1997 Jetta dash tweeter wire color polarity

I'm swapping out the dash tweeters for 3.5in 2ways but don't have an adapter with it. What color (solid vs stripped) is for negative and which is positive? I believe the solid is ground and stripped is positive but here is a picture of the plug wires.

Thanks.

Anything with brown, will be ground.
