does the factory radio in my ’03 Aztek have RCA outputs?
Jason, most late model vehicles do not have rca outputs on the factory radio. You would have to install a line out converter. Here is the Line-Out Converter you need:

If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck.
after installing my after market radio, I noticed the only way to have it come on was to connect the ignition and constant 12v wires from the radio to the constant 12v wire to the car. How should I wire it so that the radio goes off and on with the car? Currently the radio can stay on when the car is completely off.
Tiara, run a wire to your steering column and tap the orange wire in the ignition switch harness for a switched power source. Hope this helps. Good luck with your 2003 Pontiac Aztek stereo installation.
