The negative lead needs to go directly to the battery, either at the
battery terminal, or (as recommended by Chrysler) at the point where
the negative battery cable attaches to ground.

You haven't said where the radio is mounted. It sounds like it might
be installed in the rear with a remote head up front. In any event,
the radio chassis ground needs to find the most direct route to the
chassis. If you are using a remote head, you may need to use some
ferrites on the lead between the head and the radio.

Ignition (spark plug noise) is a staccato, popping noise. Alternator
noise is a high-pitched whine. Both change with engine rpm.

Put those resistor plugs back in. There is a good reason for the
factory to use them in the first place.

use the ground on the left kick panel can't miss it there is a bunch of
wires going to it
