I am inheriting a 1977 Mercedes 230 and I need to know the stock speaker size (I don't have the car yet so I can't see for myself. Can anyone tell me where I can find this info? I looked on the net but found nothing for that car.

Thanks.

 

^ Found it. 4 inch stock speakers in the front is NOT going to work. I guess I will have to chop some metal

 

...or build some pods, door enclosures, etc... and use the 4" holes for mids, and add a tweeter to the sail panels or A pillars.
