Chevrolet: 2005 MAXX radio dead? Any advise to check what is going...

Nothing really happened, when I started car at the morning radio
didn''t powered on. Also back radio (for rear passengers) offline too
- no sight of life. Everything else works well (light, air, dashboard,
AUX powers, signals.....)

One thing: last night I accidentally triggered alarm by pulling badly
closed trunk door... may it cause radio to lock? die?

Fuse is fine, (if checked right one)... 10A fuse?
