Alpine MRV-F400 - Wiring Details and Diagrams; Ground Lead Connection

© Ground Lead (Black)
Connect this lead securely to a clean, bare metal spot on the vehicle's chassis.
Verify this point to be a true ground by checking for continuity between that point
and the negative (—) terminal of the vehicle's battery. Ground all your audio
components to the same point on the chassis to prevent ground loops.
