sounds like they wired your N2 straight into the harness for the audio of the car which is the wrong thing to do. most vehicles that have a "brand name" (ie the Bose system in your altima, or in a Z) have external amps, usually under the front seats or somewhere remote from the head unit (usually a cd changer). whenever you hook in the aftermarket stereo, it's amplified internally and that signal goes to your amps and screws with them. this can be avoided two ways, either bypassing those amps all together and taking them out, or running the sound to the factory amps out of the RCA outputs that are supposed to go to aftermarket amps since that signal is unamplified
