I'm making an ambulance into a sweet ride with great sound. only problem, there's no factory speakers or anything. I need as much help as possible with this project. I'll have four speakers in one box, one 2k amp and one dual 12" sub. I I'll also have a double din stereo in the box of the ambulance with no wire harness. if somebody knows all of the parts and wires I would need that would be amazing! this probably doesn't make sense so let me know if you need clarification!
