Replacing the Station Push Buttons/Radio

Ok, just got off the phone with Gordon the dad...he said to send his son Greg an email, as Greg handles all the Mopars. A little side note I inquired about changing dads from am/fm Mono to am/fm stereo...kinda pricey $459!! So I said well I will just share/split the speaker wires and he said "dont do that"!! Apparently you dbl the amperage if you do that and will fry ****!! So looks like I wont be doing that either...
Ok sending Greg an email...will update when I can

You can do this by using two speakers and some resistors. The ohm rating (impedance) being the same in the end is what you are after. I did this all the time in my younger years and never damaged a radio.

Here is a Speaker Impedance calculator for you to look at.
