The air conditioning uses up the battery power.
a ballast resistor drops voltage. In chrysler products it drops to six (6) volts.
1st option is that the air conditioner has ceased and is dead. There is no 2nd option.
you need to tighten your fan belt as it is moving and now slipping on the A/C pulley that you just turned on.
belt slips a little when comp comes on -relace belt
start by checking a/c compressor.
There are usually vents under the tail lights.
Your air conditioner compressor may be seized up. If it is seized up the belt would lock up every time you turn on the air conditioner, causing the car to die.
A common choice is an electrolytic capacitor with a high enough voltage and capacitance rating to stabilize the voltage. To wire it, connect the positive lead of the capacitor to the positive terminal of the car battery, and the negative lead to a good ground point on the vehicle's chassis. Be sure to add an appropriate fuse in line with the positive lead for safety.
If it's a creaking noise then it is most likely that your compressor is broken.
Possibly the accessory belt needs tightening or replacing -or- the bearing for the drive pulley may be going bad.

The rem (remote) wire on a car amplifier typically carries a voltage of around 12 volts. This wire is used to turn the amplifier on and off, sending a signal from the head unit (stereo) to activate the amp when the car is turned on. When the ignition is in the "on" or "accessory" position, the rem wire should receive a voltage close to the battery voltage, usually around 12-14 volts.
