i went to a junkyard today for new headlights, and well i left with some mach 460 parts. I have the head unit and the box for the trunk. I did get the door speakers or tweeters. I want to know how i would go about changing my stock setup to mach 460. I am driving a 2002 V6, and i believe the car i took it out of was a 2001 or 2002, i can't remember. I have the whole box, and all the nuts and bolts from the box. I just want to know if my car is already prepared for install.
