Sony CXS-GT4016F 6.5" Subwoofer

[Terminatez]

I don't know anything about Car Audio and I'm looking for some help in setting my audio up in my car.

I've purchased a Sony CXS-GT4016F which comes with 2 speakers in which I've had them installed in the front of my car. (Nissan Sentra 1997).

The sentra has 2 speakers in the back that are now messed up and sounds very vibratory, not sure why. I want to replace them with some speakers or sub woofers but I don't know which ones I should buy or how to wire them up. I'm not looking to put big woofers in the trunk. The current size of the holes in the back are 6.5" and I want to replace them with some speakers that produce decent bass, or some 6.5" woofers if possible.
