hi very familiar with the 89-94 maxima stereo's... not as much with the bose but i know them like the back of my hand... my mom has a 99gxe stock speakers and the only option besides power driver seat is the cd player... can anyone tell me the rms/watt that the factory deck puts out and how much power the stock speakers can handle and what size they are... and what size speakers are in a 99 with bose?
