Kenwood KGC-4042A
A 7-band graphic equalizer designed for car audio systems
Overview
The Kenwood KGC-4042A is a car audio graphic equalizer for tuning frequency response in mobile sound systems. It has seven adjustable frequency bands and runs on the 12V supply typical of automotive installs. An attached wiring harness carries RCA cables and power/ground wires, so it hooks into an existing setup without much fuss. One tested unit was reported to have worked well after years of disuse. It came out of an extremely low-mileage vehicle, which says something about how well these hold up in a stable environment.
