The 6x9 JBLs fit right onto the existing mounting holes from the stock speaker. If you ever decide to do the rear door speakers you'll need an adapter.
Because the magnet on the back the JBLs is much larger than the stock speakers' magnets, you'll have to cut away some of the plastic in the speaker hole. It's just thin plastic sheeting so a utility knife does the job.
On mine, I was only able to line up three of the four mounting holes on the new 6x9s for some reason, but it makes no difference in the security of the speaker to the door.
Other than that, you just cut the connector off, strip the ends of the wires, crimp on female disconnects (3/16" for positive and 1/8" for negative if I recall correctly) and connect them to the speaker.
As far as powering them, I just have the stock head unit. Unfortunately, I have the media screen w/ the back up camera etc so some sort of aftermarket stereo won't fit and to add an amp to the existing setup gets pretty expensive. I can't tell you how much I'd rather just have a double din opening to put a good unit into.
Feel free to shoot me any questions about the install etc, I've replaced all the speakers and had to work around some of the more inconvenient little hurdles Nissan likes to put in their cars.
