start off with just hooking the cd player up with the wiring harness that best buy can get you. you might also need a dash kit for the jeep to... The reason i am saying that is because most wiring harnesses these days are compatable to run the stock speakers with out any wiring off of the factory amp.. I had a buddy that i helped put a cd player in his gto and it was a factory amp car and he didnt have to make any adjustments with the amp wiring. and when you get the cd player hooked up see if your stock speakers still work correctly. if they do all you will need to do is run your rca wires and remote wire from your cd player and get you a power cable ran. if you hook it up and they dont work i dont know what to tell you I was just looking for the easiest way out..
