W204 Speaker upgrade

[johnchallenger]

Can anyone help with my intention to upgrade the factory speakers . I will be running a Helix amp and a subwoofer but am considering replacing the speakers too.

Has anyone successfully located a pair of speakers that will sit BEHIND the existing speaker grills because I don't to modify the door panels.

I've approached several (quadruple that ha ha) car audio specialists but the four responses I've received so far have been laughable. None of them answered my questions/suggested a suitable speaker!

I have done this installation in my C220 and current C300, replacing the front speakers and tweeters with the Harmon Kardon items - the rear door speaker replacement is much more involved, so haven't done those but a very worthwhile upgrade IMHO, especially if you also intend to run a separate amp and subwoofer.

Took me about an hour.
