Intercom systems have been used for years in airplanes, where pilots and copilots need to speak over the roar of the engines to safely take off and land. Not long ago they were adopted by race-truck and dune-buggy drivers with roaring engines, but what about putting a set in your Jeep or loud trail rig? What if you could speak normally to everyone in the vehicle at the same time? We installed a set of Rugged Race radios in the Cummins diesel-powered UAJK Jeep we built and found them great for conversing with passengers while bombing across the desert at high speeds. The system can be wired to also work as a hands-free cell-phone system or broadcasting VHF or UHF to other similarly equipped vehicles. The headset and intercom system can be used on CB radio frequencies with a custom adapter. Additional handheld radios can be added to the system in case you want to have an out-of-vehicle spotter who can calmly guide you over an obstacle rather than screaming over engine noise. Of course it's probably a bad idea, and likely illegal, to wear a fully enclosed headset while on the street since you still need to be able to hear emergency vehicles, but once you hit the dirt, the intercom can help you converse with family and friends without all the yelling.
