Hey guys I just bought an 03 touring 350z 3 days ago , and when I bought it He told me the radio didn't work. Its on but does not emit any sound, and the other day while driving my headlights , gauge lights , and a/c all turned off. What could the problem be

 

A/c amplifier (white box below the stereo) connection may be loose or need to be replaced.

 

The hesdunit could be a fuse same with the other issues if you're lucky. Check the fuses under the hood and kick panel.
