Anybody??

The louder I go the more it jumps, like everytime the bass hits the screen flickers. Could this be a bad ground?

Take a multimeter and set it to DC volts somewhere in the double digit range. And then put the positive on your positive battery terminal and negative on your negative battery terminal while your bass is hittin, it should't ever drop below ~12.4 when the car is off or ~13.4 when the car is on.
