These C3 dash speakers have an overall depth of 2 1/4 inches. The outside diameter of the magnet is 3 inches. The mounting plate is 6 1/8 inches long x 4 1/16 inches wide.
These are for aftermarket radios NOT for factory original radios. For Original radios use part number 523102

Bei part #523102 steht unter anderem
This speaker is the same depth as the original speaker. It has been engineered to work with the Delco radios that require 10 Ohm speakers and will work fine with all other brands of car radios including radios of modern design and our Am/FM Stereo conversion radios

So, hast Du ein originales Radio? Passen dann die 4 Ohm dazu?
Aber die Zusammenhänge kenne ich eher nicht, da gibt es hier bestimmt andere Wissende, was wie zusammengehört und was evtl. passiert, wenn das nicht zusammenpasst...
