With that year vehicle it is recommended that you use a special harness because it has an factory amp and in order to get the proper wiring it requires the harness also if you don't use the harness you will loose your onstar and vehicle chimes and warning sounds.

SOURCE: need sterio wiring diagram for 1997 1500 gmc p/u ,factory harness

DON'T REMOVE FACTRORY CONNECTORS!!!!!!!!!!!!!! Spend $15 and buy a wiring kit. It plugs right into your vechile wires and the kit tells you what wires are what. Splicing the wires will lead to headaces down the road!!!

2004 envoy base I spliced the radio harness. Trying to hook up a aftermarket radio what's the color code and why is there two orange wires if the power is orange witch one is


This is why walmart and others sell a wiring kit that plugs one end into the stock wires and the other to your radio, One hot ware goes to always hot wire for clock and station presets, other goes to switched ignition so radio goes off with the key.

Do u have to bypass the factory amp to use a aftermarket head unit in a 2004 gmc envoy stanard system


If you do not have access to an aftermarket interface cable (some are available depending on brand and model of aftermarket radio), then yes, you have to bypass the amp if the new head unit has an internal amp, AND you wish to use the factory speakers with the new stereo.

There are many ways to do this, but if you want to do it yourself, the absolute best way is to get a copy of the dash harness wiring diagram from GM. This diagram will identify which pins in the radio dash harness connector run to the speakers and/or the amp, and whether you have to run new wires to the output side of the amp to connect to the speakers--this will not be specifically identified in the GM diagram (it will not say anything like 'to connect aftermarket radio, etc.), but it will be evident that you have to do this if there are no speaker pins in the in-dash connector.

2004 GMC Envoy Radio high pitched noise when off and static


In my opinion, it's almost certainly the radio. Even when turned off, it is still alive managing a few other things (like chimes) until you exit the vehicle, and I suspect that part of the radio is faulty.
