There are a couple of different varieties that we use on motorcycles.
One is a basic mic/earpiece setup that is connected to another via a small box. Limited range.
The other is a blue tooth setup. Again a mic/earpiece setup, connected to a small box which usually attaches to a helmet. This transmits to another unit wirelessly. Some of these have a range up to two kms. It should be possible to adapt these to fit in a car. EG. instead of an earpiece, change it to a larger speaker.
Some of these bluetooth units can also be used with mp3 players, mobile phones, some gps unites, etc.
Look up intercom bluetooth on ebay. There are a few there.
