All i had to do was by the in dash kit and wiring harness and it should plug right in
who says you can't? I replaced the stereo myself on my 93 ford explorer with an aftermarket stereo with no problem.
Yes, an aftermarket stereo radio can replace a Bose radio in a 1997 Nissan Maxima. Remove the old radio from the dash and put in the new one. A new mounting frame might be required to make the new radio fit properly.
Yes, there is a free stereo wiring diagram for this car. It is in its maintenance manual, or a person could ask for a print out at an auto part store.
I have a Grand Marquis GS,it had no Amp installed.I bought a new JVC stereo that was on display for next to nothing,allthough it took some time,and i had to but a new harness to fit the stereo.But if you don`t have the time or know how i would but a stereo and if you have a Best Buy near you have them install it for you for around $50.00 plus the harness at $20.00.Good Luck. I just went through the same thing the factory amp input signal operates at a lower level than normal radios so if you bypass the amp you could destroy the factory speakers, so you have a decison to replace all the speakers with the special wiring harness, or buy the PAC-2 from cruchfield.com. in which lowers the the signal of the aftermarket radio to work with the factory amp & speakers. Please note it is still going sound the same because you will be still using the factory set up. I just did it to my 1987 mercury grand marquis and it works fine.
There is no way possible to remove the stereo and replace it with an aftermarket stereo. I have talked to 15 Nissan Dealers and Nissan head technical office. They all state that it can not be done. --+Skifo How Much

We have put an aftermarket car stereo in a car with the controls on the steering wheel. You have to check to see if an aftermarket wiring harness is available for that year and model.
I put an aftermarket system in my intrigue, and don't recall a "stereo accessory wire". Do you mean the power antenna wire? Or is this a wire on your aftermarket box? Here's a GM diagram: http://www.installdr.com/Harnesses/GM-Wiring.pdf
