W202 C230 Speakers

[outcast569]

Hey folks, recently got a 98 C230. Looking at changing the speakers out. What I cant seem to find right now is what to replace them with. Right now Im stuck at the rear door speakers. Every one I speak to pretty much is giving me 4 speakers 2 front and 2 rear deck. No one seems to be speaking about the rear door ones.

I need to figure out if this is good enough or I should be replacing the rear door ones as well. Pretty much just lost at this point.

All I know is its a non bose system at this point.

Thanks for the help folks.
