Back door speaker wire colors

[Christopher048]

I have a 2021 gmc sierra elevation and I am wanting to know do anyone know the back door speaker wire colors non bose. I am trying to tap in some tweeters. I can take the door panel off and pull the speaker but I don't want to go through all that but if anyone know it would help a lot verses taking off the panels and pulling the speaker. Thanks in advance

Hey, so if you're trying to add tweeters to your 2021 GMC Sierra Elevation (non-Bose), here's what I found: for the rear doors, the speaker wire colors are usually green for positive (+) and green/black for negative (-) on the left rear, and purple for positive (+) and purple/black for negative (-) on the right rear. That should save you from pulling off the whole door panel!
