I had an 03 tahoe same vehicle. Put in alpine radio. Here is what i did. I just got standard aftermarket wiring harness for vehicle which is the same regardless of bose or no bose. I hooked it up just like you would any radio, very straight forward. Here is what happened. I lost onstar (actually onstar was still there just could not hear them), l lost all audible alerts (door chime, headlight chime, memory seat chimes, etc,etc). These i didnt care about. What also happened was you are sending a amplified signal to the bose amp (under center console), what this does is make every volume adjustment very touchy (would get way loud way quick). However you can bypass the bose amp in the dash, look for the jumper to bose should be pretty easy to find, just unplug it and use it for the radio connecter (same connector, GM made just a loop to the center console amp then back up to speakers this way they could easily pre-wire reguardless of system. Then you will be powering all the speakers with deck power. u will lose sub tho, i was torn on which sounded better, i think running thru bose did just had to deal with volume touchyness.
