Three fuses and one relay are involved for the Bose Radio and CD Player (head unit). -Fuse #40 (7.5A) - located in the Fuse Box (driver side, below instrument panel), provides backup battery power (always ON) to the head unit.-Fuse #22 (15A) - located in the Fuse Box, provides power to the audio components (speaker amps) via the Audio Amp Relay.-Fuse #21 (10A) - located in the Fuse Box, provides power to the head unit when Ignition is in ACC/ON. When radio is turned ON, the head unit provides power to energize the Audio Amp Relay.-Audio Relay - located close to the Radio/CD player, provides power to the speaker amplifiers.
It’s possible that you have a loose connection behind the head unit (radio/cd player).
