As Bob Baker has already pointed out, you
cannot make this change unless you also change the power amp (the one that is
mounted where the center dash speaker would be mounted in a lesser car. The
correct power amp is clearly marked as being for a “Quartz Lock”
radio only. Once done, this produces a superb sounding radio, with all
the modern convenience of digital tuning etc. The 82/83 radios have this
feature from the factory, the 81s do not. The heating and smoke are telling you that
you are about to totally destroy your radio – turn it off and leave it
off until you get the right power amp! Dick Benjamin From:

Behalf Of RWestra@xxxxxxx I am trying to replace an original
equipment analog dial radio in my 81 Imperial with a digital dial Chrysler
radio of perhaps a little later vintage. The radio I am trying to install is an
AM/FM/Cassette with the six small pushbuttons to the left of the readout.
It has the gray and black. 7 wire, 4 speaker system connectors on the
back. I have carefully connected the wires as correctly as I can.
The four positive speaker wires were connected to the appropriate
speaker plug going to the rear amp. The negative speaker wires were
joined together and connected to the black wire on the rear amp plug. Now the problem. When I connected
the radio to the '81 I got a pulsing intermittent radio sound from the
speakers. I cut the black wire to the plug and the radio worked.
However, it runs very hot. After about 15 minutes of operation I
saw smoke coming from the power transistor area. You can see the
digital readout dim slightly when heavy base tones are played. The radio
sounds great but I suspect life will be short. Maybe an hour or so. My suspicion is that with the black
ground wire disconnected the power transistors are running out of control and
overheating. By connecting a 10 ohm power resistor in the
break in the black ground wire the base tones are subdued but the radio still
runs hot. By now you electronic types will
recognize that I have no idea what I am talking about. But I do need
help. Has anyone made the conversion from the
analog dial radio to a two plug, four speaker, digital dial,
successfully. If so what do you suggest. I am tired of pulling the
analog dial radio every six month for the bi-annual volume control bath.
Also the tape player has started to eject while playing. Thanks for your help. Rolland
