A car audio installer is an automotive installation technician. Their duties involve installing a sound system in a vehicle, although they may also repair a faulty speaker or diagnose audio issues. These technicians are often familiar with the wiring of other automotive electronics, such as backup cameras, Bluetooth, navigation equipment, and car alarms. Installation of automotive electronics usually requires the removal of various interior parts, and someone in this job may be required to build enclosures for additional sound equipment, like a large speaker or stereo. A car audio installer may also be expected to provide customer service to potential customers over the phone or in a shop.
