Nick, thanks for the 2002 GMC Envoy amp turn-on wire information contribution!
The 2002 GMC Envoy amp trigger/ power wire is blue with a yellow stripe.
Carl, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester and making sure all of your fuses are not blown. If all of your fuses are good, your 2002 GMC Envoy 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 your factory amplifier to output sound from your speakers. Hope this points you in the right direction. Good luck with your 2002 GMC Envoy stereo installation.
Hi, I have a 2002 gmc envoy and I just want to know if it has a built in amp in it. i installed an aftermarket stereo but cant get no sound through speakers.
Hi, I have a 2002 envoy and I just want to know if it has a built in amp in it. Thanks
I have a 2004 GMC Envoy. About 4 months ago, I had the radio replaced. Periodically, I noticed the door chime is very faint sounding and when this happens, the driver’s side speaker is not working. Have you heard of this before? How can I correct it? Thanks.
I plan on installing an after market stereo in a 2002 Envoy. Reading other forums, I have seen people talking about loosing the door chime if you do not have the correct wiring harness. Is this true? Thank you, Carl Bourke.
Hesham, if your vehicle is a United States Domestic Market (USDM) vehicle then your radio will only show odd numbers. Hope this helps. Good luck.
HI, I HAVE GMC ENVOY. I CAN’T CHANGE STATION ONE BY ONE LIKE 109.8 TO 109.9. SO WHAT I DO ?
