Default no sound from aftermarket stereo

I have a 2001 yukon xl with onstar that is not used. I bought a new aftermarket stereo and installed with provided harness adapter. Power comes on and everything seems to work on the HU, but there is no sound. I searched around the web for anyone that might have the same problem but came up with only a few similar questions. the understanding i have is that the factory amplifier will conflict with the preamp built into the aftermarket stereo. but how do you bypass the preamp? The remote antenne is hooked up to the remote wire on the harness, but nothin'. Now there is the main harness input on the factory radio, and there is another 10 or so pin harness that also attatches to the back of the factory radio. There is nowhere for this other 10 pin connector to go on the aftermarket unit or harness adaptor. Is this related ? Someone PLEASE help!!!

Do you have the factory BOSE system? If so that is how you should search. I have not run into the exact problem you have (still have factory head unit) but at least I can help point you in the right search direction.

That "10 pin" harness is your aux features like the Xm radio ,onstar, DVD player , ETc. etc.. you should pull out your harness and re-verify that you are tapped into the speakers from your HU to the truck. Sometimes I have noticed if you use a harness thats non onstar with an onstar system the wiring is different.
even though you dont use onstar you still have the hardware hooked up. so thats why i said to verify from the HU that you are running into the correct audio wires to the truck through the harness. chances are you may be just tapped into the wrong wire simple fix ...

On the 10 pin harness, you will need to power the pink wire. Run the remote turn on from your new stereo to this wire.

Hi all... this is my first post here and I am sure it will not be my last. I just installed an aftermarket into my '02 and like this thread, had no sound. I used the pink wire jump like JK suggested and it now works like a champ. My question is, is it possible to get the onstar and the rear passenger controls to still work? The secondary controls are not that important, just seems strange to have something there that does not work.

Thanks alot guys, and thanks for a great forum.

Former car audio installer here. Whenever we had a factory system we would do one of two things. Either run new wire to all the speakers (this was usually for smaller cars) or we would search for the factory amp disconnect it and start narrowing down what wires lead to speakers on the output with the 9v test.

In case you don't know the 9v test, you take a 9v battery and touch 2 leads to the terminals. This will cause the speaker to make an audible pop. Once you hear the pop you will want to look at the speaker that made the noise to see what direction it pops. If it pops out you have the correct polarity on the wires. If it pops out you will need to reverse the wires to have the positive and negative wires ran correctly.

Once you have figured out which speakers go to what wires you can run new wires from the aftermarket harness to the correct wires.

From the harness:
White is front driver side
Gray is front passenger
Green is rear driver side
Purple is rear passenger

Hope this helps. Good Luck!
