Hi guys. Doesn't matter on Chryslers if it has an amp. The wiring for the radio is the same. Unlike GMs and Fords, all Chrysler radios put out speaker-level output and will run speakers directly. When a remote amp or little amps are bolted to the speakers, they are just for tone conditioning for the shape of the vehicle. They don't increase volume or power.
Here's a diagram of the plugs. Note that there is no ground wire. A separate ground strap is bolted to the rear of the case or a black wire is clipped to the case. A common mistake is to use an ohm meter to find what appears to be the ground wire. It is really the dash light wire; it reads low resistance because of all the bulbs in the dash. When using that for the ground, the radio might work, and it will be grounded (poorly) through the antenna cable, but the dash light or tail light fuse will blow when the head lights are turned on.
Accessory (switched 12v)
Illumination (dash lights)
Mute (keyway) (usually not used)
RR - (keyway)
Antenna (turns on power antenna and / or remote amp(s)
