this morning i pulled out of my driveway and i started on my way to work, when all of a sudden my headunit shut off. it turned completely off, it even made this little beep that reminds you to take the face off when you turn the car off. and then i noticed that not only did my headunit turn off, but im not getting any power going to my amp. i checked all the connections and wires, and they're all fine. does anyone know what could be the problem. the amp is new, i just got it in april or may, and the headunit is maybe a year old.
