I'm about to get a 1990 190E (its a hand me down). It still has the factory speakers, which are terrible. Anyone know the speaker size for the front and rear speakers? I think its 4" or 6 1/2", but not sure. I don't want to do any cutting, just want to pop the new ones in and go. Any held would be greatly appreciated. Thanks.

 

You can fit 4" speakers in the front dash without any cutting. You might need to cut the metal tabs tho. In my case, I didnt have too. Im not sure if you have door speakers too. But if you do, they are 4" too and are subwoofers. The rear speakers are 5 1/4".

 

yeh man 4.5 for the front and 6.5 for the rear. trust me i had to do it myself.
i have used mtx roadthunder 6.5 competition splits for the rear and 4.5inch fusion splits in the dash and it sounds awsome.
let me now how u went.

 

how did you mount the dash speakers?

They fit right in there if you bought 4" speakers. Some 4" speakers wont clear the speaker grills so you may need to cut off the mounting tabs.
