    how do i run power to the fuse box to make the radio switched

  • Reply ModifiedLife May 12, 2008 at 1:20 am

    Billy, run a primary wire from the back of your radio to the orange wire at the ignition switch harness for your switched 12v wire. Hope this helps.

    I bought two rear sony xplod speakers and I’m trying to install them in my sunfire but every way we hook up the black and red cables makes my speakers fussy almost like they’re blown… can some one help me out please?

    I have a 2000 pontiac sunfire. My stock am/fm/cd display is out and volume is stuck on one level. Can I unplug this radio and replace with a after market or will this cause other things to not work. Some one said the air bags are wired through the radio?? Or if I unhook it, the car wont start. I can’t get an answer from the dealer.
    Thank you very much for your help!

    Just bought a 2000 Sunfire for my 16 year old son…..the rear speaker wires are not connected…not really sure what happened just want to know how they are suppose to be reconnected?

  • Reply ModifiedLife June 1, 2009 at 11:52 pm

    Beth, its hard to say why they are not connected or why they don’t work. It could be that the radio is faulty, the speakers are faulty or the previous owner had disconnected them. Our advice would be to take your car to an experienced mobile audio installer and have them troubleshoot your problem. Hope this helps. Good luck.

    my battery died and my car radio has theftlock and it wont play, do you kno the code for it its a pontiac sunfire 2000.

    thank you

  • Reply ModifiedLife July 29, 2009 at 2:16 am

    CJ, radio security codes are usually written in your 2000 Pontiac Sunfire manual or given to you when you purchase the vehicle. If you do not have the radio security code, you would have to obtain it from the local Pontiac dealer. Hope this helps. Good luck.

    i wanna know if you dont buy the correct harness for the sunfire radio will it cause the airbags not to work?

    i have hooked my radio up according to the 2000 Pontiac sunfire wire diagram and i get power but nothing on screen comes on… i can press eject and the motor for eject runs but still no speaker or lcd screen power… why is this? and i know the head unit is not blown because i hooked up in friends car to test and runs perfect

  • Reply ModifiedLife March 16, 2010 at 7:08 pm

    Chris, it sounds like you haven’t hooked up your car radio accessory switched 12v+ wire. Run a wire to the steering column and use the orange wire in the ignition switch harness. This will provide you with a switched power source. Hope this helps. Good luck with your 2000 Pontiac Sunfire radio installation.

    i recently installed a CD player in a 2000 sunfire and it doesn’t store memory…any suggestions?

  • Reply ModifiedLife May 18, 2010 at 1:35 am

    Jen, you may have mixed up the battery constant and accessory switched wires. The battery constant always sends power to the radio to save your radio stations and other audio settings. The accessory switched wire sends power to your radio only when the key is in the ignition and your 2000 Pontiac Sunfire is on. Check your wiring and make sure the correct radio wires are hooked up to the correct wires on your factory harness. Hope this helps. Good luck with your radio installation.

    I see 2 other people requested answers about hooking up an aftermarket radio in their 2000 Pontiac Sunfires. Will it cause problems with the air bag system?? Do i need to purchase an interface moduel???? What will i need to do to hook up a radio in my 2000 pontiac sunfire correctly??

    i am trying to get switched power from the fuse box and i looked at my ignition wires that run to the ignition switch and i have a yellow black and white. but no orange is the yellow wire the one i want

  • Reply ModifiedLife August 11, 2010 at 1:51 pm

    Bob, check searching for the orange wire. That is your accessory switched wire. The yellow wire is your starter wire. Do not use that wire. Hope this helps. Good luck with your 2000 Pontiac Sunfire stereo installation.

    Hello, I am not sure if my question will get answered, but I am stuck and desperately searching for a solution. I install audio systems and aftermarket stereos for whomever needs it without wanting to pay $300-$400 at a shop. My girlfriend’s car is a 2000 Pontiac Sunfire, and I had installed a 3200 watt systems to the factory radio. Upon realizing how terrible the radio was, (frequency separation), I went and got her an aftermarket head unit. After buying an adapter kit, I realized that (adapter said it supported 2000+ Sunfires) it wouldn’t fit. It was too wide and not tall enough. It also came to my attention that even without the adapter, the stereo sat out 1/2 to an inch too far out of the dash. So, I am wondering, what the hell am I supposed to do at this point? Everything looks factory, the wiring harness doesn’t have any signs of cutting, stripping, etc. and the factory radio was one with the TheftLock feature. It’s looking as if someone put in a different dash, but that seems entirely unethical. Also, what’s keeping the radio from fitting is a large plastic something. I am unsure as to what it is or how to describe it. Thank you.

  • Reply Luke April 30, 2011 at 10:36 pm


    After taking a closer look, I realized that once installing the adapter and replacing the panel, it fit, with the exception of having to use a plastic spacer. Thank you.

    I’m looking for a schematic wiring diagram for the rear speakers in a 1999 Pontiac Sunfire, I know the color codes but for some reason I have no sound getting back to the rear speakers. I need to trace the wires to see if they are disconnected somewhere. The rear left & right speakers are now hardwired to the Explod everything else is going through an adapter harness. Sony Explod deck works as do the front left & right speakers. To the best of my knowledge, Haynes manuals do not provide detailed speaker wiring schematics. Just wondering if there might be a junction box somewhere as it is odd that both rear speakers are not receiving power/sound. Thank you in advance to all contributors.

    How do you install a Pioneer DXT-2369UB into a 2000 Pontiac Sunfire? Where does the black cord with the little metal piece that looks like a “U” go? anyone?

  • Reply Casey February 25, 2013 at 10:49 pm

    I have a 2000 Pontiac Sunfire and I’m needing to replace the stereo. There is a red light that blinks and is labeled security system on the front of the current stereo(which is the one that came in it from the factory). My dad says that if we try to change the radio out that the security system will shut my whole car down. No one else seems to know that I’ve asked. Can anyone help me, please? Thanks!
