    Ok well I have the same probs with my tahoe and Im guessing it has something to do with the radio the pink wire we spliced into the aftermarket from the onstar system from what i read it only turns on when the car is fully cranked up I kinda like it if you think about it your actually saving ur altenator in ur car since it only cuts on when the truck is turned on as of now im not sure on how to fix that but it hasnt been a great inconvience…….

    if u need help with any other probs on ur gm truck hit me up and will do my best to help you out

    Let me go a head and clear this up once and for all!!!

    Heres the backgound of the problem: I installed a aftermarket indash in my 2004 tahoe all the lights and the screen came speakers played but went out after 10mins im a stereo guy so this freaked me out what I didnt know was that there is an internal amp built in to all SUVS that must be turned on so i searched for a way around after a couple of bogus forums and a few rude chevy tahoe forums I was about to throw in the towel with my install and pay someone to do it but being the stubborn person i am i decided to call my local audio shop for tips(i mean seriously why pay these guys 100bucks when im like reallly close to fixing this thing)

    Solution: If you have an aftermarket stereo or Indash dvd/TV and you have a tahoe/suburban/yukon from the years of 2000-2004 all you have to do is cut the pink wire loose from the Onstar harness loose(This wire power the internal amp in your truck and tells the speakers to turn on) and connect it to the orange wire on the factory stereo harness(12v power wire always stays on when your vehicle is on) and your aftermarket stereo/indash will work fine

    No bull No smoke and mirrors no technical jargon your gonna forget just follow these steps after wiring your aftermarket harness up to your aftermarket stereo/Indash and it will work fine dosent matter the name brand of the unit it will work and if someone tells you to rewire all the speakers from the amp kick them square in the nutz for being stupid. Im not a professional but I am technical and this will work

    I found out from a local stereo shop that the wire colors are consistant with On-Star equiped auto’s. The correct harness adapter is $150 if you want to keep the On-Star feature.

    Raoul, your 2003 Chevrolet Tahoe may have a factory amplifier that needs to be turned on by your after market radio. The car stereo amplifier trigger wire has to be wired up to turn on the factory amplifier in your 2003 Chevrolet Tahoe. Hope this helps. Good luck.
