I am having the radio works but no audio issue.

Bose system, aftermarket radio (worked for 6 years), no blown fuses, connections are solid. All speakers have no sounds, but I still have the beeps from using the steering wheel buttons. The beep will stop being audible if I pull the fuse for the amp. Is this a head unit issue? I'm in the middle of a cross country trip so don't have access to tools or anything right this moment. Looking to save my trip from days of silence.
