some cars have it some donā??t, if it says premium sound or some thing like that on the front speaker grills then you probably have a factory amp also if you open your glove box you will see the amp behind the glove box, to see it may require pushing in the sides of the glove box and folding it all the way down and if you have a tape player or just a radio then more than likely you donā??t have a factory amp oh yea the premium sound package isnā??t that premium.
