About a 2 week ago maybe my car wouldn't start I believed my mom may have connected the cables wrong when she was helping me since the first attempt didn't do anything I managed to jump start the car fine when I connected the cables during the 2nd attempt however while the car now works fine my radio (aftermarket sony) won't turn on I've checked the 15 A fuses under the hood and under the steering wheel as well as the 10a fuse underneath and the not blown I tried removing the radios face and re-installing thinking maybe the conducters weren't touching and still no go everything else works fine lights in/out of the car power locks/windows everything electrical except the radio anyone know if there's another fuse to check or what could of happend I have no clue how old the radio is it came with the car when I bought it any help would be appreciated

 

Try checking the deck for a small tubular fuse.

 

Also try using punctuation.
