[pnoywitmustrdsau...]

so i was driving on sunday and i was listening to the radio. sub amp and everything, no problems with it. i left the car to eat something and when i came back and drove back home i notice that my radio was off. i tried turning it on it wouldn't then i notice the clock wasnt on either. so im thinking its the fuse i checked under the hood, nothing wrong, i didnt check the fuse by the kicker panel yet. but do you think its the fuses? tell me what ya'll think!!!
