I went in today to a car audio business, i had the exact same problem when i installed my custom deck. What i learned was that all 2000+ GM motor vehicles need is an Interface installed also, this is because the radio sends security signals that activate chimes in the car and a custom deck screws it all up, so you NEED an interface if you want your deck to work.
I had the same issue and spent a couple hours Googling answers and finally found that there is a factory amp in the car. The amp uses the Dark Green wire as a trigger. Once I connected the wire that feeds amp to the system remote wire from the stereo everything worked. Here is the Grand Am Wiring Diagram as I installed it. Radio Constant 12v+: Orange No Switched 12v Power. Radio Ground: Black/White Stereo Amp Trigger: Dark Green Front Speakers Size: 4x6 Left Front Speaker (+): Tan Left Front Speaker (-): Gray Right Front Speaker (+): Light Green Right Front Speaker (-): Dark Green Rear Speakers Size: 6x9 Left Rear Speaker (+): Brown Left Rear Speaker (-): Yellow Right Rear Speaker (+): Dark Blue Right Rear Speaker (-): Light Blue Hope this helps.
