DDX 7015 kenwood

Is there any way I can install the 7015 and still use the sub woofer .Getting low on funds. I am trying to keep the tweeters in the dash and door speakers and use the sub for now or do i still have to get a seperate amp for the sub

I doubt if you wish to use the Nissan amp with the new HU, I certainly wouldn't. Without the Nissan amp you will need an amp for any subwoofer you might use. The existing one is not much of a subwoofer, only six inches diameter.
If money is tight, you might consider replacing the rear door speakers with 6x9s. They will give you much more bass than the stock subwoofer and be less costly than a subwoofer with amp. You will also find that the stock rear door speakers will be overloaded rather quickly using the new HU. Obviously, this is not the best solution if you desire a large thump - but it is better than nothing.
