The Infinity Gold Amp is a proprietary amp that could be installed in your Chrysler or Jeep vehicle. It was popular in Jeep Grand Cherokees in the mid-90's. An amplifier is the portion of your vehicle's audio system that provides extra power to your speakers, leading to an overall more powerful sound. Amp replacement is generally only necessary if the original amp has failed. You'll know the amp has failed as it will produce speaker distortion or no sound at all, depending on what is wrong with it.
