Jerry,

If is's like my car you already have an amp. 05XJR with Alpine System.

 

Jerry, no, those speakers will be fine in your car as is. So, buy the speakers and wire them up. Just make sure to get the polarity of the speakers correct or you will have a decreased amount of sound from the system. If in doubt, let me know.
