Trying to get the stereo into the old Mercedes from previous thread and I’m stuck. I bought some cheap Alpine speakers online and they came w no instructions or markings for + or -

They have small tweeters w their own little harnesses, it’s obvious enough that they plug into bigger speakers and then to the speaker wire. The problem is not knowing positive and negative. Believe it or not, I’ve had no luck searching for instructions or a manual online, including Alpine’s site.

Here are some photos, does anyone know the color scheme they use? The two wires are solid blue and black/blue. TIA as always.
