I was reading a review on an adapter on crutchfield and thought this was interesting an interesting piece of information for all future maxima bose replacement wannabe's :
If you are buying a car receiver on Crutchfield it probably has pre-amp outputs - use those instead of running the speaker outputs into this adapter and essentially just using an external device to create additional pre-amp outputs. For me, my new receiver sounded okay with this adapter but not quite as good as I expected. So I tried running the pre-amp outputs from my head unit to the "speaker" leads (really the inputs to the factory amp) and it worked perfectly. There is no level balancing required of course, and it sounds better now too - voices are a noticeably more realistic and the stereo separation/combination sounds better. So this adapter works well if you need it, but if you don't mind tinkering a little I would recommend considering not using it. I used an inexpensive "twisted pair" interconnect cable that I cut apart to get RCA connectors that I could wire into the leads to the factory amp.
My question is how would I wire the RCA connectors into the factory amp leads attached to each speaker???

Use the ground shields of the rca outs for (-) on the car's harness at the deck. The negatives (striped wires) on the nissan adapter harness will go to the rca ground shields and the positive wires will go to the positive (center) leads of the rca's on the deck, for each channel. Four grounds, four positives.
