QUESTION: with all due respect{i'm certified ase,chrysler master,cummins master,34 years exp}where did you get your info?i been searching everywhere for that info,radio has never been installed,but no tags to identify.i asked one of the other experts there he said 4ohms??thanks HD

Answer
i been installing car audio for 25 years, that is what i remove from  the old pck ups, some have a single oval speaker in the midle and some other have 2 speakers  in the dash  

there are 10 ohms for older trucks and cadillacs, some 8 ohms, there was no 4 ohms speakers back them
there was some 1.5 ohms in premium sound like the corvettes and el dorado easy to recognize yellow coil next to it
not your case, i also know the outputs transistor in your radio, that is why i recommned to use nothing under 8 ohs


just do a search on delco 10 ohms speakers
