thanks for taking the time out to reply, I really appreciate it ..
