Summary: Got them for the shallow mounting depth. Put in the back of my 82 240d Mercedes. Sound pretty good with 4" speakers up front. Running them with a Clarion head unit. Don't expect too much bass. Some decent mid and great high sounds. Good value for the money. I had a similar blaupunkt, the 5 1/2 sister speakers (another car) with the foam insert in speaker hole from Crutchfield and the were GREAT!
