Yes, you need to connect the blue/white wire for the PAC C2R-CHY4 amplifier. It is the remote amp turn-on wire and must be connected to the remote power wire from your head unit, whether or not you have a factory amplifier.

The likely reason for no sound when installing an Alpine stereo in a 2008 Jeep Wrangler with a PAC C2R-CHY4 is that the original head unit uses the CANBUS to control the factory amplifier, including fade functions. Without proper communication or an added power wire to turn on the amp, the amplifier may not activate, resulting in no or very low audio output, especially from the rear speakers.

If your vehicle is a compatible Dodge, Chrysler, or Jeep model and has a factory amplifier or requires navigation outputs, then the PAC C2R-CHY4 is needed to install an aftermarket radio like the Alpine UTE-73BT. It retains the factory amplifier (if equipped) and provides necessary outputs for the installation. Check vehicle compatibility to confirm.
