Speakers!
 

I recently purchased a 1984 Mercedes Benz 190e. The radio sounds like I am listening to a tin can. I am not sure if it just because that is how the radios used to sound or if it is a speaker issue. I was planning on replacing all of the speakers inside to give the audio more bass and a better overall sound. What would you recommend? I think they are all 6 in speakers at least the two in the back I believe are. Any help or suggestions are much appreciated!

I'm not sure if you can buy Bose speakers for cars but if you can I would go with Bose.
