I have a aftermarket stereo sony cdx330 and one day it turned off and i turned it back on and it did it again untill it does not turn on at all. i checked all the fuses and all of them are fine, but where one fuse goes labeled "panel" it seems like it is not receiving any power(i checked it with a fuse tester). what can it be? relay? wiring? HELP i want to listen to my stereo and sub again im going crazy withought my music!
