Chrysler part # 77KICK10. They are 2-way direct-swap speakers for JKs. I have 4 of them and am happy. But you should look into an amp - not sure how much power that 750 puts out but I'm sure it is anemic at best. You can only get so far with a speaker swap.
Have you heard them? A sub is a sub for the most part. I have a 10" Pioneer that works fine. Are you planning on using the factory enclosure? The enclosure is a rather important part. It's your cash, get what ya want.
